I think it was because my doctor feels the nodule was meeting all of the criteria of a malignancy. I told him if I am malignant, then I want it removed ASAP. His response was, then we'll go straight to biopsy. My nodule did not appear is a June CT scan but appeared in an August CT scan. I was having CT scans for an unrelated heart condition. I think the sudden appearance of the nodule was also a factor.
