The pill and cancer.
The relation between oral contraceptives (OC) and cancer risk has been investigated extensively, mainly with reference to breast, female genital tract, liver cancer and cutaneous malignant melanoma, and will be summarized below. There is also some suggestion that OC use is related to other neoplasms, including a reduced risk of colorectal cancer among OC users, but the issue is still controversial and too preliminary to provide indications for informed contraception choice.
