A 4-year-old U.K. girl whose father wrote a nationally heralded blog about her brave battle against a rare childhood cancer is once again battling the disease, the Telegraph reported on Tuesday.

Samantha Hughes of Heanor, Derbys, England, was diagnosed in October 2005 with neuroblastoma, a cancer of the nerve cells. Following removal of the tumor, a bone-marrow transplant and chemotherapy, Samantha was believed to be in remission.

Her father, Neil Hughes this week said he felt numb at the setback, according to the report.
