Treatment of endometrial hyperplasia is individualized, and may include hormonal therapy, such as cyclic or continuous progestin therapy, or hysterectomy.

Polyps can be surgically removed using curettage with or without hysteroscopy. When curettage is performed without hysteroscopy, polyps may be missed. To reduce this risk, the uterus can be first explored using grasping forceps at the beginning of the curettage procedure. Hysteroscopy involves visualising the endometrium (inner lining of the uterus) and polyp with a camera inserted through the cervix. If it is a large polyp, it can be cut into sections before each section is removed. If cancerous cells are discovered, a hysterectomy (surgical removal of the uterus) may be performed. A hysterectomy would usually not be considered if cancer has been ruled out. Whichever method is used, polyps are usually treated under general anesthetic.

It is unclear if removing polyps affects fertility as it has not been studied.

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.

Laparoscopic surgical approaches include of ovarian adhesions and of endometriomas. Endometriomas frequently require surgical removal and excision is considered to be superior in terms of permanent removal of the disease and pain relief. Surgery can sometimes have the effect of improving fertility but can have the adverse effect of leading to increases in cycle day 2 or 3 FSH for many patients.

Laser surgery and cauterization are considered to be far less effective and only burn the top layer of endometrial tissue, allowing for the endometrioma and endometriosis to grow back quickly. Likewise, endometrioma drainage or sclerotherapy are somewhat controversial technique for removing endometriomas with varied degrees of success. Conservative surgery can be performed to preserve fertility in younger patients but as earlier stated can have the effect of raising FSH values and making the ovaries less productive, especially if functional ovarian tissue is removed in the surgical process.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used first in patients with pelvic pain, particularly if the diagnosis of endometriosis has not been definitively (excision and biopsy) established. The goal of directed medical treatment is to achieve an anovulatory state. Typically, this is achieved initially using hormonal contraception. This can also be accomplished with progestational agents (i.e., medroxyprogesterone acetate), danazol, gestrinone, or gonadotropin-releasing hormone agonists (GnRH), as well as other less well-known agents. These agents are generally used if oral contraceptives and NSAIDs are ineffective. GnRH can be combined with estrogen and progestogen (add-back therapy) without loss of efficacy but with fewer hypoestrogenic symptoms. These medications are often ineffective in treating endometriomas and any relief is short lived while taking the medications. Hormonal treatment has a large number of sometimes permanent side effects, such as hot flushes, loss of bone mass, deepening of voice, weight gain, and facial hair growth.

The primary treatment is surgical. FIGO-cancer staging is done at the time of surgery which consists of peritoneal cytology, total hysterectomy, bilateral salpingo-oophorectomy, pelvic/para-aortic lymphadenectomy, and omentectomy. The tumor is aggressive and spreads quickly into the myometrium and the lymphatic system. Thus even in presumed early stages, lymphadenectomy and omentectomy should be included in the surgical approach. If the tumor has spread surgery is cytoreductive followed by radiation therapy and/or chemotherapy.

In a study to determine if adjuvant therapy should be used in patients with stage I UPSC who had undergone surgery, no increased survival was seen when radiation therapy was added versus observation, while the postsurgical treatment with chemotherapy may be beneficial but more data are needed.

A study of the usefulness of platinum-based chemotherapy as an adjuvant after surgery of stage I patients showed that patients with stage 1A who had no residual disease in the hysterectomy specimen had no recurrence regardless if chemotherapy was used or not, however, patients with stage 1A disease with residual disease in the hysterectomy specimen had no recurrence with platinum-based therapy, but those who had no such chemotherapy showed recurrence in 43%. Similarly, patients with stage 1B disease with chemotherapy had no recurrence, while those without chemotherapy had a high degree (77%) of recurrence.

The treatment of hyperplasia would consist upon "which"; in the case of benign prostate hyperplasia the combination of alpha-1-receptor blockers and 5-alpha-reductase inhibitors are effective.

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.

The management of PASH is controversial. Excision may be indicated in enlarging masses or lesions with atypical features.

LCIS may be treated with close clinical follow-up and mammographic screening, tamoxifen or related hormone controlling drugs to reduce the risk of developing cancer, or bilateral prophylactic mastectomy. Some surgeons consider bilateral prophylactic mastectomy to be overly aggressive treatment except for certain high-risk cases.

There are a number of possible additional therapies. Surgery can be followed by radiation therapy and/or chemotherapy in cases of high-risk or high-grade cancers. This is called adjuvant therapy.

Adjuvant chemotherapy is a recent innovation, consisting of some combination of paclitaxel (or other taxanes like docetaxel), doxorubicin (and other anthracyclines), and platins (particularly cisplatin and carboplatin). Adjuvant chemotherapy has been found to increase survival in stage III and IV cancer more than added radiotherapy. Mutations in mismatch repair genes, like those found in Lynch syndrome, can lead to resistance against platins, meaning that chemotherapy with platins is ineffective in people with these mutations. Side effects of chemotherapy are common. These include hair loss, low neutrophil levels in the blood, and gastrointestinal problems.

In cases where surgery is not indicated, palliative chemotherapy is an option; higher-dose chemotherapy is associated with longer survival. Palliative chemotherapy, particularly using capecitabine and gemcitabine, is also often used to treat recurrent endometrial cancer.

