[Aetiopathology and prevention of oropharyngeal cancer].

Oropharyngeal cancer is in the sixth position of cancer incidence in the world (after colorectal, breast, prostate, bladder, and cervix uteri cancer). More than 90% of them are squamous cell carcinoma. This type of cancer can originate on the lip, oral cavity, pharynx, and larynx. The risk factors associated with oropharyngeal cancer are tobacco, alcohol, and poor oral hygiene. However, other conditions, such as infection with human papilloma virus (HPV) and oral dysbiosis, are gaining prominence. Pre-malignant and malignant lesions are related to diverse factors that can be monitored by the health professional. These professionals are also in an ideal position to influence and advise patients on healthy life habits that contribute to prevent or treat metabolic-endocrine syndromes associated with the development of pre-cancerous disease and cancer located in different organs.
