Ovarian Cancer

Information about epithelial carcinoma, the most common form of ovarian cancer.

A malignant tumor that begins in the ovaries is called ovarian cancer. The most common type begins on the surface of the ovary and is known as epithelial carcinoma. Ovarian cancer that begins in the egg-producing cells (germ cell tumors) and cancer that begins in the supportive tissue surrounding the ovaries (stromal tumors) are far more rare and are not discussed in this article. The Cancer Information Service of the National Cancer Institute can provide information or suggest resources that deal with these less common types of ovarian cancer.

Ovarian cancer cells can break away from the ovary and spread to other tissues and organs in a process called shedding. When ovarian cancer sheds, it tends to seed (form new tumors) on the peritoneum (the large membrane that lines the abdomen) and on the diaphragm (the thin muscle that separates the chest from the abdomen). Fluid may collect in the abdomen. This condition is known as ascites. It may make a woman feel bloated, or her abdomen may look swollen.

Ovarian cancer cells can also enter the bloodstream or lymphatic system (the tissues and organs that produce and store cells that fight infection and disease). Once in the bloodstream or lymphatic system, the cancer cells can travel and form new tumors in other parts of the body.

Preparing for Treatment

Many people with cancer want to learn all they can about the disease and their treatment choices so they can take an active part in decisions about their medical care. When a person is diagnosed with cancer, shock and stress are natural reactions. These feelings may make it difficult to think of everything to ask the doctor. Often, it helps to make a list of questions. To help remember what the doctor says, patients may take notes or ask whether they may use a tape recorder. Some people also want to have a family member or friend with them when they talk to the doctor—to take part in the discussion, to take notes, or just to listen.

People do not need to ask all of their questions or remember all of the answers at one time. Questions may arise throughout the treatment process. Patients and caregivers may ask doctors, nurses, or other members of the health care team to explain things further or to provide more information.

These are some questions a patient may want to ask the doctor before treatment begins:

  • What is the diagnosis?
  • What is the stage of the disease?
  • What is the grade of the disease?
  • What are the treatment choices? Which do you recommend? Why?
  • What are the risks and possible side effects of each treatment?
  • What are the chances that the treatment will be successful?
  • What new treatments are being studied in clinical trials? Would a clinical trial be appropriate?
  • How long will treatment last?
  • Will treatment affect my normal activities? If so, for how long?
  • What is the treatment likely to cost?

Follow-up Care

Follow-up care after treatment for ovarian cancer is very important. Regular checkups generally include a physical exam, as well as a pelvic exam and Pap test. The doctor also may perform additional tests such as a chest x-ray, CT scan, urinalysis, complete blood count, and CA-125 assay.

In addition to having follow-up exams to check for the return of ovarian cancer, patients may also want to ask their doctor about checking them for other types of cancer. Women who have had ovarian cancer may be at increased risk of developing breast or colon cancer. In addition, treatment with certain anticancer drugs may increase the risk of second cancers, such as leukemia.
