A new study showing smoking can hurt the immune system’s ability to fight off cancer.
The study found patients with malignant melanoma who were regular smokers in the past have a 40 percent lower chance of surviving than patients who haven’t smoked.
While the study does associate smoking with a decrease in the survival rate for cancer, it doesn’t directly link it as the cause for the drop.
According to a researcher of the study Julia Newton-Bishop stated:
The result is that smokers could still mount an immune response to try and destroy the melanoma, but it appears to have been less effective than in never-smokers, and smokers were less likely to survive their cancer.
The study was published Sunday in the journal Cancer Research.
