I looked up what you said the cancer was and it also said it is slow growing and not aggressive. It also said that surgery followed by radiation is best ,but radiation can effect quality of life. It looks as though your mum's case is unusual.
Was there a delay before surgery? Did it recur after surgery?
I have a rare head and neck cancer ,adenoid cystic carcinoma. It is usually slow growing . It was 2 months between diagnosis and final surgery .This was because of PET /ct scan ,further biopsies of suspicious areas and debate of aspects of surgery. I am ok 2 years later .
With my cancer there are some cases where it can be very aggressive.
It can be slow ,then speed up. Still usually slow .
I am sorry about your situation.
