Lung cancer is when there is uncontrolled growth of abnormal cells in the lung. The diagnosis is if you have swollen lymph nodes, trouble breathing, abnormal sounds in lungs, dullness when your chest is tapped, then your doctor may suspect lung caner. The most common way that people get lung cancer is smoking. The cancer begins with a mutation in a cells DNA ; this is caused by cigarette smoke. Most tumors start with the irritation of the breathing tubes. This causes a build up of cells which gradually build up and turn into uncontrollable growth.
Lung tumors with Rhabdoid features have been included as variants of lung cancer. This is unusual and there are only 38 cases reported.
From 1975 to 1990 the lung cancer cases have gone up 41% in males and 31% females. Of the 8.1 million cases half the occurred in developing countries. There have been 5.18 million deaths. The number of cases has been increasing exponentially over the years. The causes of lung cancer are 90% in men and 80% in women caused by smoking cigarettes.
The treatments are radiation treatment; take medication, RF ablation, chemotherapy, or lung cancer surgery. Over the course of 15 years the cases of lung cancer have almost doubled. They hold clinical trials so they can test the new medications on willing lung cancer patients.
There has been a strong movement in the past 20 years to have kids in America become not exposed to cigarettes. No cigarette commercials can be shown on TV; they cannot be displayed on billboards. You can’t smoke until you are 18, and in health class teens are taught about the dangers of smoking.
We still do not fully understand the pathogenesis of lung cancer. So far we know that respiratory epithelial cells require many genetic alterations to become invasive and metastatic cancer. Environmental carcinogens and a gene locus determining susceptibility have been identified as causes of lung cancer.
When a mutated cell divides it passes along its abnormal traits to its daughter cells. Then the cells continue to divide and replicate mutated cells. This is how the growth of mutated cells happens uncontrollably.
Lung cancer has DNA sequence, it mutates the DNA .
Baylor University has created a vaccine that suppresses lung cancer in some patients.
Developing countries contribute the most to lung cancer deaths. Of the 5.18 million deaths from lung cancer 55% occurred in developing countries.
