Testing for lung cancer warning in smokers

US scientists have discovered a way to inform high smokers about lung cancer risk by measuring changes in the windpipe.

This test hopes to help detect this deadly cancer soon, making treatment easier.

And if the test results, the next question will be: can the situation be reversed before the actual malignant cells appear? Researchers have found that there is an improvement in the number of people who are given the experimental drug.

Dr. Avrum Spira, Boston Medical University (USA), leader of the study said: 'It is estimated that 10-20% of smokers have lung cancer. The risk depends on how many cigarettes they smoke, for how long and how long they have quit. However, it is impossible to predict who will or will not get lung cancer. There is currently no way to detect tumors at an early stage. Most cases of lung cancer are only detected when it's too late. "

Second-hand smoke with toxins will spread deep into the respiratory system and that is why Spira's team focused on finding early signs of lung cancer.

In addition to the direct signs that the substances are in the throat, Spira also noticed the signs of genes in the trachea in smokers, each smoking with lung cancer. Spira analyzed the cells of 129 people who were and ever smoked and found that the genes involved in cancer were PI3K. When PI3K is too active, excessive cell growth may occur.
