Lung Cancer
Genes linked to lung cancer
Three genes are implicated in the genesis of lung cancer, apparently found on human chromosome 14, and two of them are involved in fetal development of the lungs. This was affirmed by researchers at Cold Spring Harbor Laboratory in New York County (United States).
In this study the three genes involved (TTF1, NKX2-8 and PAX9) would be activated and would cause a pattern of fetal gene expression, causing abnormal proliferation of cells that give rise to the tumor.
Apparently, the mutations of these genes is common in some types of lung cancer. The mechanism by which these genes are activated in the fetal stage of growth in the adult is not known exactly, but if you know that if you disable these genes could halt tumor growth.
The most important thing is that the tumor may regress if these genes are turned off. Although this is still under study and will take years before it can be applied directly as a treatment for advanced lung cancer.
Lung Cancer Increased in 2020
Are two curves diverge: while lung cancer mortality in Spain and most other EU countries lower among men (the exception is Portugal), among women not only rises, but is accelerating. Specifically, between 1990 and 2007, a spokesman for the Spanish Health Ministry said that the lung cancer mortality in men decreased by 19% in the EU, and 4% in Spain. In contrast, among women increased by 39% in the EU, a rate that Spain doubles and reaches 73%. 20% of women smoke, a figure that increases slightly in each National Health Survey.
Compared with what is, by far, the first female cancer, both incidence and mortality, “the breast, is that in the EU, the mortality has fallen by 9% between 1990 and 2007, and Spain 24%. The projection of what will happen in Spain seems clear. With the delay due to the late entry of women to smoking, the country follows the same path traveled by U.S. and northern Europe, where lung cancer is already the leading cause of death in women, ahead of breast (in large studies comparing these two women with colorectal cancer, which are the first, and in men breast changes the prostate). For example, this is the case in Denmark since 1996. In Hungary the case since 2005 or so. And if it confirms the trend, and there is no indication that it will not be confirmed, the projections are that Spain will occur after 2020, indicates Massutà Bartholomew, secretary of the Spanish Group for Lung Cancer (GEPC).

Lung cancer for non-smokers, the guilt of a gene
A gene is responsible for lung cancer in non-smokers
Research sheds light on the possible genetic origin of lung tumors in their lives in those who have never smoked a cigarette or almost
lung-geneMILANO – Sick of lung cancer and had never touched a cigarette is possible. But there is a genetic explanation. The ‘fault’ is a gene, the ‘GPC5. Scientists believe that a low activity of this gene is responsible for the disease. Read the rest of this entry »
Discovered the head of lung cancer in nonsmokers
The lungs are one of the areas most affected by cancer and we know how to be a smoker goes to affect the possibility of getting sick.
But unfortunately, even for those who have never lit a cigarette, there is also a risk of developing lung cancer. Sure, of 15-20 times lower than those who smoke but, nevertheless, among the sick is a tangible 53% women and 15% of male non-smokers. Read the rest of this entry »
Lung cancer may have genetic causes
Smoking is the most frequent cause of lung cancers, but there is a significant number of people developing the disease too, having never smoked. Even if another risk factor for non-smokers is passive smoking, there is another cause that can cause cancer, without there ever having been exposed to tobacco smoke.
A percentage of 30% of patients with lung cancer, it would be for a genetic cause. To find U.S. researchers who have found genetic variations responsible for these cases of lung cancer. Read the rest of this entry »
Non-smokers risk lung cancer due to gene
The cause of lung cancer in nonsmokers is attributed to GPC5, a gene that is activated or deactivated in two stretches of the genome. Researchers at the Mayo Clinic College of Medicine in New York have used a Capone of 574 people who had smoked a maximum of 100 cigarettes in their whole life.
So many people suffering from lung cancer despite never having touched a cigarette. And this is anger: how is it that we can get sick without somehow facilitated cancer? Read the rest of this entry »
Lung Cancer
Cells are the smallest living units of the human body. One function is to reproduce and die when no longer useful. This process is very neat, in time and space, so there is always that allows the appropriate number of cells for each stage of life.
When this multiplication of cells occurs in an uncontrolled manner, forming lumps. These masses are called tumors.
There may be benign and malignant tumors. Benign tumors are those that do not spread to other areas and do not compromise a person’s life. Read the rest of this entry »
