In women and men, breast and colorecta cancers are the most common obesity related cancers, revealed study.

How Does Obesity Cause Cancer
A 2019 study found that obesity related cancers accounted for nearly 4 percent of the global burden of cancers, Thangalvadi said.‘Women with severe obesity face cancers related to their reproductive organs like endometrial (4-7 times the risk compared to non-obese women), breast cancer (1.5 times) and ovarian cancer (1.1 times).’

As per Unicef's World Obesity Atlas 2022, India is predicted to have 2.7 crore children with obesity by 2030, he said. 




Thangalvadi said: "There are many ways in which obesity can increase the risk of cancer. Fat tissue in the human body releases excess levels of oestrogen, which in women leads to an increased risk of breast, endometrial, and ovarian cancer. High levels of insulin and insulin-like growth factor (IGF-1) in obese people increases risk of colorectal, kidney and prostate cancer. Obesity also leads to chronic inflammation and oxidative stress on tissues, further increasing the risk of cancer."
