No, it doesnt cause cancer but elevated levels can put you at a risk of cancer

Dr. Yusuf Suggests...

Take a Anti Ds DNA test Test or Take a APOLIPOPROTEIN EVALUATION PANEL WITH LIPOPROTEIN A Test

Hello doctor, I had ankle swelling and pain, as well as finger pain. I consulted an orthopedic doctor, who tested me and found high uric acid, low ESR, low vitamin B12, and low hemoglobin. The doctor prescribed some medicines. I would like a second opinion. Are these tablets safe, and do they contain steroids? I have attached my report and medicine prescription.
