Hi, I Have Problems Swallowin, Chucking With Solid Food, A

Hi, I have problems swallowin, chucking with solid food, a lot of pain in my lower esophagus after eat. I'm only able to tolerate a bit of liquids, feel pressure in my chest sometimes with pain. My GI diagnosed me with GERD and scar tissue but she said can't explain why I'm getting so bad. Had 9 dilatations in the past 4 months. My primary doctor referred me to a gastro surgeon. I'm worry because my family is a high percentage of cancer of esophagus and stomach.
