The point of the ongoing discussion should also take into consideration the stage of the cancer and thus how widespread it is. If you had read up re. cancers you would know they exist in different stages, from localised to grossly systemic.

I do know quite a bit about cancers. The ongoing discussion has already taken into account the different stages, as @Bored chemist says.

I think you misread me. The post is about a "probe". A "probe" is an instrument that "probes", it determines dimensions, it is executed as an exploratory exercise. Treatment is something else. Perhaps the post was misworded, however I can only call a spade a spade on this one and give the OP the benefit of the choice of words.
