A recent research shows that obesity, alcohol consumption and smoking increases the chances of developing second breast cancer in women who already fought it off once.
Earlier studies has already concluded that breast cancer survivors have greater chances of developing recurrent breast cancer than women without first breast cancer.
According to new study led by the researchers at Fred Hutchinson Cancer Research Center, it has found that obesity, increased alcohol consumption and smoking significantly raises the risk of second breast cancer among breast cancer survivors.
Obesity and alcohol increases the levels of circulating estrogen, which in turn fuel up the breast cancer growth. The link between smoking and breast cancer may be attributed to carcinogens in tobacco smoke.
