Aspectos epidemiológicos da mortalidade por câncer de boca: conhecendo os riscos para possibilitar a detecção precoce das alterações na comunicação

“…However, studies have pointed towards growth on the prevalence of such tumors on females, particularly because of changes on the female behavior in the last decades 18 . The death ratio by gender for this study was 3:1, similar to other studies that depict higher proportion of death by mouth cancer among males 7,[17][18][19]22,[25][26][27][28][29] . Analyzing data related to death rates according to age group, there was no statistically significant difference between the age intervals (p = 0,2), as found in another similar study 26 .…”

“…The death ratio by gender for this study was 3:1, similar to other studies that depict higher proportion of death by mouth cancer among males 7,[17][18][19]22,[25][26][27][28][29] . Analyzing data related to death rates according to age group, there was no statistically significant difference between the age intervals (p = 0,2), as found in another similar study 26 . All deaths happened on individuals older than 40 years, with a prevalence ratio of 2,78 (p < 0,001) times higher among individuals who are 60 years or older, a finding also seen in other studies that highlight the occurrence of cases on individuals older than 50 years 18,22,[26][27][28] .…”

“…With the aging of the population, it is expected a considerable increase on cancer cases among the elderly population [29][30][31] . Most cases consisted of black or pardo individuals (62,07%), disagreeing with other studies that had identified higher representation of morbidity among white individuals 17,22,26,28 . Nonetheless, scientific evidence also points that black or pardo people, when compared to white people, tend to live farther from health services, usually due to unfavorable socioeconomic conditions, making it more difficult to have early diagnosis and specific treatment, leading to an unpleasant end for the disease 1,32 .…”

There are molecular reasons, related to the mechanisms of carcinogenesis and proliferation of the tumor cell, associated to the decline of the immune system that favor the higher risk of cancer in individuals older than 60 years.…”

“…Because it is a urban, touristic and residential area, the local population is usually involved in activities related to sales, education and tourism, a difference considering other studies that found a link between mouth and pharynx cancer and other fields of work, like fishing, agriculture, painting, butchery, construction, driving, plumbing, carpet installing, and other activities that demand physical work 7,22,26 .…”
