I have developed psoriasis already and i'm afraid i will get hodgkin's disease from this. what are the risks involved?

See details: Whether there is an increased risk of lymphoma related to psoriasis remains very controversial. If there is an association, it is with the people with very severe skin involvement. The issue is further complicated by the fact that meds used to treat psoriasis may increase lymphoma risk. In any event, the risk is extremely low. You have much greater worries in life than this issue.
