Is Enlarged Adenoids The Reason For Snoring?

My husband, who is 38, has a biopsy tomorrow as he has a 'growth' on or around his adenoids. He snores badly, and has congestion problems on a regular basis. he is beside himself with worry. how likely is to be cancer??? I realise that you are not able to answer in definatley, but, could it simply be a case of enlarged adenoids? his tonsils were removed when he was 6, as he suffered from tonsilitis on a regular basis. he also has problems with his ears with constant ringining hi his ears. His wisdom teeth should be removed urgently according to a recent dental appointment and he has problems with his jaw. hope this is helpful information..... thank you.
