How many years does it take for ovarian cancer to develop?

The formation time of ovarian cancer usually takes 5-20 years, and the specific time is related to individual differences, pathological types and other factors.

The development of ovarian cancer is a multi-stage progressive process. It may take 3-5 years to go from normal ovarian epithelial cells to precancerous lesions, at which time the cells have abnormal proliferation but are not yet invasive. It usually takes 2 to 5 years for precancerous lesions to develop into early-stage ovarian cancer, when the tumor is localized to the ovaries. It usually takes 3-10 years for early-stage ovarian cancer to progress to advanced stages. Cancer cells may break through the capsule and spread to the pelvis. High-risk ovarian cancer develops quickly and may complete the entire process within 5 years, while low-risk ovarian cancer may take more than 15 years. Some special types, such as borderline tumors, develop more slowly and can last up to 20 years.

It is recommended to have regular gynecological examinations, especially women with high-risk factors such as family history of ovarian cancer and BRCA gene mutations should increase the frequency of screening. Maintaining a healthy lifestyle, controlling weight, and avoiding long-term use of estrogen replacement therapy may help reduce the risk of ovarian cancer. If persistent symptoms such as abdominal distension, abdominal pain, and frequent urination occur, you should seek medical examination in time.
