Is there a researched connection between CANCER and OBESITY?

The American Cancer Society has conducted the largest epidemiological study of obesity and site-specific malignancies. Through the last follow-up year, the study was successful in tracing 93 percent of the 1 million individuals in the long-term prospective study. Men who were 40% or more overweight had a 73% higher incidence of cancer. Women had as high as a 400% incidence of cancer occurring. Site-specific ratios are shown in the table below:
