Thank you for that very thoughtful and insightful response. Everything you said makes sense to me. I wasn't fearful of surgery until I lost my high school best friend last year. He had a routine colonoscopy that resulted in a blood clot that caused a stroke and death. There is a reason we have to sign off on all of those presurgery documents.
As far as where I read about my biopsy possibly not being classified as cancer, it was here:
www.jcancer.org/v08p2885.htm
PUNLMP was created as category of neither benign nor intrinsically malignant neoplasm in the 2004 WHO/ISUP classification system [8]. Accordingly, PUNLMP should not be regarded as cancer, which has psychosocial and financial significance. However, several previous studies showed that PUNLMPs could recur in a substantial proportion of patients [9, 14-18, 20-22]. Notably, some studies also represented that PUNLMPs had a low, but definitive risk of progression to a higher grade or stage lesions [14-16, 18]. Subsequently, the criticisms evolved that PUNLMP should be qualified as a carcinoma and that all PUC should be categorized as two groups (LG and HG) [4, 8]. In addition, several studies demonstrated that a low level of agreement in the histologic distinction, or no significant prognostic differences between PUNLMP and noninvasive LGPUC [14-16, 22].
Sounds very controversial!
I didn't have much doubt that I would do the surgical biopsy, but I'm trying to cover all my bases.
Thanks again,
