First I want to say I see nothing on the internet about fenzapro 222mg which concerns me. I will say I have been taking Ivermectin for 3 months 18mg and for the past 4 days fenzapro. I had a ct scan showed 8mm nodule, 3 weeks later 10 mm nodule and the shape and the size and how fast growing they were sure it was cancer. Its not. I do have a tumor on the base of my skull this will tell if this really help.I wish I could find more info on this
