UNDERSTANDING LUNG CANCER

What to know

This page provides a starting point for learning about lung cancer. Cancer types and individual experiences vary, and information here is not a substitute for personalized medical guidance.

Possible signs

Persistent cough, coughing blood, chest pain, shortness of breath, or unexplained weight loss may need medical evaluation. Screening with low-dose CT is recommended only for certain people at high risk.

  • Keep track of changes that are new, persistent, or unusual for you.
  • Symptoms can have many causes and do not necessarily mean cancer.

Risk factors

Smoking is the leading risk factor, but people who have never smoked can also develop lung cancer. Radon, secondhand smoke, air pollution, and workplace exposures can contribute.

  • Having a risk factor does not mean a person will develop cancer.
  • Share relevant personal and family history with a healthcare professional.

When to seek guidance

Discuss new or persistent symptoms with a healthcare professional. Ask whether you meet current criteria for low-dose CT screening; screening is not recommended for everyone.

  • Ask about tests, screening, or follow-up appropriate to your age and personal risk.
  • Seek urgent care for severe or rapidly worsening symptoms.
Important: Educational information only. This page cannot diagnose symptoms or recommend an individual treatment plan. Consult a qualified healthcare professional about health concerns.
