The number of tobacco-related tumors is doubled over the last decades

Tobacco use tumors have grown significantly in the last decades in the field of Health in León. From 1997 to 2014, studies and 7,103 cases are included, among which women are noteworthy. Figures are similar to the rest of the Spanish population and can avoid this risk factor.

Between 1997 and 1999 the first quarter of the quarter, 116,000 cases were 100,000 men. In the last decade, this work, from 2012 to 2014, reached almost 228, almost doubling. Female figures are smaller, but the increase is noticeable. In the 1990s, there were 19.8 percent of the total of 100,000 women, and in the last three years it doubled at 44.5.

"75% of the tumors studied correspond to pulmonary and bladder cancer, but they are much more like lip, tongue, redness, oropharyngeal, nasopharynx, hypopharynx, nose and larynx," explains DiCYT Lidia García Martínez, University of Lleida Biomedicine Institute (IBIOMED), Group of Gene-Environment and Health Interactions Group.

The increase in the number of cases every year is remarkable, according to data published in the Medicine Family Association, in Primary Care Hospitals (SEMERGEN), more than 300 in 1997 and around 500 in 2014. "We believe that 59% can directly be affected by tobacco, with 170 deaths this year in the health field in Lleida," says experts.

Among the most striking data of the study, women have also increased women's growth from 1997 to 30, and since the 80's, in the 80's. "Especially since the prevalence of women smokers in the past decades has been growing and this time," warns Lidia García.

There are some geographical differences that determine smoking habits within the province. For this reason, the study implies the concept of "relative risks", that is, the more likely it is for a person to suffer from cancer (in this case, tobacco) in a particular municipality. In this case, according to the research, the suffering of tumors studied in Villadangos del Páramo and Don Juan in Valencia is three to four times the probability, respectively, than the average of the León Health Area.

"Geographical differences have been found to apply preventive strategies tailored to local situations, to reduce the prevalence of smokers and prevent the introduction of young people," he says.

In this sense, all data of this research may be useful in the face of prevention. In general, "the message we want to launch is very clear, every year more than seven million people die from tobacco worldwide, this is not a possible death," says IBIOMED researcher.

To this end, "we first want to know that we are avoiding the public health problem, the reduction of new smokers is reduced to increasing the price of tobacco and increasing accessibility and allowing smokers to stop".

The data collected by León are based on other Spanish-assisted authors, especially in the case of lung and bladder cancer, which develops in both sexes in recent years. However, there are some peculiarities in this area of ​​health. For example, rates of larynx canker against women are the highest in Spain, per 100,000 inhabitants per case. In the case of men, the rate of 14.6 is 100,000, similar to the rest of the communities.

"The heterogeneous distribution of tumors is not seen in our area, the prevalence of pulmonary and bladder cancer has no geographic inequality within the tumor associated with tobacco," the expert said.

The group of the same group has studied the main tumors registered in the leon: colon cancer, gastric, breast, prostate and bladder. From now on, in the next research work, many of them may extend their study time or continue researching other major tumors. (Source: José Pichel Andrés / DICYT)
