The procedure to remedy micromastia is breast enlargement, most commonly augmentation mammoplasty using breast implants. Other techniques available involve using muscle flap-based reconstructive surgery techniques (latissimus dorsi and rectus abdominus muscles), microsurgical reconstruction, or fat grafting.

Another potential treatment is hormonal breast enhancement, such as with estrogens.

The appearance of tuberous breasts can potentially be changed through surgical procedures, including the tissue expansion method and breast implants.

The procedure to change the appearance of tuberous breasts can be more complicated than a regular breast augmentation, and some plastic surgeons have specialist training in tuberous breast correction. As tuberous breasts are a congenital deformity, referral for treatment under the National Health Service may be possible in the United Kingdom. A starting point for those seeking such a referral may be a visit to their local General Practitioner. For those seeking non-surgical solutions, counseling may be recommended as a way of coming to terms with body image.

Most women with fibrocystic changes and no symptoms do not need treatment, but closer follow-up may be advised.

There is no widely accepted treatment or prevention strategy for fibrocystic condition. When treatment of symptoms is necessary it follows the same strategies as treatment for cyclical breast pain.

It is controversial whether benign breast conditions improve or worsen with oral contraceptives or hormone replacement therapy.

A few small-scale studies have indicated that the fibrocystic condition may be improved by dietary changes (especially by a reduced intake of caffeine and related methylxanthines or by a reduced intake of salt) and by vitamin supplements.

Small, preliminary studies have shown beneficial effects of iodine supplementation (such as reducing the presence of breast cysts, fibrous tissue plaques and breast pain) in women with fibrocystic breast changes, with elemental iodine (I) being more effective than iodide (I). It is noted that iodine supplementation, via an iodine-based modulation of estrogen influence in the breast, also appears to inhibit early cancer progression in small studies done on breast cancer cells in a lab.. Since treatment success in a lab is often not replicated in humans, more human research is necessary to determine if iodine supplementation prevents breast cancer

A U.S. National Institutes of Health fact sheet of 2011 reported on a randomized, double-blind, placebo-controlled clinical trial performed on 111 women affected by fibrosis and having a history of breast pain. In this trial, daily doses of iodine led to decreased in breast pain, tenderness and nodularity. It was emphasized that further research to clarify iodine's role in fibrocystic breast disease is needed and that large doses of iodine should only be used under the guidance of a physician.

Medical treatment has not proven consistently effective. Medical regimens have included tamoxifen, progesterone, bromocriptine, the gonadotropin-releasing hormone agonist leuprolide, and testosterone. Gestational macromastia has been treated with breast reduction drugs alone without surgery. Surgical therapy includes reduction mammaplasty and mastectomy. However, breast reduction is not clinically indicated unless at least 1.8 kg (4 lb) of tissue per breast needs to be removed. In the majority of cases of macromastia, surgery is medically unnecessary, depending on body height. Topical treatment includes regimens of ice to cool the breasts.

Treatment of hyperprolactinemia-associated macromastia with D receptor agonists such as bromocriptine and cabergoline has been found to be effective in some, but not all cases. Danazol, an antiestrogen and weak androgen, has also been found to be effective in the treatment of macromastia.

When hypertrophy occurs in adolescence, noninvasive treatments, including pharmaceutical treatment, hormone therapy, and steroid use are not usually recommended due to known and unknown side effects. Once a girl's breast growth rate has stabilized, breast reduction may be an appropriate choice. In some instances after aggressive or surgical treatment, the breast may continue to grow or re-grow, a complete mastectomy may be recommended as a last resort.

Pregnancy is recognized as the second most common reason for hypertrophy. When secondary to pregnancy, it may resolve itself without treatment after the pregnancy ends.

Breast cysts do not require treatment unless a cyst is large and painful or otherwise uncomfortable. In that case, draining the fluid from a breast cyst can ease symptoms.

Typical treatment involves a Needle aspiration biopsy. Aspirated cysts often recur (come back); definitive treatment may require surgery.

Draining the fluid and then waiting for the cyst to resolve is the main treatment applied in these cases. Moreover, if cysts are aspirated and the fluid looks normal, they do not require any other medical attention apart from following-up to make sure they have completely disappeared. Hormone therapy, by the means of oral contraceptives, is sometimes prescribed to reduce their recurrence and to regulate the menstrual cycle of the patient (which is likely to cause them in the first place). Danazol may also be prescribed to treat this condition and it is usually considered in patients on whom the non-medical treatment fails and the symptoms are intense.

