女性的三大生殖系统恶性肿瘤与原因:

Cervical cancer: The cancer is caused by several types of a virus called human papillomaviruses (HPV). HPV spreads through sexual contact. Most women's bodies are able to fight this infection. But sometimes the virus leads to cancer. You're at higher risk of cervical cancer if you smoke, have many children, have many sex partners, use birth control pills for a long time, or have HIV infection.

Endometrial cancer: Although the exact cause of endometrial cancer is unknown, increased levels of estrogen appear to have a role. Estrogen helps stimulate the buildup of the lining of the uterus.

Ovarian cancer: This cancer usually occurs in women over age 50 but can affect younger women. It causes more deaths than any other cancer of the female reproductive system and is the leading cause of death from gynecologic cancer in the developed world. Its cause is unknown.
