Alcohol and tobacco
Around 75% of cases are caused by alcohol and tobaccouse. Tobacco smoking is one of the main risk factors for head and neck cancer. A major carcinogenic compound in tobacco smoke is acrylonitrile. Acrylonitrile appears to indirectly cause DNA damage by increasing oxidative stress, leading to increased levels of 8-oxo-2'-deoxyguanosine (8-oxo-dG) and formamidopyrimidine in DNA. (see image). Both 8-oxo-dG and formamidopyrimidine are mutagenic. DNA glycosylase NEIL1 prevents mutagenesis by 8-oxo...
Diet
In one study, excessive consumption of eggs, processed meats, and red meat was associated with increased rates of cancer of the head and neck, while consumption of raw and cooked vegetables seemed to be protective. Vitamin E was not found to prevent the development of leukoplakia, the white plaques that are the precursor for carcinomas of the mucosal surfaces, in adult smokers.Another study examined a combination of Vitamin E and beta carotene in smokers with early-stage cancer of the orophar...

When diagnosed early, oral, head, and neck cancers can be treated more easily, and the chances of survival increase tremendously.As of 2017, it was not...
Improvements in diagnosis and local management, as well as targeted therapy, have led to improvements in quality of life and survival for people with head and neck cancer. After a histologic diagnosis has been established and tumor extent determined, such as with the use of PET-CT, the selection of appropriate treatment for a specific cancer depend...
Although early-stage head and neck cancers (especially laryngeal and oral cavity) have high cure rates, up to 50% of people with head and neck cancer present with advanced disease.Cure rates decrease in locally advanced cases, whose probability of cure is inversely related to tumor size and even more so to the extent of regional node involvement.[c...
The number of new cases of head and neck cancer in the United States was 40,490 in 2006, accounting for about 3% of adult malignancies. A total of 11,170 people died of their disease in 2006. The worldwide incidence exceeds half a million cases annually. In North America and Europe, the tumors usually arise from the oral cavity, oropharynx, or lary...
