Cervical cancer is the most common cancer killer of women in developing countries. It has a high incidence rate of 15-30 per 100,000 women. Risk factors include HPV, smoking, multiple sexual partners, long-term birth control pill use, and HIV. Precancerous changes can be detected by Pap smears and colposcopy, allowing treatment before the disease becomes invasive. Early symptoms may include abnormal bleeding, but it can also be asymptomatic. Treatment involves radical hysterectomy, radiation, and chemotherapy depending on the FIGO stage - from local tumor to distant metastasis. Screening and HPV vaccination can help prevent cervical cancer.
