People who underwent weight-loss surgery had a higher risk of colon cancer compared to the general population, reports a new study.

‘The drastic weight loss that occurs with successful bariatric surgery may raise your risk of colorectal cancer.
’

In the population-based study of 502,772 individuals with obesity from five Nordic countries, patients who underwent weight-loss surgery had a higher risk of colon cancer than the general population. 




This risk seemed to increase over time, and it exceeded the elevated risk of obese individuals without such surgery.
The association between weight loss surgery and rectal cancer was weaker, but it tended to increase with longer follow-up.
