 If you have a cancer diagnosis that's considered metastatic or stage 4, there's a whole list of treatment options that cannot be applied to potentially very effectively controlling that cancer unless you have something called next-gen sequencing or NGS. This molecular or genomic profiling basically identifies a whole bunch of specific targets that can be attacked with anti-cancer therapies, a lot of which are oral and none of which are usually that general cytotoxic chemo. So if you have stage 4 cancer and you have not gotten NGS, it is something that is not only oncologist recommended, but NCCN guidelines recommended to get that profiling to be able to treat your cancer potentially more effectively.
