John Cena opens up about his past skin cancer diagnosis, emphasizing the importance of wearing sunscreen. Despite growing up without sunscreen in Massachusetts and later falling in love with the sun in Florida, Cena neglected to protect his skin. After having cancerous spots removed from his chest and shoulder, Cena now prioritizes daily sunscreen application with a high SPF. He urges others to take the time to protect themselves from the sun's harmful rays to avoid potential health risks.
