What are the side effects of chemo therapy?

Dosage of chemotherapy can be difficult: if the dose is too low, it will be ineffective against the tumor, while at excessive doses the toxicity (side-effects, neutropenia) will be intolerable to the patient. This has led to the formation of detailed "dosing schemes" in most hospitals, which give guidance on the correct dose and adjustment in case of toxicity. In immunotherapy, they are in principle used in smaller dosages than in the treatment of malign diseases.