Surgical removal of a breast cyst is necessary only in a few unusual circumstances. If an uncomfortable breast cyst recurs month after month, or if a breast cyst contains blood-tinged fluid and displays other worrisome signs, surgery may be considered.

One possible treatment is with anastrozole. Histrelin acetate (Supprelin LA), triptorelin or leuprolide, any GnRH agonists, may be used. Non-continuous usage of GnRH agonists stimulates the pituitary gland to release follicle stimulating hormone (FSH) and luteinizing hormone (LH). However, when used regularly, GnRH agonists cause a decreased release of FSH and LH. Prolonged use has a risk of causing osteoporosis. After stopping GnRH agonists, pubertal changes resume within 3 to 12 months.

Direct treatment is geared toward resolving hyperprolactinemic symptoms or reducing tumor size. Patients on medications that cause hyperprolactinaemia should have them withdrawn if possible. Patients with hypothyroidism should be given thyroid hormone replacement therapy. When symptoms are present, medical therapy is the treatment of choice. Patients with hyperprolactinemia and no symptoms (idiopathic or microprolactinoma) can be monitored without treatment. Consider treatment for women with amenorrhea. In addition, dual energy X-ray absorptiometry scanning should be considered to evaluate bone density. The persistent hypogonadism associated with hyperprolactinemia can lead to osteoporosis. Treatment significantly improves the patient's quality of life. If the goal is to treat hypogonadism only, patients with idiopathic hyperprolactinemia or microadenoma can be treated with estrogen replacement therapy and prolactin levels can be monitored. Radiation treatment is another option. However, the risk of hypopituitarism makes this a poor choice. It may be necessary for rapidly growing tumors, but its benefits in routine treatment have not been shown to outweigh the risks.

Danazol, an estrogen biosynthesis inhibitor, tamoxifen, an antagonistic modulator of the estrogen receptor, and bromocriptine, a prolactin-lowering D receptor agonist, are the main drugs used in the treatment of mastodynia and are effective.

Other medications and supplements have been found to be of benefit. Spironolactone (Aldactone), low dose oral contraceptives, low-dose estrogen have helped to relieve pain. Topical anti-inflammatory medications can be used for localized pain. For anti hormonal treatment, danazol (Danocrine) can be helpful. Tamoxifen citrate is used in some cases of severe breast pain. Vitamin E is not effective in relieving pain nor is Evening primrose oil. Vitamin B and Vitamin A have not been consistently found to be beneficial. Flaxseed has shown some activity in the treatment of cyclic mastalgia.

Pain may be relieved by the use of nonsteroidal anti-inflammatory drugs or, for more severe localized pain, by local anaesthetic. Pain may be relieved psychologically by reassurance that it does not signal a serious underlying problem, and an active life style can also effect an improvement.

Information regarding how the pain is real but not necessarily caused by disease can help to understand the problem. Learning breast self-examination helps to orient the woman to normal and expected texture and structure of the breast and nipple. Yearly breast exams may be suggested. Counseling can also be to describe changes that vary during the monthly cycle. Women on hormone replacement therapy may benefit from a dose adjustment. Another non-pharmacological measure to help relieve symptoms of pain may be to use good bra support. Breasts change during adolescence and menopause and refitting may be beneficial. Applying heat and/or ice can bring relief. Dietary changes may also help with the pain. Methylxanthines can be eliminated from the diet to see if a sensitivity is present. Some clinicians recommending a reduction in salt, though no evidence supports this practice.

There are usually no adverse side effects to this condition. In almost all cases it subsides after menopause. A possible complication arises through the fact that cancerous tumors may be more difficult to detect in women with fibrocystic changes.

Most fibroadenomas are simply monitored. Some are treated by surgical excision. They are removed with a small margin of normal breast tissue if the preoperative clinical investigations are suggestive of the necessity of this procedure. A small amount of normal tissue must be removed in case the lesion turns out to be a phyllodes tumour on microscopic examination.

