Each can be discussed further in detail now or at the appropriate time, if you have any questions. Certain drugs, like Cisplatin, have side effects that may cause neuropathy (tingling in hands, feet), hearing changes or tinnitus, vision changes that need to be brought to the oncologist's attention when they sart to occur, which can otherwise be permanent.
