Should a gastric submucosal tumor be biopsied?

Ask
Hello doctor. I had a gastroscopy and found a tumor under the gastric antrum measuring 0.6 cm. The gastroenterologist just told me to monitor and check once a year. I'm so worried, I don't know what's wrong? Should the tumor under the gastric antrum should be biopsied to know whether it is benign or malignant? Because I'm afraid, I only go to the doctor every 1 year in case the tumor gets bigger and the disease progresses. Thank you doctor.

Hello. Gastric submucosal tumors are usually mesenchymal and gastric myoma. In case, you have a tumor under the gastric antrum, you can combine endoscopic ultrasound to get accurate results, then biopsy the tumor to make histopathology.
You should do it at reputable medical facilities or hospitals under Vinmec Health System for advice by qualified doctors. We look forward to seeing you at Vinmec as soon as possible.
