Hi, Thanks for writing in. Anxiety after hearing about serious diseases is usual, but you must not think that you have got the disease and will die from it. Most diseases have an underlying cause and a disease like lung or throat cancer will usually occur in people abusing tobacco by smoking or chewing. If you stay away from smoking and chewing tobacco then your chance of cancer in lung or throat is reduced by more than 90 percent. The symptoms of lung cancer are the following cough that does not go away or gets worse. Chest pain that is often worse with deep breathing, coughing, or laughing. Hoarseness. Weight loss and loss of appetite. Coughing up blood or rust-colored sputum (spit or phlegm)Shortness of breath. Feeling tired or weak. The symptoms of throat cancer are the followingAbnormal (high-pitched) breathing sounds. Cough. Coughing up blood. Difficulty swallowing. Hoarseness that does not get better in 1 to 2 weeks. Neck or ear pain. Sore throat that does not get better in 1 to 2 weeks, even with antibiotics. Swelling or lumps in the neck. Having a cancer in lung or throat in you is unusual. Please do not worry.
