Why screen by organ
Most health systems schedule screening by the sex recorded in documents: cervical screening for women, prostate checks for men. For trans and gender-diverse people, this can mean missing important screening or receiving tests that are not needed.
WPATH Standards of Care Version 8 therefore recommend that screening depends on the organs a person still has, their age, history and risk, not on a name, title or identity alone.[1]
What organ-based care achieves
Organ-based care reduces missed screening and unnecessary tests.[1] For example, a trans man who still has a cervix may never be invited for cervical screening because his record says male, while a trans woman still has a prostate even after many years on hormones.
Feelings matter too. Many people avoid check-ups after experiences of disrespect. Respectful, understanding care helps people come back to screening.
Risk is not the same for everyone
How often cancers and infections occur depends on organs, age and exposures; no single figure describes all transgender people.[1] Assessment must therefore be individual.
What determines risk
Risk depends on retained organs, age, hormone use, previous surgery and exposures, rather than recorded gender.[1],[2]
- Cervix: if present, cervical cancer risk remains. Testosterone can thin the tissue and make sampling harder, but screening is still recommended.
- Breast: trans men with remaining breast tissue, and trans women on long-term estrogen, should consider screening based on risk and duration of hormone use.
- Prostate: trans women still have a prostate, even after gender-affirming surgery.
- Anus: risk depends on sexual practices, HPV and HIV.
Start with an organ inventory
A good approach is an “organ inventory” made with your doctor: a private, consent-based record of which organs you have and which have been removed. Cervical, breast, prostate or STI screening is then chosen when indicated.[1],[2]
Providers should use the words you are comfortable with for your body and always explain why each test is suggested.
Testing for STIs at the right sites
STI testing should sample the sites actually exposed, such as the throat, genitals or rectum, in line with CDC guidance. A urine test alone does not cover throat or rectal infections.[2] Many people have a normal urine test and assume they are clear, when infections at other sites were never tested.
Anal cancer screening is risk-based and depends on appropriate follow-up services being available; it is not the same for everyone.[1],[3] People at higher risk, such as those living with HIV, should ask their doctor whether screening suits them.
How we care for you at Dr. Kris Clinic
We provide organ-based screening with respect, using your name, pronouns and preferred words, explaining every test and proceeding only with your consent, in English or Thai. We build your organ inventory together to plan only the screening you really need.
STI testing can be done at several sites according to your risk, and for cancer screening that needs specialised equipment, we arrange referral to LGBTQ+-friendly services.
Frequently asked questions
I'm a trans man. Do I still need cervical screening?
If you still have a cervix, you should be screened as recommended for everyone.
Do trans women need prostate checks?
The prostate remains even after gender-affirming surgery. Screening is considered according to age and risk.
My urine test was negative. Does that mean I have no STIs?
Not necessarily. Urine tests do not cover the throat or rectum, so test the sites where you have risk.
I find internal examinations distressing. What can I do?
Tell your doctor. They can adjust their approach, explain each step, or consider suitable alternative sampling methods.
Screening should match the organs you have and your risk, while respecting your privacy.[1] Symptoms need prompt assessment rather than waiting for routine screening.
