My battle

@dorycheeto: I welcome you on behalf of Mayo Clinic Connect; I'm glad your search brought you here as I truly feel you will get the objective information you're seeking.

I'm sorry to hear you've been diagnosed and treated for SCC (squamous cell carcinoma) in addition to treating for psoriasis. In my past work in healthcare, I had been quite familiar with Skyrizi, a biologic which has been known to cause rashes or allergic reactions in some. However, to my knowledge and upon research including on drugs.com and various studies, there has not been any definitive correlation to cancers per se. There was one very detailed NIH study that I'm wondering if the site or forum you found may have had people conclude Skyrizi was the cause of their SCC. When searching for such answers online, it can be confusing to find reliable information so I'm uncertain what their reports were based upon.

Have you discussed your concerns about this prescription medication and/or psoriasis and the development of SCC with your rheumatologist or healthcare provider?

Susan makes good sense. Doing some footwork would be good. I have not heard drugs causing skin cancer. My family has most physical characteristics causing skin cancers. Mom and Dad both had either squamous or Melanoma or both. Squamous is treatable before it metastasizes. So many studies require a significant number of people but that is not to say the NIH study did not have people who may have been more susceptible to skin cancers. Honestly, at 60 i would have thought a skin cancer besides basal skin cancer would get me. No, breast cancer then MDS.
I hope you have spoken to your medical care provider.
