The lungs are paired-cone shape organs. They are the primary organ of respiratory system. Their function is to release carbon dioxide during exhalation and take in oxygen during inhalation. Cancer is defined as the abnormal growth of cells. Cancer that forms in the lungs is known as lung cancer. Due to rapid abnormal growth of cancer cells in the lungs the healthy tissues of the lungs can be damaged. Unlike normal cells, cancer cells grow without any control. Therefore, lung cancer can be very difficult to treat as it spread quickly. Lung cancer spread through bloodstream to the brain, liver, adrenal glands, bones and other organs.
According to WHO in 2020, lung cancer was the second most common cancer statistically 2.26 million cases worldwide with 1.80 million deaths. Studies indicate that the mortality rate of lung cancer is very high and the survival rate is 10-15%
In United States, people die from lung cancer more than any other cancer.
