BMI as one of the predisposing factors in breast cancerCreated by:
Body mass index (BMI) is a measure used to define body weight status (normal, overweight and obese). It includes a measure of height and weight, so it is a better comparison of body weight status than weight alone.
Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include: female sex, obesity, lack of physical exercise, drinking alcohol, hormone replacement therapy during menopause, ionizing radiation, early age at first menstruation, having children late or not at all, older age, and family history.
There are many studies conducted linking BMI to breast cancer risk. Gaining weight in adulthood appears to increase the risk of breast cancer before and after menopause. One large study found that women who gained about 20 pounds after age 18 had a 15 percent higher risk of breast cancer compared to women who gained little or no weight. Women who gained 55 pounds or more had a 45 percent higher risk.
