Researchers concluded that the cancers began with genetic mistakes occurring in cells in the fallopian tubes, and that the cancers developed within an average of 6.5 years. In some cancers, these types of mutations leading to the development of cancer may result from radiation or cancer-causing chemicals, but there is no evidence for this in ovarian cancer. Research has suggested that tests to identify acquired mutations in ovarian cancers, like the TP53 tumor suppressor gene or the HER2 oncogene, can help predict a woman's prognosis. We couldn’t do what we do without our volunteers and donors. In addition, these cells also attack surrounding cells and spread to other organs. There are many theories about the causes of ovarian cancer. Since both of these things reduce the number of times the ovary releases an egg (ovulation), some researchers think that there may be some relationship between ovulation and the risk of developing ovarian cancer.

[1-4] Cancer grows in the cell’s DNA through mutations that produce an unusual mass of cells which persists to survive as the healthy cells die. If you have a family history of cancers linked to these syndromes, such as breast and ovarian cancers, thyroid and ovarian cancer, and/or colorectal and endometrial (uterine) cancer, you might want to ask your doctor about genetic counseling and testing.
