Abstract(s)
A cavidade oral é a área onde se encontram os cancros mais comuns das vias aerodigestivas superiores.
Os fatores de risco mais associados são o tabagismo e o consumo de álcool, embora haja outros fatores envolvidos.
Os cancros da cavidade oral podem desenvolver-se a partir de lesões pré-existentes conhecidas como pré-cancerosas ou potencialmente malígnas.
Estas lesões incluem leucoplasia, eritroplasia, líquen erosivo entre outras.
Os carcinomas continuam a ser os tumores responsáveis pela maior parte da patologia maligna da cavidade oral e, na maioria dos casos, surgem como lesões que mais tarde podem malignizar.
O diagnóstico é difícil e deve ser feito precocemente, a fim de garantir um tratamento o mais eficaz possível.
Apesar do grande número de casos a nível mundial, este tipo de patologia mantém-se ainda pouco conhecida do público em geral e os diagnósticos são feitos, de forma geral, tardiamente.
The oral cavity is the area where the most common cancers of the upper aerodigestive tract are found. The most associated risk factors are smoking and alcohol consumption, although there are other factors involved. Cancers of the oral cavity can develop from pre-existing lesions known as precancerous or pre-malignant. These lesions include leukoplakia, erythroplakia, lichen planus among others. Carcinomas remain the tumours responsible for most cancers of the oral cavity and in most cases, they arise as lesions that may later malign. Diagnosis is difficult and should be made early, to ensure the most effective treatment possible. Despite the large number of cases worldwide, this type of pathology is still little known to the public and diagnoses are generally made late.
