CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this quiz evaluate?
It reviews common respiratory symptoms, broader health changes, and exposure or lifestyle factors linked to lung cancer risk. It is intended as a self-check to help identify reasons to seek medical evaluation.
Can the results confirm lung cancer or provide a personal risk percentage?
No, the results cannot diagnose lung cancer or calculate an individual probability. Similar symptoms and exposures can occur for many other conditions, and only a clinician can assess the cause.
When should urgent medical care be sought?
Seek urgent care for coughing up blood, severe breathing difficulty, intense chest pain, fainting, confusion, or blue-gray lips or skin. These symptoms require immediate evaluation.
How long does the quiz take and how many questions are included?
Estimated completion time is about 10 minutes. The quiz includes 15 questions.
How should answers be selected if symptoms vary over time?
Select the option that best reflects the most recent pattern or the most concerning level. If a symptom is persistent or worsening, medical follow-up is recommended even if the quiz score seems low.

Seek urgent help for coughing up blood, severe breathing difficulty, intense chest pain, fainting, confusion, or blue-grey lips or skin.
