Chemotherapy is one of the important treatments for cancer and is a systemic treatment that inhibits the growth of cancer cells by producing toxic effects on cells through chemotherapy drugs. This treatment has certain toxic side effects, including hair loss, nausea, vomiting, weight loss, mental discomfort, poor appetite and so on. During chemotherapy treatment, patients should wear loose clothes, keep their mood relaxed, eat easily digestible food, and take timely symptomatic treatment if chemotherapy side effects occur. At present, there are more drugs available for symptomatic management of chemotherapy side effects, which have largely reduced the pain of chemotherapy.
