Hi Linda, it is like being in a scary fog the first days, and I can understand your concerns about your heart. A friend of mine was monitored very closely due to her heart. She had a reaction to her first chemo, and it was stopped immediately with oncologist there on site straight away to treat her. She was in very safe hands there. My advice is to ask lots of questions and take a support person with you to each treatment. Be ocal, and discuss your concerns with the docs and nurses. Sending you a big cuddle, Trace ??????
