Low-dose Chemotherapy is being studied/used in the treatment of cancer to avoid the side effects of conventional chemotherapy. Historically, oncologists have used the highest possible dose that the body can tolerate in order to kill as many cancer cells as possible. After high-dose treatments the body reacts, sometimes quite severely. Infections from external causes become a leading threat of death. Some have suggested that the chemotherapy cure is worse than the cancer because of the hair loss and constant vomiting that are so common in chemo patients.
