It wasn’t the first time Miguel was treated at St. Jude. He was diagnosed at 5 months old with bilateral retinoblastoma, a rare cancer that affects the thin membrane on the back of the eye that senses light and color and sends messages to the brain that allow for vision. Miguel’s doctors used a combination of chemotherapy, proton beam radiotherapy, laser treatment and cryotherapy to combat his condition, which helped preserve the vision in one of his eyes. He finished treatment for eye cancer in 2020.
