Obesity treatment and nutrition advice may be able to help reduce the chances of developing cancer.
According to a study conducted by New York University, obese adults who were obese from a young age, are at twice the risk of developing colon cancer compared to adults with a consistently normal weight.
Tam Fry, National Obesity Forum board member and chair for the Child Growth Foundation, said that "not enough people are aware that being overweight is a risk factor for cancer".
He added that the recession had resulted in an increased reliance on cheaper "junk food or fast food", which is "going to make it increasingly difficult for people to slim down".
According to Imperial College London, around one in 20 people in the UK will develop colon cancer in their lifetime, making it important for people to take control of their weight.
Mr Fry encouraged people to consider younger children as there was an increasingly common trend for children to be overweight.
