Gabby Thomas experienced a major health scare just three weeks before the Tokyo Olympic trials in 2021. "I did have a slight hamstring injury strain, and I got a routine, like, MRI for that," Thomas, 28, explained on "The Squeeze" podcast on Wednesday, August 13. "And in the MRI, they found a mass on my liver that honestly, for me, like, I read so many health research papers. I remember thinking, 'It's probably fine.' I think most people have masses in their bodies that they will never be aware of because they don't get MRIs as frequently as athletes do.
