@abartels ..
In my absolutely worthless unprofessional feedback, I would say time is wasting. 2.9cm is substantial, the imaging report describes it as high risk, and you have had two previous malignancies. I echo others here suggesting you get it done cowboy. Soon. Consider a second opinion.

Just to confirm we don’t have math confusion translating mm to cm, 2.9cm is 29mm. Mine was 14mm and they were in a hurry to get it out. I’m struggling to grasp your doc’s thinking. If yours is in fact almost 3cm, I strongly suggest you seek a second opinion - you could pick another specialty if you are concerned about offending your doc. Like an oncologist.
