Research: Looking for oral cancer patients with history of Lichen planus, leukoplakia or nail psoriasis.

Hello, I am a oral cancer survivor (3yrs) and looking for people with similar history as me.
I was 1st diagnosed with Lichen planus in the tongue, one and a half years later I had tongue cancer stage 4, it had spread to the liphnodes. I went through surgery, tongue reconstruction, radiation and chemo. I had psoriasis in the nail for the past 6 years and I am always wondering if there is something going on with my immune system.
Thanks
