Women who have more moles may face a higher risk for developing breast cancer, a pair of new studies suggest.

The studies do not conclude that moles themselves cause breast cancer, but rather that moles are an indication of high hormone levels, which could elevate cancer risk.

One study analyzed 24 years of mole reports collected from more than 74,500 women enrolled in the Nurse's Health Study. The result: women who had 15 or more moles roughly 3mm in diameter or larger faced a 35% greater risk for breast cancer, compared with those who had none of these moles.

Further analysis pointed to high estrogen and testosterone levels as the possible cause.

And after sifting through 18 years of mole reports from nearly 90,000 women in France, a second study also unearthed preliminary evidence of a mole-breast cancer connection. However, the researchers stress that more work needs to be done before establishing how reliable mole spotting might be as a marker for breast cancer risk.
