How is lung cancer detected?
Doctors detect lung cancer with tests like chest X-rays or CT scans that show any unusual spots in the lungs. If something looks doubtful, a small tissue sample (biopsy) is taken to confirm cancer. Early tests help find the disease sooner.
What are the symptoms of lung cancer?
A long-lasting cough, coughing blood, chest pain, and breathing difficulty are common signs. People may also feel weak, lose weight, or get frequent chest infections. Any symptom that stays for weeks should be checked by a doctor.
What causes lung cancer?
Most lung cancer happens due to smoking or breathing in polluted air and harmful chemicals for many years. Even non-smokers can get it because of family history or secondhand smoke. Sometimes the exact reason is not known.
How is lung cancer diagnosed?
Diagnosis starts with scans to look inside the lungs, followed by a biopsy to confirm the type of cancer. Doctors may also do blood tests or special scopes to understand how far it has spread. This helps choose the right treatment.
Can stage 4 lung cancer be cured?
Stage 4 lung cancer is very advanced, so curing it completely is difficult. But treatments like immunotherapy, targeted drugs, and chemotherapy can slow the disease and help patients live longer. Care focuses on comfort and improving life quality.
Why does lung cancer happen?
Lung cancer happens when lung cells get damaged and start growing wrongly. Smoking, pollution, and chemical exposure increase this damage. Age and genetics can also make some people more at risk.
