Obesity Increases Risk of More Types of Cancers: Study

Researchers at the London School of Hygiene and Tropical Medicine revealed in their study what types of cancer can happen because of obesity.

For the research, five million people living in the UK were followed and their Body Mass Index (BMI) was monitored for a seven year period. After observing these people, researchers said that people who are overweight by 29lbs to 35lbs in comparison to an average adult had an increased risk of getting diagnosed with 10 types of cancer.

These cancers include uterus, gallbladder, kidney, liver, colon, ovarian, breast, thyroid, cervix, leukaemia and ovarian cancers.

Lead researcher, Dr. Krishnan Bhaskaran, said that rise in weight would not only make people diabetic and make them suffer from cardiovascular disease. But they will face greater risk of cancers also.

As per researchers, every year, more than 12,000 cases of these 10 cancers happen just because patients are obese or overweight. "It is well recognised that this is likely to cause more diabetes and cardiovascular disease. Our results show that if these trends continue, we can also expect to see substantially more cancers as a result", affirmed Dr. Bhaskaran.

Researchers said every 5 kg/m² increase in BMI was associated with higher risk of cancers. Percentage increase of each type was found as uterus (62%), gallbladder (31%), kidney (25%), cervix (10%), thyroid (9%) and leukemia (9%).

Higher BMI is associated with liver cancer (19%), colon cancer (10%), ovarian cancer (9%) and post-menopausal breast cancer (5%).

Tom Stansfeld, Health information officer at Cancer Research UK, was of the view that the large-scale study has strengthened the link between different types of cancer and obesity.
