More than one surgery?

Hi there I haven't posted in a few months but was hoping someone has an answer to this question. My mum's tumour in her sinus cavity was not completely removed due to the location mum had 5 weeks of radiation in Nov 09 not a high dose because of the location of tumour that was left. Well now the bugger has come back my question is can the ENT keep removing the tumour if it keeps growing back? Also anyone know if Chemotherapy will do anything for the tumour? I am staying positive. Thank you everyone : )
