An unbalanced diet, a stable lifestyle, smoking, weight gain and alcohol use have shown several cases of cancer, according to a study.
Smoking, alcohol consumption, overweight, unhealthy eating and physical inactivity are associated with one-third of deaths from 20 speciescancerIn Brazil, according to a new study. Published in the scientific journalCancer epidemiology, The work indicates that out of the total annual incidence of tumors, at least 114,000 (27% of the total) will be avoided with a healthy lifestyle. The lives of 63,000 people (34% of the total) can be saved.
The data comes from an investigation by researchers from the Faculty of Medicine of the University of Sao Paulo (FM-USP) and Harvard University in the United States, with the support of the Research Support Foundation of the State of Sao Paulo (FAPESP).
According to the survey, lung, throat, pharynx, esophageal cancer and colorectal cancer will be reduced by half if these five risk factors are eliminated completely. "According to many previous studies, there is no other procedure that can prevent many cases," said Leandro Resende, researcher at FM-USP and one of the authors of the article. In an interview with Agência Fapesp: "Primary prevention through lifestyle modifications is one of the most realistic and realistic ways to combat diseases in Brazil."
Cancer is among the leading causes of death in Brazil. According to World Health Organization (WHO) data, 2025 cases are expected to increase by up to 50% in the country, mainly due to population growth and population aging.
There is consensus in scientific literature that smoking, sedentary lifestyle, alcohol consumption and excessive and unbalanced diet are linked to the development of 20 types of tumors. Among other things, the new study calculated the population fracture (FAP) – a measure capable of estimating the proportion of cases to be avoided if these five risk factors are eliminated from the total population – in these cancers.
On this basis, the researchers reached the data we mentioned earlier. In addition, they identified how each of these habits, in isolation, affected the number of cancers in Brazil, until they were separated by sex.
According to the analysis, smoking was responsible for 67,000 cases and 40,000 deaths per year in Brazil. This innovative arrangement was followed by weight gain (21,000 episodes of illness and 13,000 deaths) and alcohol consumption (16,000 cases and 9,000 deaths).
"We have made a lot of progress in the last ten years, with many laws and measures that have reduced the prevalence of smoking by more than half." However, it remains the main cause of cancer, "Rezende said. "This reinforces the need for marketing campaigns, fees and restrictions."
In gender analysis, men and women were affected differently. In the men's suite, cigarette smoking had a greater impact on the spread of cancer than inadequate diet, weight gain, physical inactivity, and alcohol consumption. In women, the opposite happened: the sum of these last four factors was more predominant than smoking.
"There is a difference because smoking is still higher among men in Brazil, but that's not all: women are more affected by other factors, they are less physically active and have a higher body mass index."
