Effects of Smoking on Lung Cells
When a person smokes, they inhale a variety of harmful chemicals into their lungs. These chemicals can cause damage to the cells lining the lungs over time. The damaged cells may start to grow abnormally, increasing the risk of cancer development.
Formation of Cancerous Tumors
The damaged lung cells that have been exposed to the toxins in cigarette smoke may turn cancerous. These cancerous cells can multiply uncontrollably, forming tumors in the lungs. The tumors can interfere with the normal function of the lungs and lead to severe health complications.
Role of Smoking in Lung Cancer Development
Smoking is the leading cause of lung cancer worldwide. The carcinogens in tobacco smoke directly affect the DNA of lung cells, causing mutations. These mutations can trigger the uncontrolled growth of cells, leading to the formation of malignant tumors.
Health Implications of Smoking-Induced Lung Cancer
Lung cancer is one of the most deadly forms of cancer, often diagnosed at an advanced stage. The prognosis for lung cancer patients is generally poor, with low survival rates. Quitting smoking can significantly reduce the risk of developing lung cancer and improve overall health outcomes.
