how does cancer return back more aggresively after treatment?

It doesn’t always, even if it comes back, but it can.
The best answer I see here is from u/LogSouth2717.
Basically, a few things. We may have treated the cancer almost perfectly, but not quite, according to type. There are SO many types, grades, stages, locations, etc. As he said about NSCLC, doctors can select just barely the wrong type, or insufficient treatment and kill all but the worst little tiny bit of the tumors.
Next, some tumors do develop resistance to drug therapies, if they don’t get the whole thing the first time.
Also, remove a tumor and do the chemo, and hope you got all the “seeds”. If you didn’t, they will pop back up rapidly, and at the same time.
Whatever genetic or evironmental factors lead to the tumors are still there, and cancer treatments themselves can be pretty hard on the body, leaving you less resilient against the next one. It’s common for people to develop a new disease after being treated for the first.
