Heartburn and acid regurigation. "c".

I am suffering from heartburn from last 2 years and have more than thrice in week. i also consulted a doctor he advised me to go through Endoscopy and Sonography. So, after analysing he told me that i am sufferinf from gall bladder cholestrolsis and hyper acidity pand the count of H. pylori bacteria is high. Recently i had gone through a blood test to check my Vitamin B12 . and the results is 20 count of vitaminB12. After that i had taken 10 injection of vitamin b12. Now again i am suffering from severe heartburn and acid regurigation i dont have any kind of chest pain or any other symptoms i simply get too hot burp which results pain in throat and weird sensation in chest and throat. Kindly help me out i am too worried because i read an article where its written too much of heartburn causes food pipe cancer. and i am 24 Male scared of the letter "C" . Thank you i will be highly obliged if you will sort out the problem
