General Information About Ovarian Low Malignant Potential Tumors



Ovarian low malignant potential tumor is a disease in which abnormal cells form in the tissue covering the ovary.

Ovarian low malignant potential tumors have abnormal cells that may become cancer, but usually do not. This disease usually remains in the ovary. When disease is found in one ovary, the other ovary should also be checked carefully for signs of disease.

The ovaries are a pair of organs in the female reproductive system. They are in the pelvis, one on each side of the uterus (the hollow, pear-shaped organ where a fetus grows). Each ovary is about the size and shape of an almond. The ovaries make eggs and female hormones.

Possible signs of ovarian low malignant potential tumor include pain or swelling in the abdomen.

Early ovarian low malignant potential tumor may not cause any symptoms. If you do have symptoms, they may include the following:

These symptoms may be caused by other conditions. If the symptoms get worse or do not go away on their own, check with your doctor.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

  • The stage of the disease (whether it affects part of the ovary, involves the whole ovary, or has spread to other places in the body).
  • What type of cells make up the tumor.
  • The size of the tumor.
  • The patient’s general health.

Patients with ovarian low malignant potential tumors have a good prognosis, especially when the tumor is found early.
