Cancer develops when cells in a part of the body (in this case the ovary) begins to grow out of control. Although there are many kinds of cancer, they all start because of out-of-control growth of abnormal cells.
Normally, cells in your body divide, and form new cells to replace worn out or dying cells and to repair injuries. Because cancer cells continue to grow and divide, they are different from normal cells. Instead of dying, they outlive normal cells and continue to create new abnormal cells forming a tumor. Tumors can put pressure on other organs lying near the ovaries.
Cancer cells sometimes can travel to other parts of the body where they begin to grow and replace normal tissue. This process, called metastasis, occurs as the cancer cells move into the bloodstream or lymph vessels of our body. Cancer cells that spread from other organ sites (such as breast or colon) to the ovary are not considered ovarian cancer
There are many types of tumors that can start in the ovaries. Some are benign or noncancerous, and the patient can be cured by surgically removing one ovary or the part of the ovary containing the tumor. Some are malignant or cancerous. The treatment options and the outcome for the patient depends on the type of Ovarian Cancer and how far it has spread before it is diagnosed.
