Chemotherapy for esophageal cancer does not have much effect, and radiotherapy can be done. Esophageal cancer, also known as esophageal cancer, is a kind of malignant tumor, which often manifests as choking sensation and foreign body sensation when swallowing food. Patients with esophageal cancer who have little effect of chemotherapy can have radiotherapy, which can effectively kill local cancer cells and reduce the size of local lumps. If patients with esophageal cancer undergo radiotherapy before operation, it can also effectively improve the rate of surgical resection; after operation, it can reduce the risk of tumor metastasis and recurrence. Esophageal cancer patients should keep a relaxed and happy mood in daily life, can increase sports appropriately to enhance immunity, but avoid overwork, and avoid stimulating food such as alcohol and chili peppers in their diet, they can eat high-quality protein food such as eggs, milk and meat appropriately, and eat more fresh vegetables and fruits. Patients with esophageal cancer should actively cooperate with doctors for treatment so as not to delay their condition.
