Smoking causes lung, throat and mouth cancer. It also weakens the body’s ability to fight with other forms of diseases.
According to the experts of the University of Leeds in England, patients with malignant melanoma, the most dangerous form of skin cancer and who also had a history of smoking cigarettes were 40 percent less likely to survive than non-smokers.
Julia Newton-Bishop who is the lead author has said that her team’s evidence suggests that smoking weakens the immune system, impairing patients’ ability to fight the disease.
She explained that “The immune system is like an orchestra, with multiple pieces.”
She also added, “This research suggests that smoking might disrupt how it works together in tune, allowing the musicians to continue playing but possibly in a more disorganized way.”
She added, “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. Based on these findings, stopping smoking should be strongly recommended for people diagnosed with melanoma.”
The team of her also believed that the immune system’s reaction to smoking is likely to be responsible as in a subset of 156 patients who had the strongest genetic indicators for immune cells, those who smoked were around four-and-a-half times less likely to have survived a decade after their diagnosis.
But they have not found the chemicals contained in cigarettes responsible.
700 people with melanomas, were covered under the study and was funded and published by U.K. charity Cancer Research. Head of health information at the organization Dr Julie Sharp said that this is another reason that’s why those who do smoke should try and quit smoking as soon as possible.
