Watch your weight before 40, else face cancer risk

London: Researchers have found that being overweight before the age of 40 could increase the risk of various cancers in adults.
“Obesity is an established risk factor for several cancers. In this study, we have focused on the degree, timing, and duration of overweight and obesity in relation to cancer risk,” said study author Tone Bjorge, Professor at the University of Bergen in Norway.
For the findings, published in the International Journal of Epidemiology, the research team wanted to find out how adult overweight (BMI over 25) and obesity (BMI over 30) increase the risk of different types of cancer.
The researchers used data for 2,20,000 individuals from the Me-Can study, with participants from Norway, Sweden, and Austria.
Data from health examinations, including information on height and weight, were linked to data from national cancer registries.
According to the researchers, 27,881 individuals were diagnosed with cancer during follow-up, of which 9,761 (35 percent) were obesity-related.
