Yvonne: Okay this is a chart of blood – white blood counts that was taken – this is about a year before he started, at that time it was known as STI-571.
Bud: Yes that's it.
Yvonne: And he was in the 35/50,000 range. 60,000.
Bud: White blood count.
Yvonne: And the white blood count which is normally I think it's about 10,000 is about the highest a person would get on it. Then he started taking this STI-571 which is Gleevec™ and about 17 days he was back down into his normal range on his white blood count and he's been normal ever since. And this is just what an important thing – what a breakthrough, I don't know what else to call it.
Professor Charles Sawyer explains that CML stands for chronic myeloid leukemia, which is a blood cancer and it is different from many cancers because it starts very slowly and patients when they're first diagnosed don't have many symptoms.
In this section learn that tyrosine kinases are a family of activator proteins that trigger the cell signaling process leading to cell growth and division.
Conventional cancer drugs are cellular poisons that block replication or some other aspect of cell growth. These drugs affect all cells – healthy or cancerous.
