Smoking kills. It's hardly news to us. But if you've been struggling to stop and just can't find the motivation to do so, now there's another reason to stop smoking. A new study published in CANCER, a peer-reviewed journal of the American Cancer Society, has found that smoking not only causes lung cancer—if you smoke, you also have a greater chance of developing a more aggressive and deadly form of bladder cancer than non-smokers.
Researchers have long known that smoking is one of the most common
causes of bladder cancer
, but they've wondered whether it also affects how the disease progresses. A team led by Richard J. Cote, MD, of the University of Miami Miller School of Medicine, and Anirban Mitra, MD of the Keck School of Medicine of the University of Southern California, analysed bladder tumours and smoking history and found the answer ...
More aggressive bladder cancer if you smoke
The findings prove that the bladder cancers that developed in those who smoked intensely were more likely to be deadly than the bladder cancers that developed in those who never smoked, or who smoked less.
The study also revealed that changes in particular proteins are often present in bladder cancers that have become deadly. “We’ve identified a panel of nine molecular markers that can robustly and reproducibly predict bladder cancer prognosis independent of standard clinical criteria and smoking history,” said Mitra.
Bladder cancer isn’t just a ‘male thing’. The US National Institutes of Health website adds
that the proportion of bladder cancer due to smoking in women is now the same as for men—about 50%. So the more you smoke, the more intense the side effects will be. Kick the habit to avoid bladder cancer.
