People who are highly addicted to tobacco are at a higher risk of developing kidney cancer, particularly the more aggressive ones.

A review of 845 patients with kidney cancer who had already undergone surgery showed that smokers were at a 60 percent higher risk of suffering from advanced forms of the cancer.

According to the findings, 28.7 percent of current smokers and 29.3 percent of former smokers suffer from advanced form of the disease, which involves the lymph nodes or is spread in the body.

On the other hand, only 20.2 percent of patients who had never smoked are diagnosed with aggressive kidney cancer, researchers wrote in the Journal of Clinical Oncology.

The findings seem to be important as only 8 percent of patients with the most severe form of renal cancer survive five years while 70 percent of people with early-stage kidney cancer live for at least five years.

Researchers say the difference noted between the number of current and former smokers who are diagnosed with invasive kidney cancer suggests that quitting the habit may lower the risk.

"It can't bring you down to the risk of a nonsmoker, but it can get you almost there," said senior researcher Thomas J. Polascik.

Scientists concluded that the more cigarettes patients smoke, the higher would be their risk of being diagnosed with the disease.
