#5:. Indigestion or trouble swallowing.
A prolonged painful burning sensation in your throat or chest shouldn’t be ignored – even if you suspect it’s from eating spicy food.
Don’t think that regular indigestion or trouble swallowing is a normal part of aging either. It can be a sign of esophageal, stomach or throat cancer.
#6:. Persistent cough or hoarseness
Do you have a nagging cough? If it lasts more than three weeks, it’s a sign that something’s wrong. And whether you smoke or not, a cough that doesn’t go away can be a sign of lung cancer.
Persistent hoarseness, wheezing, shortness of breath or coughing up blood are also signs to call your doctor right away.
