About a week ago I started having problems with swallowing... It hurts a bit while I swallow, sometimes I feel as if I have something in my esophagus... It's like slightly choking me in my throat and near my stomach. I went to a doctor and he said that it's just a cold... But I'm a hypohondriac, so I'm very nervous and my condition is not improving... I feel just a bit better, but still have problems with swallowing... I feel scared and nervous all the time, sometimes for no reason and that's worsening my condition... My grandfather died early this year from esophagus cancer and I'm afraid that I may have it too. Is it possible? I don't smoke, I'm not an alcoholic and I'm 21 years old... Do I have cancer?
