But is there a link between being obese and developing breast cancer? This article will let you know.
Obesity is a condition in which a person has an unhealthy amount or distribution of body fat. Obesity is an established risk factor for postmenopausal, but not premenopausal, development of breast cancer. Evidence for a positive association between obesity and breast cancer mortality is gradually increasing. Avoiding adult weight gain and maintaining a healthy body weight may contribute importantly to decreasing breast cancer risk and mortality, especially in postmenopausal women. Several possible mechanisms have been explained to show how obesity might increase the risks of some cancers. These include:
- Obese people often have chronic low-level inflammation, which can, over time, cause DNA damage that leads to cancer. Overweight individuals are more likely than normal-weight individuals to have conditions or disorders that are linked to or that cause chronic local inflammation and that are risk factors for certain cancers.
- Fat tissue (also called adipose tissue) produces excess amounts of estrogen, high levels of which have been associated with increased risks of breast, endometrial, ovarian, and some other cancers.

Many studies link BMI to breast cancer risk. However, BMI affects risk differently before and after menopause.
- Before menopause, being overweight or obese modestly decreases breast cancer risk.
- After menopause, being overweight or obese increases breast cancer risk.
Research from the Nurses' Health Study found women who lost weight and kept it off for 4 or more years after menopause had a 40% lower risk of breast cancer. Another study found that weight-loss surgery was associated with an 83% lower risk of breast cancer. Many studies have also discovered that exercise is a breast-healthy habit. As little as 75 to 150 minutes of brisk walking, each week, has been shown to lower-down risk. Ramping up your exercise routine even more may lower your breast cancer risk even further.
