I believe side effects management should be a conversation before you take your first treatment. Everyone has some side effects from chemo, ranging from very mild to very awful.
Asking your doctor or oncology nurse about what you should do if you have problems and who do you call if you need help is a good opener for that conversation. Sometimes it is helpful to have a list of questions, so that after the doctor tells you the plan, you can check and make sure all of your questions are answered.
Sometimes fighting cancer requires us to take strong drugs and we need to know that we can rely on our doctors if we have a problem.
Are you comfortable having this conversation with your doctor?
