Most vaginal cancers do not cause signs or symptoms early on. When vaginal cancer does cause symptoms, they may include:
- Vaginal discharge or abnormal bleeding.
- Unusally heavy flow of blood
- Bleeding after menopause
- Bleeding between periods; or any other
- Bleeding that is longer than normal for you
- Blood in the stool or urine
- Frequent or urgent need to urinate
- Feeling constipated
- pain during sexual intercourse
- a lump or growth in the vagina that can be felt
Enlarged pelvic lymph nodes can sometimes be palpated.
Vaginal cancer is any type of cancer that forms in the tissues of the vagina. Primary vaginal cancer is rare in the general population of women and is usually a squamous-cell carcinoma. Metastases are more common. Vaginal cancer occurs more often in women over age 50, but can occur at any age, even in infancy. It often can be cured if found and treated in early stages. Surgery alone or surgery combined with pelvic radiation is typically used to treat vaginal cancer.
Many malignancies can develop in vulvar structures. The signs and symptoms can include:
- Itching, burn, or bleeding on the vulva that does not go away.
- Changes in the color of the skin of the vulva, so that it looks redder or whiter than is normal.
- Skin changes in the vulva, including what looks like a rash or warts.
- Sores, lumps, or ulcers on the vulva that do not go away.
- Pain in the pelvis, especially during urination or sex.
Typically, a lesion presents in the form of a lump or ulcer on the labia majora and may be associated with itching, irritation, local bleeding or discharge, in addition to pain with urination or pain during sexual intercourse. The labia minora, clitoris, perineum and mons are less commonly involved. Due to modesty or embarrassment, patients may put off seeing a doctor.
Melanomas tend to display the typical asymmetry, uneven borders and dark discoloration as do melanomas in other parts of the body.
Adenocarcinoma can arise from the Bartholin gland and present with a painful lump.
The terms uterine cancer and womb cancer may refer to any of several different types of cancer which occur in the uterus, namely:
- Endometrial cancer:
- Cervical cancer arises from the transformation zone of the cervix, the lower portion of the uterus and connects to the upper aspect of the vagina.
- Uterine sarcomas: sarcomas of the myometrium, or muscular layer of the uterus, are most commonly leiomyosarcomas.
- Gestational trophoblastic disease relates to neoplastic processes originating from tissue of a pregnancy that often is located in the uterus.
Uterine cancer, also known as womb cancer, is any type of cancer that emerges from the tissue of the uterus. It can refer to several types of cancer, with cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries. Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from developed countries.
Risk factors depend on specific type, but obesity, older age, and human papillomavirus infection add the greatest risk of developing uterine cancer. Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop. If caught early, most types of uterine cancer can be cured using surgical or medical methods. When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of chemotherapy, radiation therapy, or surgery may be required.
Vaginal bleeding or spotting in women after menopause occurs in 90% of endometrial cancer. Bleeding is especially common with adenocarcinoma, occurring in two-thirds of all cases. Abnormal menstrual cycles or extremely long, heavy, or frequent episodes of bleeding in women before menopause may also be a sign of endometrial cancer.
Symptoms other than bleeding are not common. Other symptoms include thin white or clear vaginal discharge in postmenopausal women. More advanced disease shows more obvious symptoms or signs that can be detected on a physical examination. The uterus may become enlarged or the cancer may spread, causing lower abdominal pain or pelvic cramping. Painful sexual intercourse or painful or difficult urination are less common signs of endometrial cancer. The uterus may also fill with pus (pyometrea). Of women with these less common symptoms (vaginal discharge, pelvic pain, and pus), 10–15% have cancer.
Basal cell carcinoma makes up about 1–2% of vulvar cancer. These tend to be slow-growing lesions on the labia majora but can occur anywhere on the vulva. Their behavior is similar to basal cell cancers in other locations. They often grow locally and have low risk for deep invasion or metastasis.
Treatment involves excision, but these lesions have a tendency to recur if not completely removed.
The early stages of cervical cancer may be completely free of symptoms. Vaginal bleeding, contact bleeding (one most common form being bleeding after sexual intercourse), or (rarely) a vaginal mass may indicate the presence of malignancy. Also, moderate pain during sexual intercourse and vaginal discharge are symptoms of cervical cancer. In advanced disease, metastases may be present in the abdomen, lungs, or elsewhere.
Symptoms of advanced cervical cancer may include: loss of appetite, weight loss, fatigue, pelvic pain, back pain, leg pain, swollen legs, heavy vaginal bleeding, bone fractures, and (rarely) leakage of urine or feces from the vagina. Bleeding after douching or after a pelvic exam is a common symptom of cervical cancer.
Neuroendocrine carcinoma affects many different parts of the body.
In the cervix, it is a rare, but very aggressive form of cervical cancer. In its early stages, neuroendocrine carcinoma is asymptomatic (not showing or producing indications of a disease or other medical condition). In more advanced stages, symptoms of Neuroendocrine carcinoma of the cervix are: abnormal vaginal bleeding, increased vaginal discharge, and pelvic pain, painful urination, pain during sex, tiredness, leg swelling, and backache. When left untreated, metastasis or even death may occur.
