Ovarian cancer begins in one or both of the ovaries. When cells in the ovaries grow abnormally, they form into tumors that either can be non-cancerous (benign) or cancerous (malignant). If cancerous tumors are not detected early, they can spread from the ovaries to the fallopian tubes and pelvis as well as continue to spread to the abdominal area and other organs.
While treatment for early stage ovarian cancer is often successful there is a chance that the cancer can return. Recurrent ovarian cancer most often occurs when the original cancer was diagnosed at a later stage, typically stage III or IV.
