Obesity causes 100,000 US cancers every year: study

The American Institute for Cancer Research has recently reported that in US obesity causes more than 100,000 incidents of cancer. Scientists for a long time had a vague opinion that there is a link between obesity and certain types of cancer, but this study is the first in series which made it clear that there is a link between obesity and certain types of cancer. Still the accurate cause or link is not known, but there are indications that suggest that fat tissue may produce heightened levels of sex hormones which spur cancer growth. Government backed Centers for Disease Control has reported that 34 percent of American adults aged 20 and over are obese. According to Laurence Kolonel of the Cancer Research Center of Hawaii "It's clearer than ever that obesity's impact is felt before, during and after cancer, it increases risk, makes treatment more difficult and shortens survival”.

It is a fact that obesity develops gradually and there are several reasons behind it like poor diet and sedentary lifestyle. It does not just happen overnight. Overconsumption is the root cause of the problem, eating large calories and fast-food items along with higher soft drink consumption in place of fruits and vegetables could be the leading cause of obesity. Did you know that alcohol is also full of calories and heavy drinkers are often obese? Bad eating habits like eating while watching television programs, lack of physical activities, computer games, surfing the net for longer hours while sitting at one place are some of the reasons for becoming obese in the long run. While Drugs like Insulin, Oral contraceptive pills, Group, Steroids also helps in gaining weight.

How to control obesity?
Regular and controlled exercise helps in checking obesity and pursuing 20 to 60 minutes of aerobic activity or walking three to five days a week, swimming, cycling, aerobics, activities like washing, climbing stairs, jogging can help control the obesity. Correcting behaviours’ like overindulgence in food and alcohol also helps in controlling this habit. You can’t lose weight even if you are engaging in physical activities unless you reduce the intake of fat items in your diet. If a person is under depression it is suggested to control it as well because of which a person tends to eat more get obese. Did you know, when we decrease the intake of calorie everyday we loose about 1 pound a week?

If you are reluctant to reduce your weight it is advised that eat less and exercise more. In the absence of this equilibrium you tend to weight loss in excess or gain weight in excess.
