We are blessed with an amazing surgeon. He said he didn't think an MRI was necessary, and i asked him what he would do if it was his daughter, and he said he wouldn't do the MRI as he is confident it is scar tissue and the feeling slowly coming back into her tongue. But he also accepted she's a scared young Mum, and he could see he could use it as a measuring stick in the future, so said let's do it.
Funny isn't it how she was scared it was the cancer back, now she's been told it's not, she's still frightened as worried it will show up something else. As I said to her, others worry about their health and they've not had what she's had, so perfectly normal to be fearful, as it's still early days for her.

As a matter of interest to others, a friend's Dad had oral cancer 3 times, started on the roof of his mouth, and the last time was 34 years ago! He's now 74 and in great health.

Thankyou again for all your help, and I might post on the caregiver forum, and also a question about recovery. This has been wonderful to find you even if I don't visit often, although i should as I think how wonderful it would have been to have found this when she was going through her biopsy and diagnosis.Maybe I can help someone else.
