Cancer treatment is likely to be more effective in patients with good health habits, a recent study has indicated.
The research, which will be published in the September 1st issue of Cancer, revealed that older cancer survivors are being hampered by their unhealthy lifestyle.
Over half the 11 million cancer survivors in the United States are over the age of 65 and the study found their diet and exercise lacking.
Dr Mosher commented: "Our findings point to the potential negative impact of obesity and the positive effect of regular exercise and a healthy diet on physical quality of life outcomes among older, long-term cancer survivors.
"Only randomised clinical trials, however, can reveal whether lifestyle modification improves older, long-term cancer survivors' physical outcomes."
Figures released by Cancer Research UK earlier this month (July 10th) have found that death from the most common forms of cancers are at their lowest for nearly 40 years.
