Not exactly. Terminal lung cancer is lung cancer that can lead to death. However, when lung cancer is diagnosed early and treated in a timely manner, the advancing disease can be slowed down and the patient can live a longer life. A (2019) research paper published in BMJ suggests that lung cancer in India has a one-year survival of ‘87.3% for stage 1 and 18.7% for stage 4. The 5-year survival rate for lung cancer is 10%’. The five-year survival rate is just a mathematical way of estimating life expectancy in a selected population.
Lung cancer starts when the toxic foreign particles in the lungs damage the normal lung cells making them cancerous. The altered cells behave abnormally, multiply uncontrollably and fail to perform regular metabolic functions. According to Centers for Disease Control and Prevention, advances in medical science have allowed scientists to develop treatments like surgery, chemotherapy, radiation therapy, and targeted therapy to kill the primary growth as well as cancer cells that have spread to different organs and to inhibit the formation of new cancer cells.
However, all these treatments can only treat lung cancer but cannot always cure the condition completely.
