The term <\/span>Head and neck cancer <\/b>refers to tumors that develop in sites such as the mouth, pharynx, larynx, nasal cavity, paranasal sinuses, thyroid, and salivary glands. Together they represent approximately 3.6% of all reported cancers and about 2% of deaths attributed to cancer. Of all of them, in our country, the <\/span>most common are the oral cavity (44%), larynx (31%), pharynx (25%)<\/b>.<\/span><\/p>\n

It is considered to <\/span>tobacco use <\/b>A s the main risk factor associated with the appearance of these tumors, people who have a higher risk of developing this disease have used tobacco for more than 35 years. The risk increases when tobacco consumption is combined with alcohol consumption, thus close to the <\/span>75% of head and neck tumors are related to these two factors<\/b>.<\/span><\/p>\n

Most<\/span> cases <\/b>of head and neck cancer occur in <\/span>mens <\/b>with <\/span>an <\/span>average<\/b> age of 60 years<\/b>, although the age of appearance has been reduced mainly in <\/span>oropharyngeal<\/b> cancer <\/b>(area that covers the part of the throat, “angina” and base of the tongue). In recent years, this type of cancer has increased in young non-smokers, due to a higher incidence of throat infection due to <\/span>human <\/b>papillomavirus<\/b> (HPV). As serious as it may seem, it is these latter cases that are associated with a better prognosis compared to cases related to tobacco use.<\/span><\/p>\n

HPV is a virus of which more than 150 types have been identified. Most of them infect the skin and are responsible for the formation of warts, some types are sexually transmitted, that is, they are transmitted through contact with the genitals. In most cases, the immune system can fight infections caused by these viruses, but in some people the infection can remain for a long time without symptoms and develop cancer at the infected site. HPV has been classified into two large groups: low risk and high risk (HPV 16 and HPV 18); this depends on the probability of generating premalignant lesions such as red ulcers (erythroplakia) or whitish plaques (leukoplakia) or even cancer.<\/span><\/p>\n

The cancers most related to HPV infection are: <\/span>cervical cancer, anal canal cancer, oral cavity cancer, and doropharynx cancer<\/b>.<\/span><\/p>\n

Generally, the <\/span>Symptoms and signs <\/b>presented in head and neck cancer are related to an ulcer or “lump” that presents a gradual growth (the discomfort presented depends on the affected structures), changes in the voice (hoarseness), or chronic cough. For the above, <\/span>many times these types of conditions take time to be detected as they are confused with upper respiratory tract infections, foreign bodies or allergic processes<\/b>.<\/span><\/p>\n
