“Women who smoke even 10 or fewer cigarettes a day increase their risks for colon cancer,” said lead researcher Dr. Inger Gram, a professor in the department of community medicine at the University of Tromso in Norway.
“Because colon cancer is such a common disease, even these moderate smoking accounts for many new cases,” she said. “A lot of colon cancer can be prevented if people don’t smoke — especially women.”
