What is the effect of factors that suppress ovulation on ovarian cancer risk?

Suppressing ovulation is associated with a decreased risk of developing ovarian cancer. This relationship stems from several biological mechanisms and epidemiological findings.

Firstly, repeated ovulation is thought to cause damage to the ovarian surface epithelium, which can lead to mutations and ultimately cancer. Each time an ovum is released, the process of ovulation involves the rupture of the follicle, which introduces the potential for cellular damage. By suppressing ovulation, factors such as hormonal contraceptives or conditions like pregnancy, breastfeeding, and using certain medications can significantly reduce the number of times this process occurs.

Moreover, hormonal contraceptives, especially those that contain a combination of estrogen and progestin, have been shown in numerous studies to provide protective effects against ovarian cancer. These contraceptives work by inhibiting ovulation and helping maintain the ovarian epithelium in a more stable state, thus reducing the risk of malignant transformation.

Additionally, a reduced frequency of ovulation correlates with decreased estrogen exposure, which can further decrease the risk of developing hormone-related cancers, including ovarian cancer.

In conclusion, factors that suppress ovulation play a critical role in lowering the risk of ovarian cancer, aligning with the assertion that such factors lead to a
