This is a question for people who are ether doing chemotherapy or have already done chemo.?

I am doing a report for school about the uses of chemotherapy and I was hoping to get some help from you. I thought that hearing it from someone who is doing or already did chemo, would be best. please help me I not only want to get a good grade but I would like to know because I have a really BIG chance of getting cancer, from my grandmas who have already ped on because of the cancer. Thanks for helping!!
