Ovarian Mass / Ovarian Tumor Symptoms & Causes

LIke ThisLIke ThisLIke ThisLIke ThisLIke This

In adolescence, ovarian cysts can develop in response to fluctuating levels of female sex hormones during the menstrual cycle. The cause of ovarian tumors in infants and children is unknown.

Symptoms of a mass on your daughter's ovaries may have no specific symptoms, or could depend on the size, location and type of growth. Your daughter may experience the following symptoms:

  • A feeling of pressure or fullness in the abdomen or pelvis
  • A firm, painless swelling in the lower abdomen
  • Frequent urination or retention of urine
  • Persistent abdominal pain
  • Nausea
  • Vomiting
  • Sometimes, ovarian cysts are painful if they cause the ovary to twist on its root, because blood is blocked from the ovary. In this situation, your daughter will likely experience severe abdominal pain and may vomit or pass out.

In girls younger than 8, an ovarian tumor or cyst may cause secretions of estrogen, producing symptoms such as:

  • Breast enlargement
  • Pubic hair
  • Vaginal discharge or bleeding
  • Abnormal menstrual bleeding
