When four-year-old Alexandria Hauser was diagnosed with stage 4 cancer on Thanksgiving Day it affected everyone in her life, but her mom exclusively tells RadarOnline.com it's her “babygirl's positivity” that's keeping everyone strong.

Katie Hauser, a single mother of two from Long Beach, California, explains the chemotherapy, surgery, head shaving and so on that her daughter has already endured -- and what the future holds for them.

"Alexandria was diagnosed with stage 4 cancer on Thanksgiving Day. We were told it 'seemed like' a Wilms' tumor, which is one of the most common cancers for children; kidney cancer. After many tests the diagnosis was confirmed," Katie told RadarOnline.com.
