Actually, it's talking primarily about the link to PML, which is much worse than cancer. It's a progressive degeneration of the brain which is related to a common virus. Nearly everyone has the virus, but most have perfectly normal lives with no problems from the virus. Suppressing the immune system radically increases the chance of developing PML from it, and that has been linked especially to Tysabri. PML is deadly and there really isn't any effective treatment for it.
It really is up to us to try to do our homework and make the best decisions we can for ourselves. For some, the relief provided by Tysabri is worth the risk. Quality of life can be as important as quantity.
