Biologics

Hi everyone i am currently taking aciterin i have only been on it a few weeks my psoriasis is not as flaky but still bright red. However whilst i was at my dermatologist appointment earlier she said i more than qualify for biologics however she did tell me there is a massive risk with this. This medication can bring on cancer and is an immune suppressant. It really worries me. Has anyone had any issues whilst taking this? And is the risk worth the reward.
