Patient Reviews
Feb 02, 2023
I was diagnosed with a very large mass of cancer on my Spleen. At St. Lukes Dr. Mark J Fesler recommended a treatment that was relatively new. It was a six month treatment to diffuse large B Cell Lymphoma. After only 3 months the mass had receded by 60 to 70 percent. After the treatment was over my cancer was gone. This was started in about 3-1-2022 and over around 9-1-2022 and as of today I still have no sign of it returning. Dr. Mark Fesler is a Specialist in this field and if you have cancer I highly recommend you seeking his advice. He saved my life and he can do the same for you.
