The girl is Alice Pyne and she lives in Ulverston, Cambria, England.
In her blogspot profile she says, "I know that the cancer is gaining on me and it doesn't look like I'm going to win this one."
Alice created a bucket list that she is looking to conquer which includes "to swim with sharks," "to stay in a caravan," and "to be a dolphin trainer."
On Wednesday, her plight and her list became known worldwide thanks to a hashtag and 140 characters.
Due to the multitude of Twitter users hearing and sharing Alice's story, #alicebucketlist became a trending topic spanning from cities across the seas and from celebrities to average Joes.
In her blog, also called "Alice's Bucket List," Alice wrote, "Oh dear and I thought that I was just doing a little blog for a few friends! Thank you so much for all your lovely messages to me."
She said that her mom, or "mum," was trying to respond back to all those who contacted her, but the outpouring of support and concern became so overwhelming that a group of friends have joined in to help reply.
From ABC News' Terry Moran to Eagles' Jeremy Maclin to actor Channing Tatum, #alicebucketlist was tweeted and retweeted over and over again.
By 10:00 p.m., it was the fourth trending topic in Philadelphia.
The word was soon spreading on Twitter that the goal wasn't for Alice herself to become trending, but for her goals to be known.
She says her mission is not for monetary donations through PayPal or of that sort, but to fulfill her bucket list and to get the word out for bone marrow donors.
As for the rest of her list, it includes meeting the English band Take That, having a back massage, and acquiring a purple iPad.
