Repeating what I think is a key line: one high-resolution DNA-sequencing study of breast cancer last year couldn’t find two cells within one tumor that were genetically identical
As a layperson, I find that to be a very surprising and profound discovery.

One recent study of kidney cancers found that no two patients had exactly the same set of genetic mistakes; in fact, no two tumors within the same patient had the same mutations. Taking it one step further, one high-resolution DNA-sequencing study of breast cancer last year couldn’t find two cells within one tumor that were genetically identical
I’ll bet that DNA repair mechanisms are switched off in most cancers, and this allows more mutations to happen.
A bow??????
