You can have a look at the Personal Genome project from George Church. It's all open data from willing participants. I don't think they have cancer genomes but I think you should be able to download germline genome data and phenotypes / traits.
Sharing Personal Genomes
The Personal Genome Project was founded in 2005 and is dedicated to creating public genome, health, and trait data. Sharing data is critical to scientific progress, but has been hampered by traditional research practices—our approach is to invite willing participants to publicly share their personal data for the greater good.
