Despite personalizing - or what appears to be personalizing, there is still a hit or miss approach to cancer. They look and say - you have this kind of tumor - so they write up a plan based on previous experience with - this kind of tumor- ie: HPV tumors - BOT tumors - are treated a certain way - Oral tongue a certain way... However what works for one oral tongue patient may not be what works for another - based on genetics, aggressiveness, age and causes of the cancer (smoker? Alcohol use? Etc..) this particular treatment caco is talking about requires freshly biopsied tissue, and they hit it with certain types of chemo to see how it reacts to them, then based on that a plan is built. I have completely over simplified everything here but it is to me far more personalized than the cookie cutter treatments we get - I guess mostly because it involves your actual tissue - and immune system. Good luck caco!!!
