What is Ovarian cancer

Ovarian cancer is a malignancy that begins in the ovaries, the reproductive glands responsible for producing eggs and hormones. While it is often detected at an advanced stage due to subtle symptoms, it is a complex condition that can be managed through a combination of surgery, chemotherapy, and targeted therapies.



What exactly is ovarian cancer?


Ovarian cancer occurs when abnormal cells in the ovary begin to divide and grow uncontrollably, forming a tumor. These tumors can disrupt the function of the reproductive system and, if left untreated, spread to the peritoneum (the lining of the abdomen) and other nearby organs. Because the ovaries are located deep within the pelvis, ovarian cancer is frequently asymptomatic in its early stages, which is why it is often referred to as a "silent" disease.



What are the main types of ovarian cancer?


There are several classifications of ovarian cancer based on the type of cell where the malignancy originates:



  • Epithelial tumors: The most common type, arising from the thin layer of tissue that covers the outside of the ovaries.

  • Germ cell tumors: These rare tumors originate from the cells that produce eggs.

  • Stromal tumors: These develop in the structural tissue cells that produce hormones.



Who is typically affected by ovarian cancer?


Ovarian cancer primarily affects biological women, and the risk increases significantly with age; the median age at diagnosis is approximately 63 years. While it is not as common as breast cancer, it is a significant health concern globally. It is estimated that a woman's lifetime risk of developing ovarian cancer is about 1 in 78. Genetic factors, such as mutations in the BRCA1 or BRCA2 genes, play a critical role, accounting for roughly 10% to 15% of all cases.



How does ovarian cancer differ from other pelvic conditions?


Unlike benign ovarian cysts or endometriosis, ovarian cancer involves the malignant transformation of cells that can metastasize. Currently, 60 people with ovarian cancer have joined the DiseaseMaps community to share their experiences, highlighting the importance of peer support in navigating the diagnostic and treatment journey.
