The American Society of Oncologists has come to the conclusion that lung cancer can be recognized by indirect signs, for example, by laughing, reports the Daily Express.
According to doctors, one of the common symptoms of this disease is chest pain, aggravated by laughing, deep breathing and coughing. It can indicate a blockage in the lungs, fluid accumulation, swollen lymph nodes and swelling, experts say.
Lung cancer can be revealed in other ways, paying attention to a long-lasting cough with blood discharge, hoarseness, loss of appetite, weight loss, fatigue, weakness, and frequent relapses of bronchitis or pneumonia. And with a Pancost tumor growing in the upper part of the lung, drooping or weakness of one eyelid, a decrease in the pupil in one of the eyes and the cessation of sweating on one side of the face are possible.
When other organs are damaged, a person may suffer from bone pain, joint swelling, headache, numbness of the limbs. Balance problems, cramps, yellowing of the skin and eyes, and swollen lymph nodes are also possible.
