Is lung cancer contagious?

Can a person diagnosed with lung cancer transmit it to others when they cough or when they eat with family and friends?
The answer is no.
Unlike tuberculosis, hepatitis or other infectious diseases, lung cancer is not contagious. Therefore, loved ones and friends should give lung cancer patients more love rather than isolation, and give them support in life and spirit, which is a strong guarantee that lung cancer patients can survive for a long time.
