In 2012, Mack Horton was an Olympic hopeful thinking nothing of the moles on his chest.
But in 2016, a fan noticed something worrying. One of his moles had gotten darker and larger. The fan immediately knew something was wrong. Discolored and growing moles are a sign of skin cancer, which can lead to cancer spreading throughout the body.
The fan wrote in to the swim team doctor and voiced their concerns. Mack Horton went to the doctor and it was confirmed: his mole was cancerous.
Mack Horton recently had surgery to remove the mole. He posted a picture online with a large bandage over his chest. He captioned it, "'Shout out to the person that emailed the swim team doctor and told me to get my mole checked out. Good call. Very good call."
Australia has one of the highest rates of skin cancer in the world due to their overexposure to UV radiation in sunlight. People are advised to check for new spots that might appear, as well as monitoring existing spots for any changes in color, shape, or size.
We're happy that fan was able to spot Mack Horton's mole! And we're sure he is too.