Because needle biopsy is often a reliable diagnostic investigation, some doctors may decide not to operate to remove the lesion, and instead opt for clinical follow-up to observe the lesion over time using clinical examination and mammography to determine the rate of growth, if any, of the lesion. A growth rate of less than sixteen percent per month in women under fifty years of age, and a growth rate of less than thirteen percent per month in women over fifty years of age have been published as safe growth rates for continued non-operative treatment and clinical observation.

Some fibroadenomas respond to treatment with ormeloxifene.

Fibroadenomas have not been shown to recur following complete excision or transform into phyllodes tumours following partial or incomplete excision.

Male primary or hypergonadogropic hypogonadism is often treated with testosterone replacement therapy if they are not trying to conceive. Adverse effects of testosterone replacement therapy include increased cardiovascular events (including strokes and heart attacks) and death. The Food and Drug Administration (FDA) stated in 2015 that neither the benefits nor the safety of testosterone have been established for low testosterone levels due to aging. The FDA has required that testosterone pharmaceutical labels include warning information about the possibility of an increased risk of heart attacks and stroke.

Commonly used testosterone replacement therapies include transdermal (through the skin) using a patch or gel, injections, or pellets. Oral testosterone is no longer used in the U.S. because it is broken down in the liver and rendered inactive; it also can cause severe liver damage. Like many hormonal therapies, changes take place over time. It may take as long as 2–3 months at optimum level to reduce the symptoms, particularly wordfinding and cognitive dysfunction. Testosterone levels in the blood should be evaluated to ensure the increase is adequate. Levels between 400 and 700 ng/dL are considered appropriate mid-dose levels. Treatment usually starts with 200 mg intramuscular testosterone, repeated every 14 days.

While historically, men with prostate cancer risk were warned against testosterone therapy, that has shown to be a myth.

Other side effects can include an elevation of the hematocrit to levels that require blood withdrawal (phlebotomy) to prevent complications from excessively thick blood. Gynecomastia (growth of breasts in men) sometimes occurs. Finally, some physicians worry that obstructive sleep apnea may worsen with testosterone therapy, and should be monitored.

Another treatment for hypogonadism is human chorionic gonadotropin (hCG). This stimulates the LH receptor, thereby promoting testosterone synthesis. This will not be effective in men who simply cannot make testosterone anymore (primary hypogonadism) and the failure of hCG therapy is further support for the existence of true testicular failure in a patient. It is particularly indicated in men with hypogonadism who wish to retain their fertility, as it does not suppress spermatogenesis like testosterone replacement therapy does.

For both men and women, an alternative to testosterone replacement is low-dose clomifene treatment, which can stimulate the body to naturally increase hormone levels while avoiding infertility and other side effects that can result from direct hormone replacement therapy. This therapy has only been shown helpful for men with secondary hypogonadism. Recent studies have shown it can be safe and effective monotherapy for up to 2 years in patients with intact testicular function and impaired function of the HPTA(http://www.nature.com/ijir/journal/v15/n3/full/3900981a.html). Clomifene blocks estrogen from binding to some estrogen receptors in the hypothalamus, thereby causing an increased release gNRH and subsequently LH from the pituitary. Clomifene is a Selective Estrogen Reuptake Modulator (SERM).

Generally clomifene does not have adverse effects at the doses used for this purpose. Clomifene at much higher doses is used to induce ovulation and has significant adverse effects in such a setting.

For women with hypogonadism, estradiol and progesterone are often replaced. Some types of fertility defects can be treated, others cannot. Some physicians also give testosterone to women, mainly to increase libido.

General indications for pituitary surgery include patient drug intolerance, tumors resistant to medical therapy, patients who have persistent visual field defects in spite of medical treatment, and patients with large cystic or hemorrhagic tumors.

The development of breast cysts may be prevented to some degree, according to the majority of the specialists. The recommended measures one is able to take in order to avoid the formation of the cysts include practicing good health and avoiding certain medications, eating a balanced diet, taking necessary vitamins and supplements, getting exercise, and avoiding stress.

Although caffeine consumption does not have a scientifically proved connection with the process of cyst development, many women claim that their symptoms are relieved if avoiding it. Some doctors recommend reducing the amount of caffeine in one's diet in terms of both beverages and foods (such as chocolate). Also reducing salt intake may help in alleviating the symptoms of breast cysts, although, again, there is no scientific linkage between these two. Excessive sugar consumption as well as undetected food allergies, such as to gluten or lactose, may also contribute to cyst development.

