Any one claimed total and permanant disability through superannuation?

I have been able to claim this as I have secondary breast cancer. My oncologist signed all the necessary forms. It was daunting to see on the forms that I was expected to ave a life expectancy f less than 12 months but here I am 14 months later. I know I will die from this crappy disease but we don't know when and it was a small consolation t get the insurance money and pay off the debts.
