Ovarian Cancer Explained 2

Stages of Ovarian Cancer

The initial surgery for ovarian cancer also helps determine how far the cancer has spread, described by the following stages:
Stage I: Confined to one or both ovaries
Stage II: Spread to the uterus or other nearby organs
Stage III: Spread to the lymph nodes or abdominal lining
Stage IV: Spread to distant organs, such as the lungs or liver

Types of Ovarian Cancer

The vast majority of ovarian cancers are epithelial ovarian carcinomas. These are malignant tumors that form from cells on the surface of the ovary. Some epithelial tumors are not clearly cancerous. These are known as tumors of low malignant potential (LMP). LMP tumors grow more slowly and are less dangerous than other forms of ovarian cancer.

Ovarian Cancer Survival Rates

Ovarian cancer can be a frightening diagnosis, with five-year relative survival rates that range from 89% to 18% for epithelial ovarian cancer, depending on the stage when the cancer was found. But keep in mind that these odds are based on women diagnosed from 1988 to 2001. The treatments and outlook may be better for people diagnosed today. For LMP tumors, the five-year relative survival rates range from 99% to 77%.

Ovarian Cancer Surgery

Surgery is used to diagnose ovarian cancer and determine its stage, but it is also the first phase of treatment. The goal is to remove as much of the cancer as possible. This may include a single ovary and nearby tissue in stage I. In more advanced stages, it may be necessary to remove both ovaries, along with the uterus and surrounding tissues.

Chemotherapy

In all stages of ovarian cancer, chemotherapy is usually given after surgery. This phase of treatment uses drugs to target and kill any remaining cancer in the body. The drugs may be given by mouth, through an IV, or directly into the belly (intraperitoneal chemotherapy.) Women with LMP tumors usually don't need chemo unless the tumors grow back after surgery.
medical conditions, including osteoporosis. It's vital that women have regular follow-up care after being treated for ovarian cancer.

Risk Reducer: Pregnancy

Women who have biological children are less likely to get ovarian cancer than women who have never given birth. The risk appears to decrease with every pregnancy, and breastfeeding may offer added protection.

Risk Reducer: 'The Pill'

Ovarian cancer is also less common in women who have taken birth control pills. Women who have used the pill for at least five years have about half the risk of women who never took the pill. Like pregnancy, birth control pills prevent ovulation. Some researchers think ovulating less often may protect against ovarian cancer.

Risk Reducer: Tubal Ligation

Getting your tubes tied, formally known as tubal ligation, may offer some protection against ovarian cancer. The same goes for having a hysterectomy -- removing the uterus while leaving the ovaries intact.

Risk Reducer: Removing the Ovaries

For women with genetic mutations that put them at high risk for ovarian cancer, removing the ovaries is an option. This can also be considered in women over 40 getting a hysterectomy.

Risk Reducer: Low-Fat Diet

While there is no definitive diet to prevent ovarian cancer, there is evidence that what you eat can make a difference. In one recent study, women who stuck to a low-fat diet for at least four years were less likely to develop ovarian cancer. Some researchers report the cancer is also less common in women who eat a lot of vegetables, but more studies are needed.
