BS!
It’s well known and established that any hormone replacement therapy greatly increases incidents of cancer - it’s also partially why it’s banned in athletics.
Supplementation for those in need is one thing but supplementing because you think your physical sex is wrong is retarded to the 10th degree
HRT does not GREATLY increase incidents of cancer. Why would it? If it is the same as what the subject produces but not enough of it, the result should be negligible. It's banned in sports for performance equality not health reasons. Arnold Schwartzenegger took massive amounts of testosterone to define his physique and he's still living and smoking cigars at 76.
Gender is determined by what you have between your legs - not by what you have between your ears!
