Prognosis
Psoriasis is typically a lifelong condition. There is currently no cure, but various treatments can help to control the symptoms. Many of the most effective agents used to treat severe psoriasis carry an increased risk of significant morbidity including skin cancers, lymphoma and liver disease. However, the majority of people's experience of psoriasis is that of minor localized patches, particularly on the elbows and knees, which can be treated with topical medication. Psoriasis can get worse over time, but it is not possible to predict who will go on to develop extensive psoriasis or those in whom the disease may appear to vanish. Individuals will often experience flares and remissions throughout their lives. Controlling the signs and symptoms typically requires lifelong therapy.
According to one study, psoriasis is linked to 2.5-fold increased risk for nonmelanoma skin cancer in men and women, with no preponderance of any specific histologic subtype of cancer. This increased risk could also be attributed to antipsoriatic treatment.
