Biologically trans women are trans women, they have very little in common with cis men other than chromosomes, they’re not the same as cis women entirely but have far more in common with them.

The average trans woman has had her T levels nuked for decades, usually below cis women leveks and E levels same as a cis woman, their bodies are completely different including their genitalia most of the time.

As far as the actual medical truth of the matter we are not cis men, I don’t have to worry about testicular, prostate or penile cancers but I do have to worry quite a bit more than a cis man about breast cancer for example.
