Honestly, I avoided it for so long but it was the best decision I could have ever made for myself, and it saved my life in a much more literal sense than most trans people say since it lead to them finding my cancer early enough to treat due to all of the monitoring of my hormones that I was under.
As to the cancer, I'm definitely hopeful. I've been basically getting injected with copious doses of poison for almost half a year now, so for the traces of cancer that were left post-surgery my prognosis is thankfully very positive!
