Research links levonorgestrel IUDs to breast cancer, but GP says the risk is small compared with benefits
A registry study found an excess breast cancer risk of 14 cases per 10,000 women.

In a letter published in JAMA, researchers from Denmark said levonorgestrel-releasing intrauterine systems (LNG-IUSs) were linked to an excess breast cancer risk of 14 cases per 10,000 women.
