Some 22,000 people die each year from these tumors in Central and South America. 72% of the cases are men.
Some 22,000 people die and more than 45,000 are diagnosed each year in Central and South America, where the highest incidence rates are reported by Brazil and Uruguay. and Argentina, in addition to Cuba, said the experts of this disease.
"The region reports 7% of deaths in the world of head and neck cancer and also has one of the highest incidence rates (new cases," says Colombian Sandra Perdomo , part of a Latin American research project of the International Agency for Research on Cancer (IARC) on this carcinoma.
Perdomo quotes an IARC analysis that collected information on 48 records in 18 countries from Central and South America and in which it has been detected that among those who have the highest number of head and neck cancers, we find Brazil, Uruguay and Argentina , as well as Cuba, In the registered countries, Brazil has the highest incidence rates (19.7 per 100,000 population for men and 5 for women), followed by Uruguay (16). , 9 and 10,1)., Cuba (10 and 3,6), Argentina (6,4 and 2,2), Colombia (5,2 and 3), Chile (3,4 and 1,6) and Peru (3 and 2.8). 9659005] The lowest number of new cases is reported by El Salvador and Mexico, below 2.7 per 100,00 inhabitants; Bolivia and Ecuador, with rates below 2.
Cancer of the head and neck can compromise the nasal cavity and throat, but is more common in the mouth, larynx and pharynx.
According to the Latin American project of IARC, called "InterCHANGE" and which includes research centers in Colombia, Argentina, Uruguay and Brazil, consumption of alcohol and tobacco is the main risk factor associated with this carcinoma.
For Perdomo, molecular epidemiologist and expert in the biology and cancer clinic, precisely the high incidence of this disease in several countries of the region is associated with high consumption of tobacco and alcohol.
International organizations, including the World Health Organization (WHO), have warned that the human papillomavirus (HPV) can also infect the mouth and throat and contribute to the development of cancer in these sites.
"Unprotected oral sex with a person who has contracted HPV exposes him to develop this cancer. Patients with HPV develop a type of head and neck cancer that generates fast growing tumors, so it's important to have access to fast treatment, "says Clara Arango, oncology consultant.
At least 500,000 new cases and 375,000 deaths from head and neck cancer worldwide
IARC estimates that if the trend persists, the global burden of head and neck cancer will increase by 34% by 2030. register one million new cases and 576,000 annual deaths, while in Central and South America, it will increase by 7% (72,985 new cases and 37,909 deaths) .
This Friday, July 27, World Head Cancer Day was commemorated and the neck, which seeks to attract attention to recognize the symptoms and improve care for those who suffer.
"Diagnosis is precisely one of the research challenges because, although some symptoms are very obvious, for example in oral cancer, the diagnosis is delayed in most cases", explains Perdomo
Depending on the characteristics of the tumor, treatments include chemotherapy, surgery, radiotherapy or targeted therapy, adds Arango, also medical officer at Latam Merck.
