Obesity and Cancer Relationship

Society in general may ask, what is the relationship of obesity with cancer? Is not that cancer patients tend to be thin? In 2001, experts concluded that colon cancer, breast (postmenopausal), endometrium, kidney, and esophagus, associated with obesity. Obesity and low physical activity causes approximately 25 to 30% of cancers such as colon cancer, breast (postmenopausal), endometrium, kidney and esophagus cancer.

Research conducted in the United States in patients over 16 years and non-Smokers, clearly shows that both men and women who are more obese at the beginning of the study (with the examination-IMT), have a higher risk of cancer. In this study, an increased risk of cancers such as kidney and uterus in women and liver cancer in men was most striking. Results from another study claimed that obesity is the number-two cause of cancer after smoking in the United States.
In the world, the increasing incidence of obesity and smoking is reduced, so that it is estimated that obesity one next decade will be the first risk factor for cancer in the United States. The results of this study was presented by the American Institute for Cancer Research and the World Cancer Research Fund International, with the theme: Food, Nutrition, Physical Activity, and the Prevention of Cancer: A Global Perspective. Now the estimated two thirds of the population in America are overweight.
Worldwide, cancer incidence increased faster than population growth. Although it is known that obesity increased the incidence of cancer, but kuantistas risk and increased risk of cancer which still needs further evaluation. The American Institute for Cancer Research and the World Cancer Research Fund International has gathered its members to evaluate the risk of cancer. The data discussed are the data from the 7000 study have been published.
Results of the review undertaken:
• Obesity significantly increases the risk of 6 Janis cancers: colon, kidney, pancreas, eosofagus, as well as endometrial and breast cancer in postmenopausal women.
• Increasing the number of pounds of body weight or excess fat increases the risk of cancer.
• Increased consumption of red meat increase cancer risk by 15%.
• Increased consumption of processed meats increase colorectal cancer risk. Associated with these results, the researchers make recommendations for the prevention of cancer (associated with weight loss):
• Try to be in the range of normal weight, (thin as possible).
• Consumption of foods derived from plants (fruits, vegetables, rice, and peas).
• Avoid red meat consumption of 18 ounces per week.
• Avoid consumption of processed meats as much as possible.
• Make physical activity as much as possible.
• Fixed meet nutritional needs through food.
• Consumption of no-calorie foods, like sweet drinks should be limited
• Restriction of alcohol consumption
• Patients who have successfully recovered from cancer should follow these recommendations. Added that obesity increases the risk of gallstone formation, and the presence of gallstones is increased risk of gallbladder cancer, which is expected to occur from supersaturasi cholesterol. Obesity affects circulating levels of hormones such as insulin, insulin-like growth factors and estrogen, which will create circumstances that promote carcinogenesis and reduces apoptosis. This stimulates the body's inflammatory response which will lead to the onset and progression of some cancers.
Several other studies showed an increased incidence of non-Hodgkin's lymphoma, leukemia and multiple myeloma in obese patients. Even in some reports, the relationship of obesity with cancers was expressed bermakan statistically. It is estimated that this occurs because obesity causes inflammation and pathological changes in the immune response, in which both of these factors will affect the function of lymphoid and hemapoetik cell function.
Experts say that doctors need to directly handle the excess weight found in patients, even if only seen a slight increase weight. With obese patients and overweight, doctors need to talk about diet, physical activity and sport. Every person money obese and overweight are encouraged to discuss with a doctor associated with weight and physical activity plan that will be undertaken to reduce cancer risk.
• In the future, obesity is likely to be the main cause of cancer.
• Obesity, lack of activity can increase your risk of cancer.
• Doctors need to perform preventive actions, in this case dealing with the excess weight in obese and overweight patients and discussion with patients about diet and physical activity needs to be done to reduce the risk of cancer.
