Ovarian cancer is deemed to be the most deadly gynaecological cancer and is the fifth leading cause of cancer related deaths is the United States. Claiming close to some 15,000 lives each year, it is one form of cancer difficult to recognize because it displays no symptoms till it has advanced to a very high level. Ovarian cancer stages are dependent on the size and spread of the tumor inside the body. The further treatment of ovarian cancer is dependent on which stage it has progressed to. To classify stages, doctors take help of a simple rating system from 1 to 4. Stage I is the lowest on scale whereas Stage IV is close to being fatal and is the highest on the scale. Other than that, there are also borderline tumors.

A borderline tumor consists of low grade cancerous cells which have just started growing and multiplying. These have not yet affected the ovary in any way by growing into or damaging the ovarian tissue around them. This is not considered to be a bonafide ovarian cancer stage but is still treated as one with surgery. Stage I of the disease means that it has spread to the ovaries. This may be limited to one ovary or could be present in both ovaries. A further form of stage I shows up if the cancer has spread to the surface of the ovary or found inside of the abdomen during surgery. For stage I of ovarian cancer, surgery is the most effective way to dealing with it and preventing any sort of recurrence.

Ovarian cancer stage II usually means that the cancerous cells have spread from the ovary to the fallopian tube and/or uterus. A further form of stage II occurs when the cancer moves on to the pelvic region and cancerous tissue is seen in the rectum and bladder of the body as well. After which we come to stage III, where the cancer has definitely spread from the ovary to the abdominal region and can also be seen in the lymph nodes around the womb, crotch region and the upper part of the abdomen. The growths start becoming larger in size, measuring close to 2 cm and above, present in the lining of the abdominal cavity and causing many abdominal problems. These two stages usually call for chemotherapy to supplement the surgery done to remove as much cancer as possible from the body.

At the top is the ovarian cancer stage IV. This is the last stage of growth and often fatal for the patient. Survival rates at this point of treatment are pretty low and life expectancy after recovery is not very high. The treatment itself for this stage can be quite risky, especially for elderly women. At this stage, the cancer has spread from the ovaries and the abdomen to other parts of the body like the liver and lungs. After reaching here, radiation therapy is the best treatment available for the patients but is very dangerous for the elderly. A combination of surgery, chemotherapy and radiation is used at this point, often enough effectively.
