Default Genomic variation within an individuals tissues

Hi!

I am trying to find information on how much genetic variation one can expect between different tissues within an individual. For example, how different is breast tissue from blood? I know this has been described for methylation and expression but I am interested in DNA differences.

I am asking because when doing tumor/normal variation calling you want to use the same tissue as a normal that the tumor originated from but barring that, is it ok to use some other tissue? How many more variants can one expect if not using the same tissue?

If anyone has some insights or articles I would much appreciate it.
