Yes, I am being treated for IDC - breast cancer. I had chemo for 6 months and now taking Herceptin iv every 3 weeks. I will have another Herceptin infusion on Monday.After my first Herceptin infusion (three weeks ago), I have been experiencing nausea, vomiting, flu like symptoms with coughing, sneezing, raspy voice and this has lingered on since that first Herceptin.My question is this:For the last two days, I have been coughing up very thick and blood tainted sputum and this evening, I had a large diaharea and the stool was very black. I have not eaten anything black to cause this either.Should I be alarmed and contact my doctor immediately or just pass it off as my being an alarmist?
Dear Ma'am, Sorry to hear about your problem. You should immediately consult your oncologist as the black stools are due to bleeding inside your stomach and that is the reason you are spitting out blood as well. This can be a side effect of Herceptin and the other chemotherapy Chat Doctor.  Hope you get well soon.
