While there’s no definitive proof that psoriasis causes skin cancer, some studies suggest a connection. Some studies suggest that people who have psoriasis may be slightly more likely to develop skin cancer than those who don’t. It’s thought that the reason for this is that psoriasis causes skin damage, making it more susceptible to changes that can lead to cancer. It’s unclear whether the increased risk of cancer is caused by the disease itself or by common treatments for psoriasis, such as immunosuppressive medications and ultraviolet (UV) treatments. According to a 2020 review, some common treatments may increase the risk of skin cancer in nonmelanocompetents. These treatments include Psoralen PUVA therapy and Ciclosporin, TNF (Tumour Necrosis Factor) inhibitors. Or, the disease’s chronic inflammatory mechanisms may cause increased cancer risk.
