Cancer is one of the most common, feared and dangerous diseases of the 21st century, and so is obesity – although doctors knew already that there is a strong correlation between the two, a recent study comes to support the fact that cancer and obesity are very strongly linked. The percentage of obese adults and children has increased markedly over the past couple of decades, and this condition is now associated with increased risks for different types of cancer, such as that of the endometrium, breast, esophagus, kidney, pancreas, gallbladder, thyroid as well as cancer of the rectum and the colon. In addition to the fact that obese people are exposed to these types of cancer, they are also at high risk for other dangerous conditions such as stroke, high blood pressure, diabetes as well as coronary heart disease, amongst other chronic and potentially fatal diseases.
A Brief Overview Of The Relationship Between Cancer And Obesity
As mentioned above, obesity is associated with an increased risk for a variety of different types of cancer, and numerous studies have been conducted over the years which revealed the fact that approximately 4% of the cases of cancer occurring in men were related to obesity, and 7% of the cancers in women were due to the same condition. The exact percentages varied greatly from one type of cancer to another, but the same studies have revealed that for some cancers, such as the esophageal adenocarcinoma and the endometrial cancer, approximately 40% of the sufferers were overweight.
It is important to mention, however, that there are several potential explanations for the association of obesity with an increased risk for certain types of cancer, one of them being the fact that fat tissue is known to produce an excess amount of estrogen, which is known to be one of the primary culprits behind certain types of cancer such as endometrial or breast cancer, which occur in women. In addition to this, another potential explanation might be the fact that people who are overweight often experience increased levels of insulin in their bloodstream, which is known to develop certain tumors. Also, it is known that fat cells produce a type of hormones medically known as adipokines, which can inhibit or stimulate the growth of cells.
