According to health experts from the University of NSW, regular consumption of alcohol and excessive weight gain are major factors in the development of breast cancer.
The scientists predicted that by 2030 excessive alcohol and weight gain will be responsible for about 30,000 cases of breast cancer.
Researchers found that drinking alcohol will contribute to 13 per cent of breast cancer cases in pre-menopausal women. They also predict obesity will contribute to another 13 per cent of future preventable cases.
The University of NSW study found that breast cancer risk increased with 1 standard drink per day while there have been other studies that found the risk increases with any amount of alcohol.
