Thank you very much for the responses. Really appreciate you taking time to respond and enlighten me. We are planning to see 2 more oncologists tomorrow for their opinion. The original doctor who operated on the turmor seems very money minded and all he seems to want is to operate again.
Here some addtional information i could find based on looking at his discharge reports and latest biopsy report. The surgery was done on right side and the recurrance is on the left now.

08/11/08
Final diagnosis
Squamous cell carcinoma grade 11 - right lower alveolus
Surgery: Wide excision of right side slveolus lesion + right mrnd type 11 + modifeied hemo mandibulectomy + free fibular flat repair
Chemotherapy : 7 weeks of Cisplatin
Radiation : IMRT, dose : 5880cgy for 28 times 5 days a week, 1000 cgy 5 times a week for 5 days. In total he got radiation for 33 times ending on 11/05/08

Latest biposy report suggesting recurrance 02/13/2009 on left side.
Left submental area - Smears ad cell block sections show features of a squamous carcinoma - consistent with recurrance in a known case of carcinoma right alveolus

He is 58 years old and has diabetes.

I will share more information once we sees the other oncologists tomorrow. Thanks for the reponses i have got again. I trust the information i see getting posted on this forum than the half baked money minded reponses we have been getting from the doctors we have seen so far.
