A new study presented at the European Congress on Obesity in Istanbul, Turkey, suggests that gaining weight in adulthood significantly increases the risk of certain cancers. The research, which analyzed body weight trajectories from ages 17 to 60,found that men who gained the most weight had a 2.67-times higher risk of liver cancer and a 2.25-times higher risk of esophageal cancer compared to those who gained the least.. Women who gained the most weight faced a 3.78-times higher risk of endometrial cancer.

Weight Gain Patterns and Cancer Risk

The study, which examined data from over 600,000 men and women, found that steeper weight gain over four decades was associated with higher rates of any canecr as well as many types of specific cancers. Men who put on the most weight and women who piled on the most pounds faced a heightened risk of various cancers.. Among men, associations per 0.5kg weight increase were stronger for early adulthood weight gain.

The Importance of Maintaining a Stable Weight

The findings highlight the importance of maintaining a stable, healthy weight throughout adult life.. Being overweight at the start of the study, aged 17, was also associated with a higher risk of several cancer types. Researchers emphasize that avoiding middle-age spread and post-menopausal weight gain is crucial if people want to keep their risk of the disease low.

Specific Cancer Risks by Gender

The study found that men who gained the most weight were at a 2.67-times higher risk of liver cancer and a 2.25-times higher risk of esophageal cancer compared with those who gaained the least. Women who piled on the most pounds faced a 3.78-times higher risk of endometrial cancer. These findings underscore the significant impact of weight gain on cancer risk,particularly for specific types of cancer.

Implications for Public Health

The study's results have important implications for public health. The findings suggest that maintaining a stable weight throughout adulthood could be a key factor in reducing the risk of cancer. this highlights the need for public health campaigns that promote healthy weight management and lifestyle choices to reduce the burden of cancer.
