best thing to do so I don't get in any trouble (providing there are no problems after I report to my oncologist,) is to just go back on the 19th or 20th of December, and tell them (My employer) it's a trial work period.
I am just worried about the Insurance, as the medicaid is better I think.

I don't know, also, if I try to work and it IS too hard on me, maybe SS will see that at least I did try, and it will be easier to continue to receive SSDI.
