What is the relationship between oral contraceptives and cancer?
Recent studies have determined that excess consumption of progesterone and estrogen can increase the risk of cancer cell growth, such as uterine cancer and breast cancer. These hormones stimulate the renewal and growth of cells in the endometrium, but these studies determined that synthetic versions of these hormones, used in contraceptive pills, can stimulate excessive cell production, increasing the risk of cancer cell growth.
The use of oral contraceptives has also increased the risk of human papilloma virus (HPV) infections, increasing the risk of cervical cancer. This virus is one of the main risk factors for cervical cancer, because it causes irreversible damage to the cells, stimulating the excessive proliferation of cells to try to repair the damage and increasing the risk of the growth of cancer cells.
