I don’t know, have to ask my Oncologist, was diagnosed with stage 4 Coloncancer in January 2018., had surgery, colon resection, liver resection, and part of my pancreas removed, followed by an aggressive chemo treatment, at the moment, 2 years later I am still in remission. Except they discovered a cyst in my left kidney that is slowly growing, will have an MRI in two weeks to see if my left kidney should be removed or remove the cyst by Ablation. They don’t know if the cyst is cancerous or not. I am now 82. In good shape , swim in the lake, live independent don’t feel anything abnormal . I am getting a bit anxious about the results of the MRI.
