[|AI|]  Hello, Thank you for contacting ChatDoctorI understand your concern, I am Chat Doctor, Infectious Disease Specialist answering your query. ESR is erythrocyte sedimentation rate, and LDH is lactate deny Chat Doctor. ESR is the marker of the nonspecific inflammation, as you have CA stomach it may be raised because of the inflammation associated with it. Some tumors produce LDH, it is a one type of enzyme which arises from the cancer producing cells. So once you get treatment for the cancer, this marker will start disappearing.X-ray are normal but cancer producing cells are much smaller and can't be detected in the x-ray. That is why your X-ray is appearing normal. You can ask for further queries here on bit.ly/
