My cousin sent us this essay when my husband was diagnosed. The doctors have never mentioned a "time left" number... have always said, we'll do this chemo until the cancer shows resistance, then we'll try something new. It's working so far... though I'm still hoping he can regain some energy to enjoy life a little more. He is not eligible for surgery because of the spread ... but maybe that can change too.
Thanks for sharing the statistics essay. It was good to read it again.
