BEIJING, June 4 (Xinhuanet)-- Ten-year-old Hannah Powell-Auslam from Southern California shocked the world when she was diagnosed with breast cancer in April. But even after her first chemo treatment recently, the girl is upbeat and determined to beat the disease.

    "I always try to look on the bright side with everything," Hannah---the fifth-grader at Escalona Elementary School--  said ABC's "Good Morning America" in an interview that aired Wednesday.

    Hannah, according to her family, is the youngest known girl to be diagnosed with breast cancer after complaining of an itch in her side in April. Her mother discovered a lump, and that led to a diagnosis of breast cancer.

    Her family said she was diagnosed with invasive secretory carcinoma, a type discovered in children in the 1960s.

    "You feel like you're sick all the time," Hannah said of the effects of her chemotherapy. "You just want to go lay in bed and be in your closed-off little box."

    In a desperate attempt to save Hannah's life, doctors removed her left breast on May 7.

    The show filmed Hannah at home getting her head shaved rather than waiting for chemotherapy to take its toll. Other family members--her father, grandfather and younger brother-- got buzz cuts, too, in solidarity.
