The most common ovarian tumors begin in the cells that cover the ovary. These tumors are called epithelial tumors. Tumors can also begin in germ cells (cells that form eggs) or stromal cells (cells that produce hormones and hold the ovary together). Many ovarian tumors are benign (not cancerous). If an ovarian tumor is cancerous, it is most likely a malignant epithelial tumor.

Ovary Anatomy

The number of cases of ovarian cancer has been decreasing over the past 20 years. In 2012, an estimated 22,000 women will be diagnosed with ovarian cancer in the United States. Less than 1 in 5 cases of ovarian cancer are diagnosed before the cancer has spread outside the ovary.

Treatment for ovarian cancer depends on the stage of the cancer, your age, if you plan to have children, and your overall health. Your personal treatment preference is also an important factor.

Chemotherapy can cause side effects

Chemotherapy stops or slows the growth of cancer cells. Often, cancer cells are fast growing. But chemo also damages healthy cells that divide quickly. These healthy cells can include cells in the bone marrow that make blood, cells in the lining of the gut and mouth, and hair cells. Damage to healthy cells is what causes many chemo side effects Here's how it works:

  • When chemo kills healthy blood cells, the result can be:
  • Chemo may damage healthy cells in the stomach. The chemo drugs then irritate these areas, which could result in nausea and vomiting. Chemotherapy drugs may also trigger signals in the brain that tell your body to vomit.
  • When chemo affects healthy cells surrounding hair follicles, the result can be hair loss. Hair loss is also known as alopecia.

Chemo can cause many other side effects, but the good news is that there are ways to manage them.

A Closer Look: Evelyn*
A retired school teacher, Evelyn has a history of stage III ovarian cancer. She begins to experience fatigue, bloating, and abdominal pain.
She has previously been through many rounds of chemo. Her cancer has been in remission for 6 years.
An exam and MRI find a nodule in her vagina. A biopsy is performed, which confirms her diagnosis.
Her doctor prescribes a chemo regimen for 5 days in a row over a 21-day cycle.
Because of her previous experience with chemo, Evelyn knows what, in general, to expect. But she has never had the chemo regimen her doctor prescribed before. She discusses side effects management with her doctor.
Her doctor and care team help her prepare to manage the chemo side effects.
