Risk factors

Factors that can increase the risk that a liver hemangioma will be diagnosed include:

• Your age. A liver hemangioma can be diagnosed at any age, but it's most commonly diagnosed in people ages 30 to 50.
• Your sex. Women are more likely to be diagnosed with a liver hemangioma than are men.
• Pregnancy. Women who have been pregnant are more likely to be diagnosed with a liver hemangioma than women who have never been pregnant. It's believed the hormone estrogen, which rises during pregnancy, may play a role in liver hemangioma growth.
• Hormone replacement therapy. Women who use hormone replacement therapy for menopausal symptoms may be more likely to be diagnosed with a liver hemangioma than women who do not.
