A new study was able to weed out gene-related risk factors for breast cancer (like BRAC1 and BRAC2) and provide the first clear data on the precise risk that obesity poses to women for breast cancer.

The study found that gaining 34 pounds anytime after the age of twenty increased the risk of breast cancer by 68%.  However, the study also showed that gaining 22 pounds after the age of thirty or gaining 12 pounds after the age of forty doubled the risk for breast cancer.

This points out that the older a woman is the less tolerance for inflammation related to the process of gaining weight she has.  It is very clear that breast cancer risk increases as problems of leptin resistance, insulin resistance, and IGF-1 malfunction combine with the inflammation of obesity. 
This study shows that the process of gaining weight is itself cancer causing.  In other words, if a woman gained 15 pounds when she was twenty-five and did not gain weight after that she would ha no increased risk.  However, if she maintained normal weight until she were forty and then gained the same 15 pounds, her risk for breast cancer doubles.

The moral of the story is that there is less margin for error the older we get.
