Hannah Day, B.C. Girl With Leukemia, Gets Some Good News


A four-year-old Victoria, B.C. girl fighting cancer has finally received some good news.

It's been a long road for Hannah Day, who was diagnosed with leukemia last year after already beating cancer once before.

In an agonizing decision, the family opted for a "Hail Mary" procedure earlier this year, where Ervin donated one litre of her stem cells to Hannah, reported CBC News.

While she's not in the clear just yet, things are extremely promising.

"Big celebration today. Hannah's bone marrow biopsy shows zero traces of leukemia," Hannah's mother, Brooke Ervin, wrote on the Hope For Hannah Day Facebook page.

"We are not out of the water yet and can not return to our Victoria home but this is the best news we can ask for."

Hannah was three years old when she was first diagnosed with a rare form of cancer, according to CBC. She went into remission after undergoing intensive treatment; however, the drug that cured her of that disease is believed to be what caused the leukemia.

For that reason, Hannah's mother remains level-headed about the road ahead.

“We've been told this before,” Ervin told The Province. “We were told she was cancer-free and we were hugely let down when she had the second case.

“There’s still lots that can happen.”
