There are hundreds of organizations actually doing cancer research. If you want to give, just cut out the middle men and write a check to the research organization of your choice. Here in Seattle we have many great research organizations to choose from.

Fred Hutchinson
Benaroya research Institute
U of W
Seattle Biomedical Research Institute
And at the VA Hospital there is Seattle Institute for Biomedical Research
Are all excellent

Just goggle the type of research you want to support and you will find many worthy groups.

I would caution not to get too hung up on what percentage they spend on administration. That number can very easily be manipulated. For example. Some organizations consider rent to be an administrative cost; others charge the grants directly for rent. Total rent cost is the same but in the former the administrative cost rate would be much higher than the other.

Another consideration is depreciation. Research requires some very expensive equipment. One of my clients has a microscope that cost more than $2,000,000. Annual depreciation and maintained on just that one microscope can exceed $200,000 per year. In most instances that cost is considered a cost of administration.
