Risk Management & Treatment

Medications to lower endometrial cancer risk

Medications may lower the risk for endometrial and other cancers in women at high risk due to an inherited mutation, but data is very limited. More research is needed to help experts understand how well these medications work, and which patients may benefit most from their use. High-risk women who are considering medications to lower their risk for endometrial cancer should speak with their doctor to decide whether chemoprevention is their best option for managing their risk.


Progesterone

Often used as birth control, progesterone has been shown to lower the risk for ovarian cancer in both high-risk women and average-risk women. Some small studies also suggest that progesterone can lower the risk for endometrial cancer in high-risk women. 

Progesterone may be given as a pill, injection or through an Intrauterine Device (IUD). Progesterone can have side effects which vary widely based on how the medication is taken.  These side effects may include an increased risk for breast cancer and blood clots and weight gain.  


Aspirin

In people with Lynch syndrome, daily aspirin may decrease the risk for colon cancer. Researchers are studying whether aspirin lowers the risk for other cancers, including endometrial cancer. Aspirin can increase the risk for bleeding.
