What type of secondary benefits can combined oral contraceptives provide beyond pregnancy prevention?

Combined oral contraceptives are known to offer several secondary benefits beyond their primary role of preventing pregnancy. One significant secondary benefit is the reduction in the risk of certain types of cancers, particularly ovarian and endometrial cancers. The hormones in these contraceptives help regulate the menstrual cycle and can lead to reduced endometrial lining buildup, which decreases the likelihood of developing endometrial cancer. Additionally, long-term use of combined oral contraceptives has been linked to a lower risk of ovarian cancer due to the suppression of ovarian activity and the potential for reduced ovulation.

This benefit is particularly important for patients who may have a family history of these cancers or for those seeking a long-term contraceptive option with added health benefits. While combined oral contraceptives can also help manage conditions like polycystic ovary syndrome (PCOS) and endometriosis, the cancer risk reduction is a well-documented and relevant aspect of their use.
