A toddler named Chase was diagnosed with retinoblastoma, a rare form of eye cancer, after his parents noticed a subtle difference in one of his eyes. The diagnosis came after Chase had already suffered a detached retina, resulting in the loss of sight in that eye. The family made the difficult decision to have his eye removed, only to find out afterwards that Chase did indeed have cancer. He is now undergoing treatment, including chemotherapy and targeted proton radiation in the United States. The family is raising money to cover the costs of their trip on GoFundMe.
