Because there are many types of cancer, the symptoms of cancer recurrence may be localized or in the same location, as well as the appearance of new lumps or enlarged lymph nodes around, or metastasis from other parts of the cancer, and other manifestations. However, the recurrence symptoms exhibited by different parts of cancer are different, the common ones are as follows: 1. Stomach cancer: recurrence symptoms may lead to inability to eat, acid reflux, heartburn, abdominal pain, etc.; 2. Pancreatic cancer: it usually triggers severe pain around the navel and upper abdomen. Imaging examination may reveal a re-growing mass in the original pancreatic surgery area, or liver or lung metastasis, thus triggering the appearance of corresponding symptoms; 3. Esophageal cancer: recurrence of anastomosis or lesions above and below the original esophageal tumor or in the stomach, suggesting disease progression and further anti-tumor treatment.
