The appearance of lung cancer can sometimes be seen with laughter. Daily Express writes about it.
The American Cancer Society believes that in the early stages of lung cancer is usually asymptomatic, so it is important to detect the first signs.
A common symptom of the disease, doctors believe, is chest pain during laughter. It may indicate congestion in the lungs, fluid accumulation, increased lymph nodes and tumors and become stronger when breathing deeply and coughing.