In a recent study, about 60% of USCs were found to overexpress the protein HER2/neu—the same one that is overexpressed in some breast cancers. The monoclonal antibody trastuzumab (Herceptin) is currently being tested as a therapy for this subset of USCs.

The antibody trastuzumab (Herceptin), which is used to treat breast cancers that overexpress the HER2/neu protein, has been tried with some success in a phase II trial in women with UPSCs that overexpress HER2/neu.

ADH, if found on a surgical (excisional) biopsy of a mammographic abnormality, does not require any further treatment, only mammographic follow-up.

If ADH is found on a core (needle) biopsy (a procedure which generally does not excise a suspicious mammographic abnormality), a surgical biopsy, i.e. a breast lumpectomy, to completely excise the abnormality and exclude breast cancer is the typical recommendation.

Endometrial polyps are usually benign although some may be precancerous or cancerous. About 0.5% of endometrial polyps contain adenocarcinoma cells. Polyps can increase the risk of miscarriage in women undergoing IVF treatment. If they develop near the fallopian tubes, they may lead to difficulty in becoming pregnant. Although treatments such as hysteroscopy usually cure the polyp concerned, recurrence of endometrial polyps is frequent. Untreated, small polyps may regress on their own.

Treatment depends on the cause. In cases where malignancy is ruled out, hormone supplementation or the therapeutic use of hormonal contraception is usually recommended to induce bleeding on a regular schedule. Selective progesterone receptor modulators (SPRMs) are sometimes used to stop uterine bleeding.

Therapy is based on staging and patient condition and utilizes one or more of the following approaches.

Surgery is the mainstay of therapy if feasible involving total abdominal hysterectomy with bilateral salpingo-oophorectomy. Other approaches include radiation therapy, chemotherapy, and hormonal therapy.

Prognosis is relatively poor.

Broadly speaking, surgical management of adenomyosis is split into two categories: uterine-sparing and non-uterine-sparing procedures. Uterine-sparing procedures are surgical operations that do not include surgical removal of the uterus. Some uterine-sparing procedures have the benefit of improving fertility or retaining the ability to carry a pregnancy to term. In contrast, some uterine-sparing procedures worsen fertility or even result in complete sterility. The impact of each procedure on a woman's fertility is of particular concern and typically guides the selection. Non-uterine-sparing procedures, by definition, include surgical removal of the uterus and consequently they will all result in complete sterility.

Adenomyosis can only be cured definitively with surgical removal of the uterus. As adenomyosis is responsive to reproductive hormones, it reasonably abates following menopause when these hormones decrease. In women in their reproductive years, adenomyosis can typically be managed with the goals to provide pain relief, to restrict progression of the process, and to reduce significant menstrual bleeding.

The average age at time of EIN diagnosis is approximately 52 years, compared to approximately 61 years for carcinoma. The timeframe and likelihood of EIN progression to cancer, however, is not constant amongst all women. Some cases of EIN are first detected as residual premalignant disease in women who already have carcinoma, whereas other EIN lesions disappear entirely and never lead to cancer. For this reason, treatment benefits and risks must be individualized for each patient under the guidance of an experienced physician.

Risk factors for development of EIN and the endometrioid type of endometrial carcinoma include exposure to estrogens without opposing progestins, obesity, diabetes, and rare hereditary conditions such as hereditary nonpolyposis colorectal cancer. Protective factors include use of combined oral contraceptive pills (low dose estrogen and progestin), and prior use of a contraceptive intrauterine device.

HGPIN in isolation does not require treatment. In prostate biopsies it is not predictive of prostate cancer in one year if the prostate was well-sampled, i.e. if there were 8 or more cores.

The exact timing of repeat biopsies remains an area of controversy, as the time required for, and probability of HGPIN transformations to prostate cancer are not well understood.

The rate at which breast cancer (ductal carcinoma in situ "or" invasive mammary carcinoma (all breast cancer except DCIS and LCIS)) is found at the time of a surgical (excisional) biopsy, following the diagnosis of ADH on a core (needle) biopsy varies considerably from hospital-to-hospital (range 4-54%). In two large studies, the conversion of an ADH on core biopsy to breast cancer on surgical excision, known as "up-grading", is approximately 30%.

Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus.

Most cases of endometrial hyperplasia result from high levels of estrogens, combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this tissue. This may occur in a number of settings, including obesity, polycystic ovary syndrome, estrogen producing tumours (e.g. granulosa cell tumour) and certain formulations of estrogen replacement therapy. Endometrial hyperplasia is a significant risk factor for the development or even co-existence of endometrial cancer, so careful monitoring and treatment of women with this disorder is essential.

Prognosis of the CC is affected by age, stage, and histology as well as treatment

The primary treatment is surgical. FIGO-cancer staging is done at the time of surgery which consists of peritoneal cytology, total hysterectomy, bilateral salpingo-oophorectomy, pelvic/para-aortic lymphadenectomy, and omentectomy. The tumor is aggressive and spreads quickly into the myometrium and the lymphatic system. Thus even in presumed early stages, lymphadenectomy and omentectomy should be included in the surgical approach. If the tumor has spread surgery is cytoreductive followed by radiation therapy and/or chemotherapy.

The five years survival was reported to be 68%.
