(Feel free to tell your own story. This is just a suggestion.)
I have a rare, frequently incurable form of ovarian cancer. In (Month) I'm celebrating my [insert celebration]. It's a bittersweet time as I am grateful to be here, but worried about what may come. Currently, there is no reliable cure for low-grade serous carcinoma. Treatments can put women in remission for a time but for at least 85% of women the cancer will come back. But we can change this. I'm hosting a fundraiser to raise critically needed funds for research.
For my [insert celebration], the best gift you could give is hope for my future. Hope for more time with my friends and family. Please give what you can to help fund research for my rare cancer. It would be the best [insert celebration] present you could give me and other women around the world with this cancer.