Endometrial cancer is a cancer that arises from the endometrium (the lining of the uterus or womb). It is the result of the abnormal growth of cells that have the ability to invade or spread to other parts of the body. The first sign is most often vaginal bleeding not associated with a menstrual period. Other symptoms include pain with urination, pain during sexual intercourse, or pelvic pain. Endometrial cancer occurs most commonly after menopause.
Approximately 40% of cases are related to obesity. Endometrial cancer is also associated with excessive estrogen exposure, high blood pressure and diabetes. Whereas taking estrogen alone increases the risk of endometrial cancer, taking both estrogen and a progestogen in combination, as in most birth control pills, decreases the risk. Between two and five percent of cases are related to genes inherited from the parents. Endometrial cancer is sometimes loosely referred to as "uterine cancer", although it is distinct from other forms of uterine cancer such as cervical cancer, uterine sarcoma, and trophoblastic disease. The most frequent type of endometrial cancer is endometrioid carcinoma, which accounts for more than 80% of cases. Endometrial cancer is commonly diagnosed by endometrial biopsy or by taking samples during a procedure known as dilation and curettage. A pap smear is not typically sufficient to show endometrial cancer. Regular screening in those at normal risk is not called for.
The leading treatment option for endometrial cancer is abdominal hysterectomy (the total removal by surgery of the uterus), together with removal of the fallopian tubes and ovaries on both sides, called a bilateral salpingo-oophorectomy. In more advanced cases, radiation therapy, chemotherapy or hormone therapy may also be recommended. If the disease is diagnosed at an early stage, the outcome is favorable, and the overall five-year survival rate in the United States is greater than 80%.
In 2012, endometrial cancers newly occurred in 320,000 women and caused 76,000 deaths. This makes it the third most common cause of death in cancers which only affect women, behind ovarian and cervical cancer. It is more common in the developed world and is the most common cancer of the female reproductive tract in developed countries. Rates of endometrial cancer have risen in a number of countries between the 1980s and 2010. This is believed to be due to the increasing number of elderly people and increasing rates of obesity.
Though Bartholin gland carcinoma is rare, along with other unusual Bartholin gland growths, it many not be the typical practice for clinicians to consider lesions malignant. Early diagnosis can help to prevent the cancer from the glands to surrounding. Though malignancies of the Bartholin gland are rare clinicians biopsy Bartholin gland lesions in older women or when the growth reoccurs or does not respond to original treatment.
Bartholin gland can be differentiated by histology to determine whether the malignancy is due to squamous cell carcinoma, adenoid cystic carcinoma, or adenocarcinomas.
It has been observed that HPV18 is the most prevalent type in Small cell cervical cancer.
Like other types of cervical cancer it seems to be associated with high-risk (e.g. 16, 18, 31) HPV Infection.
Bladder cancer characteristically causes blood (redness) in the urine. This blood in the urine may be visible to the naked eye (gross/macroscopic hematuria) or detectable only by microscope (microscopic hematuria). Hematuria is the most common symptom in bladder cancer. It occurs in approximately 80–90% of the patients.
Other possible symptoms include pain during urination, frequent urination, or feeling the need to urinate without being able to do so. These signs and symptoms are not specific to bladder cancer, and are also caused by non-cancerous conditions, including prostate infections, over-active bladder and cystitis. There are many other causes of hematuria, such as bladder or ureteric stones, infection, kidney disease, kidney cancers and vascular malformations.
Patients with advanced disease refer pelvic or bony pain, lower-extremity edema, or flank pain.
Rarely a palpable mass can be detected on physical examination.
Cervical ectropion can be associated with excessive but non-purulent vaginal discharge due to the increased surface area of columnar epithelium containing mucus-secreting glands. It may also give rise to post-coital bleeding, as fine blood vessels present within the columnar epithelium are easily traumatised.
"Cervical ectropion" (or cervical eversion) is a condition in which the cells from the ‘inside’ of the cervical canal known as glandular cells (or columnar epithelium), are present on the ‘outside’ of the vaginal portion of the cervix. The cells on the ‘outside’ of the cervix are called squamous epithelial cells. Where the two cells meet is called the transformation zone also known as the stratified squamous epithelium. Although having this condition is not an abnormality, it is indistinguishable from early cervical cancer. When at a routine check up, it can be seen by the nurse when a cervical screening test (or smear test) is done. The area may look red because the glandular cells are red. While many women are born with cervical ectropion, it can be caused by a number of reasons, such as:
- Hormonal changes, so meaning it can be common in young women.
- Taking “the pill” to protect from pregnancy
- Pregnancy
Cervical cancer is a cancer arising from the cervix. It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. Early on, typically no symptoms are seen. Later symptoms may include abnormal vaginal bleeding, pelvic pain, or pain during sexual intercourse. While bleeding after sex may not be serious, it may also indicate the presence of cervical cancer.
