You can drink tea after 6 months of chemotherapy after colon cancer surgery, but pay attention to moderation and avoid drinking strong tea. After surgery and chemotherapy, colon cancer patients can usually get the disease under control, and some patients can even be cured. Tea does not contain substances that cause cancer or recurrence of cancer, so patients can drink tea appropriately after treatment. When drinking tea, patients should pay attention to the right amount and do not drink strong tea, because strong tea may lead to central nervous system excitement and affect patients’ rest. After treatment, patients should pay attention to light diet and try to avoid stimulating and spicy food. Meanwhile, ensure the supply of nutrition and adopt the method of eating less and more meals. After treatment, colon cancer patients should follow the doctor’s prescription for regular review to avoid recurrence of the disease.
