Exploring the Link Between Hormones and Ovarian Cancer: Implications for Risk Assessment.

Ovarian cancer is the fifth most common cause of cancer-related deaths among women in the developed world. The disease occurs when abnormal cells in the ovary begin to grow and divide uncontrollably, forming a tumor. While the exact causes of ovarian cancer are unknown, evidence suggests that hormonal imbalances may play a role in the development of the disease. In this article, we will explore the link between hormones and ovarian cancer and discuss the implications of this connection for risk assessment.

The Role of Hormones in Ovarian Cancer

The ovaries are part of the reproductive system and are responsible for producing hormones such as estrogen and progesterone. These hormones play a crucial role in regulating the menstrual cycle and maintaining the health of the female reproductive system.

However, when there is an excess of these hormones or a hormonal imbalance, the risk of developing ovarian cancer increases. For example, women who start menstruating at an early age or experience menopause at a late age are at a higher risk of developing ovarian cancer because they are exposed to more estrogen over their lifetime.

Other factors that can contribute to hormonal imbalances and increase the risk of ovarian cancer include long-term use of hormone replacement therapy, obesity, and polycystic ovarian syndrome (PCOS).

Implications for Risk Assessment

Understanding the link between hormones and ovarian cancer has important implications for risk assessment. While there is no way to completely eliminate the risk of developing ovarian cancer, identifying individuals who are at a higher risk due to hormonal factors can help inform screening and prevention strategies.

For example, women who have a family history of ovarian cancer or carry certain genetic mutations (such as BRCA1 and BRCA2) that increase the risk of the disease may be offered more frequent screenings, such as pelvic exams, ultrasound, or blood tests that measure levels of the tumor marker CA-125.

Additionally, women who are at a higher risk of ovarian cancer may be advised to make lifestyle changes that can help regulate hormone levels and reduce the risk of the disease. This may include maintaining a healthy weight through diet and exercise, avoiding hormone replacement therapy, and discussing options for hormonal birth control with a healthcare provider.


Hormonal imbalances can play a significant role in the development of ovarian cancer. Understanding this link can help inform risk assessment, screening, and prevention strategies for women who are at a higher risk of the disease. By taking steps to regulate hormone levels and reduce our exposure to risk factors, we can work towards reducing the incidence and impact of ovarian cancer.
