Thanks for your question on Healthcare Magic.
I can understand your concern.
No need to worry for cancer or any major disease because you are too young for cancer.
In my opinion, your symptoms are mostly due to GERD (
gastroesophageal reflux disease).
GERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause
chest pain,
hyperacidity etc.
Smoking and tobacco are biggest risk factors for GERD.
So first of all quit smoking and
tobacco chewing.
Avoid hot and spicy food. Avoid stress and tension, be relax and calm. Avoid large meals, instead take frequent small meals.
Take antacid like
pantoprazole on empty stomach.
Go for walking after meals.
Don't worry, you will be alright. Don't think too much about cancer.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
