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,...

The following are risk factors for ovarian cancer:

Family history of ovarian cancer

A woman whose mother or sister had ovarian cancer has an increased risk of ovarian cancer. A woman with two or more relatives with ovarian cancer also has an increased risk of ovarian cancer.

Inherited risk

The risk of ovarian cancer is increased in women who have inherited certain changes in the BRCA1, BRCA2, or other genes.

The risk of ovarian cancer is also increased in women who have certain inherited syndromes that include:

  • Familial site-specific ovarian cancer syndrome.
  • Familial breast/ovarian cancer syndrome.
  • Hereditary nonpolyposis colorectal cancer (HNPCC; Lynch syndrome).

Hormone replacement therapy

The use of estrogen -only hormone replacement therapy (HRT) after menopause is linked to a slightly increased risk of ovarian cancer in women who are taking HRT or have taken HRT within the past 3 years. The risk of ovarian cancer increases the longer a woman uses estrogen-only HRT. When hormone therapy is stopped, the risk of ovarian cancer decreases over time.

It is not clear whether there is an increased risk of ovarian cancer with the use of HRT that has both estrogen and progestin.


The use of talc may cause a small increase in the risk of ovarian cancer. Talcum powder dusted on the perineum (the area between the vagina and the anus) may reach the ovaries by entering the vagina.

Weight and height

Being overweight or obese during the teenage years, and gaining 40 or more pounds during adulthood is linked to an increased risk of ovarian cancer. Being obese is linked to an increased risk of death from ovarian cancer. Being tall (5'8" or taller) may also be linked to a slight increase in the risk of ovarian cancer.
