Thanks Sharlee,
Finally, I've heard from a person who has undergone the same experience (many thanks to your reply)..

I'm quite ignorant on the intricacies of treatment though I could find out a few things of relevance by surfing through various sites. I'm sure that the TNM specifications are still to be worked out for my mother and the few things I see are (1) tumor grade (G1) and (2) no enlarged lymph nodes.

However, I'm quite unaware whether they indicate anything (based on your response).. besides, the surgeon did prescribe the Radiation Therapy but he reiterated that the cancerous ulcer has been removed and radiation therapy shall still be done.

Does the absence of enlarged lymph nodes point to anything? --OR-- are there more tests (besides, pathological review) to be conducted to work out the staging?

Thanks & Regards
