Two studies published in June this year, in the journal PLOS Medicine linked moles to breast cancer.
According to researchers at Harvard and Indiana University who followed 74,523 women for 24 years, found that women with 15 or more moles had an 11.4% higher breast cancer risk, compared to 8.48% for women without any.
Another research done by the French Institute of Health and Medical Research (INSERM), studied 89,902 women for 18 years, and found that women with the highest number of moles had a 13% higher chance of developing breast cancer than women who didn’t have any moles.
But before you start counting the moles on your body, read on.
Researchers in both studies state that the mole-related risk disappeared after they considered factors like hormones or family history of breast cancer. What this means is that the mole-related risk only increase if a woman already have an existing risk factor e.g. a family member had breast cancer.
Take note, however, the studies’ results don’t mean that moles cause breast cancer. Moles don’t cause breast cancer. Moles appear to be an indicator for genetic or hormonal factors that may potentially cause breast cancer.
So if you have at risk for breast cancer, and also have many beauty marks on your body, it is definitely wise to be extra observant for unusual lumps in your breasts and to go for regular screening.
