Hello, I Had Few Episodes Of Tonsil Stones, But For

Hello,
I had few episodes of tonsil stones, but for the first time it's different. Normally they are 1 or 2, white/yellow, and they are easy to take off and paste consistency. Today I see I have more, they are white/yellow with brown/black and they are kind of attached to the tonsil. I get one out and its consistency looks like more like gelatine, no paste at all. Should I go check for possible cancer?
Thanks in advance.
