Is this something to worry doctor ? I have read long exposure to bile reflux cause cancers . Last year I had too much heartburn and acidity especially during night while sleeping. So did a endoscopy . Which is attached for reference . And the doctor gave esogen d and rantac 150.. now my symptoms are almost gone . Rarely experience heartburn and acidity . So do I need to worry or go for surgery ? . It says lot of bile noted in stomach. I read lot of bile exposure can cause stomach cancer
