Type 2 diabetes affects the risk of breast cancer

The presence of type 2 diabetes increases the risk of breast cancer in older women more than a quarter. This is the conclusion, researchers from the International Centre for Cancer Prevention in Lyon.

French scientists have found that being in postmenopausal women at 27% greater risk of becoming victims breast cancer If they already suffer from Type 2 diabetes . Among women with diabetes who have not reached menopause, the risk of cancer remains at the same level as that in healthy women

Note that the presence of type 1 diabetes, which usually develops from birth and is not related to an unhealthy lifestyle, did not increase the risk of   breast cancer   women of different age groups. These conclusions were based on the analysis of 40 different studies that examined 56,000 cases of the disease.

"We do not know exactly what the mechanism is the link Type 2 diabetes   and increased risk of breast cancer - said study author Professor Peter Boyle. - On the one hand, it can theoretically be overweight, which is observed in the majority of type 2 diabetics. It affects the activity of hormones that affect cancer cell growth. On the other hand, it is important to check and other factors associated with diabetes. They may also be involved in this process. "

Science has previously proven that obesity and simultaneously increases the risk of breast cancer, and type 2 diabetes. It remains to understand why diabetes increases the risk of cancer in older women is because younger amount of hormones in the blood is much higher.
