So I thought about it and came up with the "Fuzzy caterpillar" concept. (My scar from the most recent cancer looked like a fuzzy caterpillar, and the first two letters of each word, f and c, correspond nicely with "F*ck cancer.")
So you're supporting the cause and spreading the word - when someone asks, "What's fuzzy caterpillar mean?" you can tell them!
The (albeit minimal) proceeds from the sale of the shirts will be split between charity and the medical bills I racked up during IVF and uterine cancer.
Thanks for the support and spreading the word!
