A woman’s body is a complex structure that works in mysterious ways. Breast cancer affects 1 in 8 women in the United States.
Surprisingly, a woman’s body weight plays a major role in the risk of breast cancer before and after menopause.
Read on for more information regarding breast cancer and other interesting facts.
The Basics of Body Mass Index and Body Weight
Your BMI, or body mass index, is used to determine your body weight’s status, which ranges from normal, overweight, and obese. Included within the BMI is an individual’s height.
People 20 years of age and older or those who suffer from being obese, their risk BMI increases and the basic chart that is followed.
A BMI ranging between 18.5 to 24.9 is considered normal. 25.0 to 29.9 is deemed overweight. 30.0 or greater is considered overweight.
They’re All Connected
Many women are surprised to find out body weight, menopausal status, and the risk of developing breast cancer are all connected. Many studies you will find suggest a person’s BMI is linked to breast cancer.
A person’s BMI affects an individual before and after menopause differently. Before menopause, women who are overweight or suffer from being obese have a much lower risk of developing breast cancer.
After menopause occurs, women suffering from obesity or being overweight plays a significant role in breast cancer due to fat tissue.
Breast Cancer Risks Before and After Menopause
The Risk Before Menopause
Women who suffer from obesity or are overweight have a 21 to 39 percent lower risk of developing breast cancer. Before menopause, women who are slender have a much higher risk of developing breast cancer.
The Risk After Menopause
After menopause, women who are overweight or suffer from obesity have an increased risk of 31 to 59 percent of developing breast cancer. Women who are lean in this instance have a much lower risk of developing this form of cancer.
How is Body Weight a Contributing Factor for Breast Cancer After Menopause?
Fat tissue and the ovaries have a significant role in breast cancer. The ovaries produce estrogen for a woman’s body before menopause. After menopause occurs, the body’s estrogen supply derives from fat tissue and a decreased amount of estrogen is produced.
Looking at the situation from a glance.
Women who are overweight or obese have higher blood estrogen levels than women who are fit or slim due to aromatase. Aromatase is an enzyme that is found in fat tissue and changes androgens to estrogens. Androgens are created in the adrenal glands.
The increased estrogen levels are partially responsible for the increased risk of breast cancer in overweight women who are postmenopausal.
The Insulin Factor
Type two diabetes becomes a factor with women who are overweight because they have more insulin in their bodies than women who are not overweight or obese.
Women who are pre-menopausal in this situation do not reveal a clear link that justifies the link between breast cancer and insulin.
Breast Cancer and Gaining Weight
Weight gain has a negative impact on the risk of developing breast cancer before and after menopause.
One mass study revealed women, who after age 18 gained an estimated 20 pounds had more than a 14 percent higher risk than women who gained less weight or maintained their weight of developing breast cancer.
Breast Cancer and Losing Weight
It is suggested that women who are overweight or obese that lose weight lower their risk of developing breast cancer.
In recent studies, women who were overweight or obese who lost as little as four pounds and as much as 11 pounds decreased their risk of developing breast cancer by more than 20 percent.
Breast cancer is more involved than many people think. A woman can significantly decrease her chances of developing breast cancer by losing weight and maintaining a healthy weight before and after menopause becomes a factor.
