Has anyone acquired strep throat after having throat cancer?

I had bilateral tonsillectomies with positive cancer on the left in August of 2012.

I had a cold, which come along with a sore throat, but now the cold is better (almost gone) and my throat has gotten worse.

I just looked in the mirror and I can see white patches in the back of my left side. This is the same side as my cancer. I'm starting to freak out a bit.

Should I contact my doctors on Monday?
