"Alice Bucket List" on Twitter, 15-year-old with terminal cancer Alice Pyne reaches out online

(CBS) - Alice Pyne, a 15-year-old British blogger, started her bucket list after learning she has terminal Hodgkin's Lymphoma. "I've been fighting cancer for almost four years and now I know that the cancer is gaining in on me, and it doesn't look like I'm going to win this one," she says on her blog. "I'm hoping to write in here as much as I can and I'm also going to show my bucket list, which I'm trying to get done before I have to go."

Some of the things on Alice's list: to make everyone sign up to be a bone marrow donor, to swim with sharks, to have a purple Apple iPad (mom's going to borrow one), to be a dolphin trainer, to go to Cadbury World and eat loads of chocolate, and to be a trending topic on Twitter.

She succeeded on that last wish. Thanks to tweeters all over the globe, #alicebucketlist is trending on Twitter - just three days after her first blog entry on June 6.

As supporters re-tweet "#alicebucketlist," the cancer patient also hopes to encourage people everywhere to register as a bone marrow donor. "I'm excited about the things I am going to be doing, but the biggest thing has to be all the people who are joining bone marrow donation schemes because of me," Alice wrote in a blog post titled "Oh dear!"

"I can't believe that so many people have taken an interest in my blog," Alice wrote today. "Now for mega exciting news... I'm off to see Take That this weekend, can you believe it?"

Keep going, Alice!
