tongue cancer

my husband had SCC of the tongue in 2008 and had a hemiglossectomy with a radial flap reconstruction radiotherapy (no chemo was needed as his lymph nodes all came clear after removal)
He has been having trismus since then and alot of mouth infections. He had a another biopsy recently and it has recurred at the tip of his tongue now.
Apparently he has to go through the same procedure again.
Anyone been through this ...?? please let me knw he is only 41 years old
