In Western countries, the main risk factors for the occurrence of head and neck cancer are alcohol and snuff , which together account for about 75% of the disease. Except for nasopharyngeal tumors, snuff and alcohol are at the origin of 90% of tumors.
However, the abandonment of such habits lowers the risk of a malignant tumor of the head and neck, according to a review of international work, which involved the Catalan Institute of Oncology, published in the journal International Journal of Epidemiology on last year.
The results of combined analysis showed a reduced risk of developing a tumor of head and neck after quitting in just 1-4 years. By contrast, only 40% profit is estimated on the risk of head and neck cancer after approximately 20 years to stop drinking alcohol. This may be due either to a longer time between the cessation of alcohol abuse and decreased risk of head and neck cancer, or a certain amount of irreversible damage associated with drinking that persist in time required .
