The Cancer Society says yesterday was a momentous day but there's still a bit of uncertainty around Pharmac's funding boost.  

The Government's committed $604 million, taken in advance from next year's Budget.  

It will cover the funding for 54 new medicines, including 26 cancer treatments.  

Cancer Society chief executive Rachael Hart told Mike Hosking that it's been an incredibly stressful time so the news brings some relief, but the uncertainty doesn't end.  

She says cancer patients still don't know when the drugs will be funded, and when you're shelling out thousands of dollars a month, every month matters.
