Hello. After working as a swim coach for indoor pool YMCA. After the Pandemic., I developed Salvary Gland cancer. It has been in my system for a few years which is now in my bones. Tumors in my glands. Caused by chemical exposure over the years. Rare cancer. Is it possible that 18 years exposure to chlorine clouds indoors caused it? I stopped swimming in chlorine pools in 2016. I coached swim teams, both master and children. I am still a coach but been on medical leave.
