Question 1

What is lung cancer and how does it develop?

Accepted Answer

Lung cancer develops when lung cells acquire mutations that disrupt normal regulation of growth and death. These mutated cells proliferate abnormally, forming tumors that may invade nearby tissue or metastasize via lymphatic or blood circulation.

Question 2

What are the early symptoms of lung cancer?

Accepted Answer

Early symptoms often include a cough that doesn’t improve, chest pain that worsens with deep breathing or coughing, hoarseness, weight loss, fatigue, shortness of breath, and frequent respiratory infections.

Question 3

How is lung cancer diagnosed?

Accepted Answer

Doctors may use chest X-rays, CT scans, PET scans, biopsies, and sometimes blood tests to detect lung cancer. Imaging helps identify abnormalities, while biopsy confirms the diagnosis.

Question 4

Can lung cancer be cured or treated successfully?

Accepted Answer

Yes—especially if detected early. Treatment options include surgery, radiation, chemotherapy, targeted therapies, and immunotherapy, tailored to cancer type and stage.

Question 5

Is lung cancer always caused by smoking?

Accepted Answer

No, while smoking is the leading risk factor, lung cancer can also occur in non-smokers due to genetic factors, exposure to radon, air pollution, or secondhand smoke.

Question 6

How does lung cancer spread in the body?

Accepted Answer

Lung cancer can spread (metastasize) through the lymphatic system or bloodstream to other organs like the brain, bones, liver, or adrenal glands.

Question 7

What are the most common types of lung cancer?

Accepted Answer

The primary categories are non-small cell lung cancer (NSCLC)—which includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma—and small cell lung cancer (SCLC), which is less common but more aggressive.

Question 8

Can lung cancer be hereditary or genetic?

Accepted Answer

Yes. Inherited mutations and family history can increase lung cancer risk, even in non-smokers. Specific gene alterations, such as EGFR or ALK, may also drive certain cases.

Question 9

Is lung cancer screening covered by insurance?

Accepted Answer

Yes. Low-dose CT (LDCT) screening is generally covered for high-risk individuals (age 50–80, >=20 pack-years smoking history, current smokers or quit within last 15 years) under Medicare and most private insurance with no cost-sharing.

Question 10

What are the most common sites where lung cancer spreads?

Accepted Answer

Common metastatic sites include the brain, bones, liver, and adrenal glands. Spread to these areas can lead to specific symptoms depending on the organs involved.
