In a recent study, researchers from the Tel Aviv University in Israel have found that adolescents who are overweight are more likely to be at a risk of developing colon cancer as they become adults.
According to the study published in the journal Cancer, being overweight and obese was associated with 53 percent and 54 percent higher risk of colon cancer for men and women, respectively.
In addition to this obesity was associated with 71 percent increased risk of rectal cancer in men and more than a twofold increased risk in women.
Zohar Levi from Tel Aviv University said "This is a huge cohort with a minimum follow up for 10 years, and all individuals had measured Body Mass Index (BMI)."
For the study the researchers had analyzed 1,087,358 Jewish males and 707,212 Jewish females who underwent health examinations, including measures of BMI, at age 16 to 19 years (predominantly aged 17 years) between 1967 and 2002. The follow-up of the case was done till 2012.
During the study it was 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).
