I have been exposed to clinical tumors for 9 years, but I still have to treat them dialectically. If we can purposefully cooperate with western medicine treatment and Chinese medicine health care to carry out the whole course of disease, we will get the best effect. I'm not a Chinese doctor. Chinese medicine is too advanced to comment. I just answer you from your question: it's only four or five days before the operation. I suggest you take more rest and work regularly. After all, you need to rest for a while after surgery, especially after rectal cancer surgery. I haven't heard the saying that computers hurt qi and blood. Pay more attention to the diet after anus-preserving operation: limit excessive liquid intake to avoid too thin stool and inconvenient nursing; Correct constipation by supplementing fresh vegetables and increasing cellulose. Eat a variety of foods and avoid eating cold, spicy and greasy products.

Say a little more, since the anus-preserving operation shows that the situation is still optimistic, we should pay attention to regular review!

Give the best.
