Like if you detect it early enough, I know you can remove it. But what is the point that it can’t just be removed, and why?
In: Biology
You might have put this all together by now, but I don’t see this stated quite this plainly, but think about how big a single cell is.
All large cancer tumors start from a single cell, and if you miss just one cell it will multiply again.
Even when we generally start saying that someone has recovered from cancer, technically we can’t say for sure that they are fully cured because it is impossible to be for sure that every single cancer cell has been removed and destroyed. All that can be said is it is no longer detected. You will have to go in for regular screenings to check for cancer again just to see if it started to regrow. And it can take years or even decades for it to reappear.
Once you have cancer, until you die it can not be said with 100% certainty that every cancer cell was killed. It is something you have to carry for the rest of your life. The only comfort is that the longer you go without it cropping up the less likely there’s any left. But no one can be sure.
