Transgender women receiving hormone therapy may skew artificially low on prostate cancer screening tests, thereby providing false reassurance and potentially delaying diagnosis and treatment, according to a recent study published by Nik-Ahd et al in JAMA. The findings indicated that transgender women and physicians should interpret standard screening guidelines with caution.
All I’ve got is anecdotes, but as I understand it, trans women are less likely to get prostate cancer in the first place. Personally, I don’t know any trans women that have prostate cancer, and given how many older trans women I know, that suggests it’s less common than you’d expect in cis men.
However, it could fit that those of us who do get prostate cancer are at a more severe level before it’s detected. In my years in the trans community, the only times I’ve learned of trans women with prostate cancer is when it’s been advanced. But those are all second hand stories and blogs/news articles etc.
