Stomachache, sore throat, cancer?

Stomach pain and sore throat are not necessarily cancer. There are many causes of stomach pain and sore throat, such as reflux esophagitis, gastritis, gastric ulcer, excessive heat, pharyngitis, etc. If there are symptoms of indigestion or excessive drinking, it will also cause stomach pain; stomach acid and stomach contents stimulate the throat after vomiting, which will cause sore throat. However, if there are symptoms such as loss of appetite, weight loss, hematemesis, hematochezia, etc., and there is a lump in the upper abdomen, it is considered to be caused by cancer. Systematic examinations, such as imaging and pathological biopsy, should be carried out in time to confirm the diagnosis.