Human papillomavirus infection (HPV) causes more than 90% of cases; most people who have had HPV infections, however, do not develop cervical cancer. Other risk factors include smoking, a weak immune system, birth control pills, starting sex at a young age, and having many sexual partners, but these are less important. Cervical cancer typically develops from precancerous changes over 10 to 20 years. About 90% of cervical cancer cases are squamous cell carcinomas, 10% are adenocarcinoma, and a small number are other types. Diagnosis is typically by cervical screening followed by a biopsy. Medical imaging is then done to determine whether or not the cancer has spread.
HPV vaccines protect against between two and seven high-risk strains of this family of viruses and may prevent up to 90% of cervical cancers. As a risk of cancer still exists, guidelines recommend continuing regular Pap tests. Other methods of prevention include: having few or no sexual partners and the use of condoms. Cervical cancer screening using the Pap test or acetic acid can identify precancerous changes which when treated can prevent the development of cancer. Treatment of cervical cancer may consist of some combination of surgery, chemotherapy, and radiation therapy. Five-year survival rates in the United States are 68%. Outcomes, however, depend very much on how early the cancer is detected.
Worldwide, cervical cancer is both the fourth-most common cause of cancer and the fourth-most common cause of death from cancer in women. In 2012, an estimated 528,000 cases of cervical cancer occurred, with 266,000 deaths. This is about 8% of the total cases and total deaths from cancer. About 70% of cervical cancers occur in developing countries. In low-income countries, it is the most common cause of cancer death. In developed countries, the widespread use of cervical screening programs has dramatically reduced rates of cervical cancer. In medical research, the most famous immortalised cell line, known as HeLa, was developed from cervical cancer cells of a woman named Henrietta Lacks.
Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. It is a disease in which cells grow abnormally and have the potential to spread to other parts of the body. Symptoms include blood in the urine, pain with urination, and low back pain.
Risk factors for bladder cancer include smoking, family history, prior radiation therapy, frequent bladder infections, and exposure to certain chemicals. The most common type is transitional cell carcinoma. Other types include squamous cell carcinoma and adenocarcinoma. Diagnosis is typically by cystoscopy with tissue biopsies. Staging of the cancer is typically determined by medical imaging such as CT scan and bone scan.
Treatment depends on the stage of the cancer. It may include some combination of surgery, radiation therapy, chemotherapy, or immunotherapy. Surgical options may include transurethral resection, partial or complete removal of the bladder, or urinary diversion. Typical five-year survival rates in the United States are 77%.
Bladder cancer, as of 2015, affects about 3.4 million people with 430,000 new cases a year. Age of onset is most often between 65 and 85 years of age. Males are more often affected than females. In 2015 it resulted in 188,000 deaths.
Esophageal cancer may be due to either squamous cell carcinoma (ESCC) or adenocarcinoma (EAC). SCCs tend to occur closer to the mouth, while adenocarcinomas occur closer to the stomach. Dysphagia (difficulty swallowing, solids worse than liquids) and painful swallowing are common initial symptoms. If the disease is localized, surgical removal of the affected esophagus may offer the possibility of a cure. If the disease has spread, chemotherapy and radiotherapy are commonly used.
Ninety percent of cases of head and neck cancer (cancer of the mouth, nasal cavity, nasopharynx, throat and associated structures) are due to squamous cell carcinoma.
Cervical polyps often show no symptoms. Where there are symptoms, they include intermenstrual bleeding, abnormally heavy menstrual bleeding (menorrhagia), vaginal bleeding in post-menopausal women, bleeding after sex and thick white vaginal or yellowish discharge (leukorrhoea).
Clear-cell adenocarcinoma (CCA) of the vagina (or cervix) is a rare Adenocarcinoma (cancer) often linked to diethylstilbestrol (DES), a drug which was prescribed in the mistaken belief that it prevented miscarriage and ensured a healthy pregnancy.
They often cause no symptoms. Where they occur, symptoms include irregular menstrual bleeding, bleeding between menstrual periods, excessively heavy menstrual bleeding (menorrhagia), and vaginal bleeding after menopause. Bleeding from the blood vessels of the polyp contributes to an increase of blood loss during menstruation and blood "spotting" between menstrual periods, or after menopause. If the polyp protrudes through the cervix into the vagina, pain (dysmenorrhea) may result.
An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. They may have a large flat base (sessile) or be attached to the uterus by an elongated (pedunculated). Pedunculated polyps are more common than sessile ones. They range in size from a few millimeters to several centimeters. If pedunculated, they can protrude through the cervix into the vagina. Small blood vessels may be present, particularly in large polyps.
A cervical polyp is a common benign polyp or tumour on the surface of the cervical canal. They can cause irregular menstrual bleeding but often show no symptoms. Treatment consists of simple removal of the polyp and prognosis is generally good. About 1% of cervical polyps will show neoplastic change which may lead to cancer. They are most common in post-menarche, pre-menopausal women who have been pregnant.