Any deformity of the breasts is only apparent during puberty and this may lead to psychosexual problems with girls in very early puberty being affected psychologically due to the unusual shape of the breast. Surgical papers about the techniques useful in correcting tubular breasts note that

even when results are not perfect, the psychological impact of treatment is immense, with notable improvements in self-esteem to the level where the person engages in normal social activities.

Initially, an evaluation of malignancy is always indicated. If no abnormality is found, then a surgical duct excision may resolve the symptoms. Treatment also depends on whether single-duct or multiple-duct discharge is present, and whether the symptoms of nipple discharge are distressing to the patient. In some cases, there may be no need for any further intervention; in others, microdochectomy or a total duct excision may be appropriate. If the patient wishes to conserve the ability to breastfeed and only single-duct discharge is present, then ductoscopy or galactography should be considered in view of performing a localised duct excision. Once the cause of the nipple discharge is found, it will be treated by the health provider who will evaluate:

- Whether changing any medicine that has caused the discharge is appropriate

- Whether any lumps should be removed

- Whether some or all of the breast ducts should be removed

- If a prescription for cream to treat skin changes around the nipple will be helpful

- If medicines to treat a health condition are required

If all the tests are normal, treatment may not be necessary. A follow up mamogram mammogram and physical exam may be prescribed within 1 year.

Some women with ptosis choose to undergo plastic surgery to make their breasts less ptotic. Plastic surgeons offer several procedures for lifting sagging breasts. Surgery to correct the size, contour, and elevation of sagging breasts is called mastopexy. Women can also choose breast implants, or may undergo both procedures. The breast-lift procedure surgically elevates the parenchymal tissue (breast mass), cuts and re-sizes the skin envelope, and transposes the nipple-areola complex higher upon the breast hemisphere. If sagging is present and the woman opts not to undergo mastopexy, implants are typically placed above the muscle, to fill out the breast skin and tissue. Submuscular placement can result in deformity. In these cases, the implant appears to be high on the chest, while the natural breast tissue hangs down over the implant.

Treatment may consist of surgery in the case of tumors, lower doses of estrogen in the case of exogenously-mediated estrogen excess, and estrogen-suppressing medications like gonadotropin-releasing hormone analogues and progestogens. In addition, androgens may be supplemented in the case of males.

Several treatments have been found to be effective in managing AES, including aromatase inhibitors and gonadotropin-releasing hormone analogues in both sexes, androgen replacement therapy with non-aromatizable androgens such as DHT in males, and progestogens (which, by virtue of their antigonadotropic properties at high doses, suppress estrogen levels) in females. In addition, male patients often seek bilateral mastectomy, whereas females may opt for breast reduction if warranted.

Medical treatment of AES is not absolutely necessary, but it is recommended as the condition, if left untreated, may lead to excessively large breasts (which may necessitate surgical reduction), problems with fertility, and an increased risk of endometriosis and estrogen-dependent cancers such as breast and endometrial cancers later in life. At least one case of male breast cancer has been reported.

Administration of GH has no effect on IGF-1 production, therefore treatment is mainly by biosynthetic IGF-1. IGF-1 must be taken before puberty to be effective.

The drug product Increlex (mecasermin), developed by the company Tercica, now Genentech, was approved by the US Food and Drug Administration in August 2005 for replacing IGF-1 in patients who are deficient.

IPLEX (Mecasermin rinfabate) is composed of recombinant human IGF-1 (rhIGF-1) and its binding protein IGFBP-3. It was approved by the U.S. Food and Drug Administration (FDA) in 2005 for treatment of primary IGF-1 deficiency or GH gene deletion. Side effects from IPLEX are hypoglycemia. IPLEX's manufacturing company, Insmed, after selling its protein production facility, can no longer develop proteins, thus can no longer manufacture IPLEX as of a statement released in July 2009.

Hormone replacement therapy (HRT) with estrogen can be used to treat hypoestrogenism both in premenopausal and postmenopausal women.

