Thanks! Saw RO and hospital dentist today. Former said I could have an extraction because the radiation (on that side?) was less than 50 gy. But I didn't have an extraction, just a filling because the tooth has settled down and it's quite a useful one for my limited eating. We've bought it a little bit more time.

The bigger part of my life right now is getting from appointment to appointment in car to Park & Ride, then buses with lots of walking thrown in.

1996, ovarian cancer surgery + cisplatin and taxol.

October, 2009 recurrence in scar tissue, T1NOMO. Free flap surgery from left wrist - neck dissection. 63 year old New Zealander. No chemo, no RT.
February, 2014. New primary in left buccal mucosa. Marginal mandibulectomy, neck dissection, right arm free forearm flap. T1N0M0 but third occurrence and some areas of concern: RT started 8 April and finished 19 May.
