Cancer will die if you don't eat or drink for a few days.

If the patient is in a mild condition and has a good constitution, although

he does

not eat or drink, he actively carries out parenteral nutrition support to provide nutrients for the body. At this time, the survival time will be prolonged and he will not die in a short time. However, if the patient is in a serious condition and has poor constitution, he will not carry out parenteral nutrition support, resulting in a lack of nutrients in the body, and cancer cells continue to proliferate, consuming a large number of nutrients in the body, which may shorten the survival time of the patient and cause death in a short time.

Some patients will experience depression and anxiety during the illness, and timely communicate with their families, which is conducive to alleviating bad emotions and cooperating with doctors for treatment.
