In a new study, a researcher from Tel Aviv University (Israel) has concluded that overweight adolescents are more likely to be at a risk of developing colon cancer as adults. The study which was published in the journal Cancer found that being overweight and obese was associated with 53 percent and 54 per cent higher risk of colon cancer for men and women, respectively.
Obesity associated with 71% increased risk of rectal cancer in men
According to the lead researcher, Zohar Levi from Tel Aviv University "Obesity was associated with 71 percent increased risk of rectal cancer in men and more than a twofold increased risk in women. This is a huge cohort with a minimum follow up for 10 years, and all individuals had measured Body Mass Index (BMI), not just reported or recalled,".
Study based on an old research
Researcher analysed information of an analysis, which was done till 2012. The analysis had information of 1,087,358 Jewish males and 707,212 Jewish females who underwent health examinations. The health check-ups including measures of BMI, were done at the age 16 to 19 years (predominantly aged 17 years) between 1967 and 2002. As a result they found that over a median follow up of 23 years, 2,967 new cases of colorectal cancer were identified, including 1,977 among men (1,403 colon, 574 rectum) and 990 among women (764 colon,226 rectum).
