The bird's-eye view IMO is less important for us than a closeup on PCa. And here we should distinguish your inherited risk factors (
germline DNA testing of your blood or saliva) and what
genomics testing can tell you about
the actual PCa that you develop (Decipher, OncotypeDx, etc.), which usually looks at your lesions' RNA.
Many folks aren't aware that you can download a file of your complete DNA profile for free from any of the major testing sites you've used, like Ancestry.com, 23and Me, etc. and upload it to promethease.com. There, for $12, they will run a medical literature search and give you a very detailed report of your protective and risk factors (e.g., BRCA1 and BRCA2) across all diseases.The association of BRCA1 and BRCA2 mutations on prostate cancer risk, frequency, and mortality: Systematic review and meta-analysis [2018]
