What is the most common cancer in nulliparous and subfertile women?

The most common cancer in nulliparous and subfertile women is ovarian cancer. This group of women experiences unique reproductive challenges that have been linked to an increased risk of developing certain types of gynecologic cancers. Nulliparity (having never given birth) and subfertility can lead to hormonal changes and other biological factors that contribute to the development of ovarian cancer.

Ovarian cancer is often referred to as a "silent killer" because it can be difficult to detect in its early stages, and symptoms may not manifest until the disease has progressed. It is essential for nulliparous and subfertile women to be aware of the risk factors associated with ovarian cancer, as well as to engage in regular health screenings as advised by healthcare providers.

Identifying this information can help facilitate early detection and anticipatory guidance for women in these demographics. Other types of cancer listed, although significant, do not have the same level of association with nulliparity and subfertility as ovarian cancer does.
