Type 2 diabetes in post-menopausal women may increase chances of breast cancer.
According to a new study published in the British Journal of Cancer, women who have gone through menopause who also have Type 2 diabetes may have a 27% higher chance of getting breast cancer than other women.
The results stem from over 40 different studies by the International Prevention Research Institute (i-PRI), in Lyon, France. The study covered over 50,000 breast cancer patients from four different continents.
The researchers believe that there is a link between obesity and breast cancer, especially since being overweight is a risk factor for Type 2 diabetes.
Obesity alone is also a risk factor for breast cancer.
“We don’t yet know the mechanisms behind why type II diabetes might increase the risk of breast cancer. On the one hand, it’s thought that being overweight, often associated with type II diabetes, and the effect this has on hormone activity may be partly responsible for the processes that lead to cancer growth. But it’s also impossible to rule out that some factors related to diabetes may be involved in the process,” Professor Peter Boyle, president of i-PRI and lead author of the study told Counsel & Heal.
There was no evidence to support a link in pre-menopausal women, or those with type 1 diabetes.
