Obesity is considered as a leading health problem in the United States. It is estimated that more than two-thirds of the US adults are overweight or obese. This condition is inextricably linked with numerous other health conditions such as heart disease, stroke, diabetes and respiratory problems.
According to the 2014 Cancer Progress Report from the American Association for Cancer Research (AACR), increased body weight is directly responsible for about 25% of cancer cases (which ranks second only to tobacco use). However, when this factor is combined with other related behaviors including a lack of physical activity and poor diet, its relative contribution rises to 33% of newly diagnosed cases in the US.
A new study reports that obese women have a 40 percent higher risk of developing cancer in their lifetime than thinner women. The study conducted by Cancer Research UK suggests that women who are overweight have about a one in four risk of developing a weight-related cancer in their lifetime, including gall bladder, womb, uterus, kidney, bowel, pancreas and esophagus, as well as post-menopausal breast cancers.
The researchers evaluated a group of 1000 obese women and found that nearly 274 were diagnosed with a body-weight-linked cancer in their lives as compared to a group of 100 healthy weight women, in which 194 diagnosed with cancer.
The results of the study indicate that excess body weight can significantly increase the risk of cancer in women. It emphasizes that increased body weight can result in greater production of hormones by the fat cells, especially estrogen, which is believed to fuel the proliferation of cancerous cells. In addition to lifestyle factors, cancer has other risk factors such as genes, family history, and environment. However, making meaning lifestyle changes to manage and control weight such as increased physical activity and balanced diet can reduce your potential risk of the disease.
