I am not a physician so I'm answering this from the perspective of a biologist. Chemotherapy can certainly have long-term side-effects. Most of them are directly related to the cellular targets of the drugs (i.e. the pain or tingling in the hands/feet seen in some cancer patients is caused by specific types of damage caused by the drugs used). The question is not detailed enough for me to research an accurate answer. What is the nature of the problem? The treatment received? The cancer? etc. Sorry I can't be of more help on this.
