Obesity and its associated diseases decrease the body's defenses, so that people with this type of problems are more likely to develop precancerous growths and tumors. In addition, they have more complications following a cancer treatment. Overweight women have a higher risk of having gynaecological cancer.
Expert: Dr. Enrique Oyarzún, gyneco-obstetrician at the University Clinic of the Andes.
Excess weight is a risk factor determinant in the development of some of these cancers in women, such as endometrial, breast, and ovary. The statistical data regarding the direct relationship between cancer and overweight women are alarming.
According to dr. Enrique Oyarzún, the probability of contracting endometrial cancer for a woman with overweight increases to four, and for an obese woman this figure rises to seven times, compared with the probability of that same woman with a normal weight.
Figures from epidemiological studies, show that there is a higher incidence among cancers of the breast and endometrium in women, associated with obesity. Women with overweight and its associated diseases, such as diabetes and hypertension, affected their immunological capacity and its defenses, so is more exposed to the likely development of precancerous lesions and tumors.
The cancer of breast and endometrium are malignant tumors that feed on estrogen. Overweight women produce an increased amount of estrogen, therefore, are more likely to have these tumors continue to grow.
Complications in therapy
The excess weight also affects the treatment of patients with cancer, because it hinders the effectiveness and outcomes of cancer therapy. Dr. Enrique Oyarzún explains: “Without a doubt that obesity also affects cancer therapy. The cornerstone of treatment of endometrial cancer is surgery, which is more complex and difficult in patients who are obese”.Also read: Condoms and sexually transmitted diseases (STDS)
In addition, it is more likely to have complications such as postoperative infections. The ob / gyn adds: “In the case of chemotherapy the administered dose has to be increased, because the drug has to distribute in a volume higher body. By having a higher dose, the possibility of complications may increase.”
