Physical activity is associated with a reduced risk of esophageal cancer, according to a new study presented by Mayo Clinic researchers at the American College of Gastroenterologyâ€™s Annual Scientific Meeting, Oct. 11â€“16, in San Diego.
â€śAlthough the incidence of esophageal squamous cell cancer is declining worldwide, the incidence of esophageal adenocarcinoma has been rapidly rising. This increase may be partly attributable to the obesity epidemic,â€ť says Siddharth Singh, M.B.B.S., the studyâ€™s lead author and researcher atÂ Mayo Clinic.

In an analysis of four studies, researchers observed a 32 percent lower risk of esophageal adenocarcinoma in people who were physically active. The analysis also showed the overall risk of esophageal cancer was 19 percent lower among the most physically active people compared with the least physically active.
Esophageal cancer is the sixth most common cancer in men worldwide. Early detection and prevention are critical to survival because most patients do not survive the first year of diagnosis, and only 15 percent of patients survive more than five years.
