Chemotherapy for Cancer Has Produced a Few Dramatic Successes

Chemotherapy for cancer has produced a few dramatic successes. Almost 75% of children with childhood leukemia are completely cured. Hodgkin's disease, a lymphoma, once killed 2 out of 3 patients. Now, a combination therapy of 4 different drugs can wipe out the disease in a matter of months in 3 out of 4 patients, even when the cancer is not diagnosed immediately. Raymond A.
