My husband is undergoing chemo combined with Avastin and Oxlyplatin for colon cancer.  His hemoglobin dropped to 8 and his oncologist wanted to give him a blood transfusion which he refused. After taking Carao for a week and a half his hemoglobin went up to 12.1 and has continued in the 11.1 - 12 range since then. As a result he has experienced a noticeable increase in his energy levels. Thank you so much! Sandra FL USA
