Lung cancer is a type of cancer that begins in the lungs, characterized by the uncontrolled growth of abnormal cells. These cells can form tumors that interfere with normal lung function and may spread to other parts of the body (metastasis).
Lung cancer is classified into two main types:

Lobectomy – Removal of one lobe of the lung.
Pneumonectomy – Complete removal of a lung in advanced cases.
Segmentectomy – Partial lung removal for early-stage cancer.
High-energy rays target and destroy cancer cells. Used alone or post-surgery.
Systemic drug therapy to kill cancer cells or shrink tumors before surgery.
Boosts the immune system to recognize and attack cancer cells.
Precision medicine aimed at genetic mutations fueling tumor growth.
Want to find out more about the treatment? The answer to your questions can be found below.
Can lung cancer be detected early?
Yes, early detection through low-dose computed tomography (LDCT) screening significantly improves survival rates, especially in high-risk individuals such as long-term smokers. Regular screenings help detect cancer before symptoms appear.
Can lung cancer be cured?
Yes, lung cancer is curable if detected early. Localized tumors treated with surgery, radiation, or a combination of therapies have high survival rates. Advanced-stage lung cancer can be managed with targeted treatments and immunotherapy.
How does lung cancer spread?
Lung cancer spreads through the lymphatic system or bloodstream, affecting lymph nodes, bones, liver, brain, and adrenal glands. Early intervention slows or prevents metastasis.
How does targeted therapy work for lung cancer?
Targeted therapies attack specific genetic mutations (e.g., EGFR, ALK, KRAS) in cancer cells, blocking signals that promote tumor growth. These treatments are highly effective with fewer side effects than chemotherapy.
Is lung cancer only caused by smoking?
No, while smoking is the leading cause, non-smokers can also develop lung cancer due to exposure to secondhand smoke, air pollution, radon gas, asbestos, and genetic factors.
What are the survival rates for lung cancer?
Survival rates depend on the stage and type of lung cancer. Early-stage NSCLC has a 5-year survival rate of 60-70%, while advanced-stage cases have lower survival rates. Targeted therapies and immunotherapy have improved long-term outcomes.
Can lung cancer cause symptoms in areas beyond the lungs?
Yes, metastatic lung cancer can cause bone pain, neurological issues (if spread to the brain), jaundice (if spread to the liver), or hormonal imbalances (paraneoplastic syndromes).
