Lung Cancer

Lung cancer represents one type of lung cancer that typically originates from the cells lining the airways. It is one of the most deadly and common forms of cancer worldwide. NSCLC and small cell lung cancer (SCLC) are the two main types of lung cancer that are frequently detected.
Lung cancer that is not small cell:
Non-small cell lung cancer (NSCLC) is classified into three subtypes: adenocarcinoma, squamous cell carcinoma, and giant cell carcinoma.
Non-small cell lung cancer accounts for about 85% of lung cancer cases (NSCLC).
Spread and Growth: Generally speaking, it expands more slowly than SCLC.
Lung cancer with small cells, or SCLC:
The defining feature of small-cell lung cancer (SCLC) is the rapid proliferation of tiny cancer cells, which often lead to large tumors.
Aggression: SCLC is generally more aggressive and has a higher propensity to spread to other parts of the body.
Pulmonary cancer risk factors include:
Cigarette smoking: Smoking is the main cause of lung cancer. Smoking significantly increases the risk of lung cancer, though nonsmokers can also get
