Healthy lifestyles can benefit people with cancer, reducing recurrence and increasing long-term survival. But that knowledge alone is not enough to make cancer patients start exercising, and stop smoking and drinking, researchers report in the British Journal of Cancer. The study included 5,146 adults from the English Longitudinal Study of Ageing, and showed that the 433 who got cancer did not adopt healthier habits after diagnosis. Instead, they smoked and drank as much as those without cancer, and exercised even less. The researchers call for figuring out how to help cancer patients make lifestyle changes that can protect their health.
