Do not know what combination with Avastin your daughter is taking but I have heard that nosebleeds are a part of Avastin.. I took carbo taxol and was constantly tired and the usual problem is low red blood cells.. I had several blood transfusions and then felt much better... She should talk with her oncologist on her platalet count and red blood cells... chemo is tough.. I am twice your daughters age and it took me almost a year to feel like normal again... my last chemo was 14 months ago.. good luck..
Definitely speak with her doctor about low blood counts, sometimes bleeding indicates low platelets. Shortness of breathe is also a system of low blood counts. I have had several blood.. platelet and red cell transfusions and afterward felt sooo much better. Hope this helps, good luck. Withe
