Cervical cancer occurs when abnormal cells on the cervix grow out of control. Most cervical cancer is caused by HPV, which can be contracted through sexual contact. Symptoms may include abnormal bleeding or discharge. Cervical cancer is diagnosed through a Pap test and further tests if abnormalities are found. Treatment options include hysterectomy, radiation, chemotherapy, or removal of lymph nodes and ovaries. Regular Pap tests are important for early detection and prevention.