Micromastia (also called hypomastia, breast aplasia, breast hypoplasia, or mammary hypoplasia) is a medical term describing the postpubertal underdevelopment of a woman's breast tissue. Just as it is impossible to define 'normal' breast size, there is no objective definition of micromastia. Breast development is commonly asymmetric and one or both breasts may be small. This condition may be a congenital defect associated with underlying abnormalities of the pectoral muscle (as in Poland's syndrome), related to trauma (typically surgery or radiotherapy) or it may be a more subjective aesthetic description.

Self perceived micromastia involves a discrepancy between a person's body image, and her internalized images of appropriate or desirable breast size and shape. Societal ideals over breast size vary over time, but there exist many conceived ideas involving breasts and sexual attractiveness and identity across different cultures.

Upon diagnosis, estrogen and progesterone therapy is typically commenced, promoting the development of female characteristics.

The consequences of streak gonads to a person with Swyer syndrome:

1. Gonads cannot make estrogen, so the breasts will not develop and the uterus will not grow and menstruate until estrogen is administered. This is often given transdermally.

2. Gonads cannot make progesterone, so menstrual periods will not be predictable until progestin is administered, usually as a pill.

3. Gonads cannot produce eggs so conceiving children naturally is not possible. A woman with a uterus and ovaries but without female gamete is able to become pregnant by implantation of another woman's fertilized egg (embryo transfer).

4. Streak gonads with Y chromosome-containing cells have a high likelihood of developing cancer, especially gonadoblastoma. Streak gonads are usually removed within a year or so of diagnosis since the cancer can begin during infancy.

Hypertension and mineralocorticoid excess is treated with glucocorticoid replacement, as in other forms of CAH.

Most genetic females with both forms of the deficiency will need replacement estrogen to induce puberty. Most will also need periodic progestin to regularize menses. Fertility is usually reduced because egg maturation and ovulation is poorly supported by the reduced intra-ovarian steroid production.

The most difficult management decisions are posed by the more ambiguous genetic (XY) males. Most who are severely undervirilized, looking more female than male, are raised as females with surgical removal of the nonfunctional testes. If raised as males, a brief course of testosterone can be given in infancy to induce growth of the penis. Surgery may be able to repair the hypospadias. The testes should be salvaged by orchiopexy if possible. Testosterone must be replaced in order for puberty to occur and continued throughout adult life.

There is no ‘standard treatment’ for people with CFND due to the large variations in phenotypic expression. Each patient needs to be assessed and treated based on their specific presentation in order to restore the aesthetic and functional balance.

Surgical corrections for the main symptoms;

- Craniosynostosis correction: The preferred age for this procedure is between 6–9 months of age. Performing this surgery at such an early age can limit the further development of facial asymmetry, if the asymmetry is caused by the craniosynostosis, and prevents prolonged elevated intracranial pressure (ICP). However, the data for the exact risk of an elevated intracranial pressure for patients with CFND is lacking in the published literature. The surgery involves a frontal bone advancement in combination with remodellation of the supraorbital rim.

- Orbital hypertelorism: It is preferred to wait with this treatment until the age of 5–8 years old, after permanent dentition. The procedures that can be performed are the facial bipartition and the box osteotomy. Facial bipartition is the more preferable choice as there are less additional corrections needed, as well as providing a more stable long-term result after treatment. After the correction of the orbitas, the medial corners of the eyes are put more into a horizontal line.

- Nasal deformity correction: The correction of the broad nasal base is simultaneously done with the orbital hypertelorism repair. This is for good alignment of the eyes with the nose for the best aesthetic result. A bifid nose tip will only be treated at the age of 18, when the patient's skeleton has fully matured.

The FDA has approved cryoablation of a fibroadenoma as a safe, effective and minimally-invasive alternative to open surgical removal in 2001. In the procedure, ultrasound imaging is used to guide a probe into the mass of breast tissue. Extremely cold temperatures are then used to destroy the abnormal cells, and over time the cells are reabsorbed into the body. The procedure can be performed as an outpatient surgery using local anesthesia only, and leaves substantially less scarring than open surgical procedures and no breast tissue deformation.

The American Society of Breast Surgeons recommends the following criteria to establish a patient as a candidate for cryoablation of a fibroadenoma:

1. The lesion must be sonographically visible.

2. The diagnosis of a fibroadenoma must be confirmed histologically.

3. The lesion should be less than 4 cm in diameter.
