I have in my possession the ashes of my biological mother, who died of breast cancer. How can I use them to help in my own battle?

Update: I have ordered a replica of the Venus of Willendorf (the earliest carved mother goddess image, and a good resemblance to her), and some purple candles (she used to say that she owned everything purple, but we were allowed to use it), and will be building a permanent shrine to her quite soon.
