Cancer linked to overweight and obesity include thyroid, liver, kidney, and ovarian cancer, constituting 40 per cent of cancers diagnosed in the US, according to the latest Vital Signs report by the CDC.
The study states that overall, the rate of new cancer cases has decreased since the 1990s, but a rise in overweight- and obesity-related cancers are likely slowing this progress.

The United States Cancer Statistics data shows that 55 per cent of all cancers diagnosed in women are overweight and obesity compared with only 24 per cent of cancers in men.
The difference is due to endometrial, ovarian, and post-menopausal breast cancer, which together make up 42 per cent of cases of obesity-related cancers. The report did not look at lifestyle factors, but the fact that women are less likely to use tobacco and alcohol makes the sharp burden for women-only overweight and obesity cancers especially confounding.
“The rates of obesity-related cancers, not including colorectal cancer, increased by seven per cent between 2005 and 2014,” said CDC director Brenda Fitzgerald.
She said by keeping fit and staying healthy would mean that we are all playing a role in cancer prevention.
A research conducted by the Ministry of Health in Kenya last year revealed that a large number of women in the country are obese. According to the data, 33 per cent of the women were found to be obese, which the study attributed to poor nutrition
