> if the problem is tumours
Google paraneoplastic syndromes. Cancer is rarely a problem of just tumors.
> just "laser" all the tumours out and problem solved right?
No. The tumors don't just evaporate. The treatment causes tissue necrosis. Your laser causes inflammation. Even the high tech IMRT you're picturing has those problems.
>Metastatic cancer is defined by essentially there being too many things to hit though,
Metastasis as a concept is fairly meaningless in how you're using it. There are so many more factors in treatment of various cancers that have nothing to do with the distribution. There's a lot that clinpath looks at and frankly I care much more about what's on those reports than playing where's Waldo with nodules. Frequently we assume micrometastasis just based on the cell line or other characteristics.
> therein lies the entire detail
So no.
> you can't treat someone faster than they die of either the cancer or the treatment.
Again far more consideration goes into it but I'm losing my desire to debate these contrived simplistic takes.
