screening for endometrial CA
US and endometrial biopsy
colon screening
what age do you start US and endometrial biopsy screening for endometrial CA
30-35
what age do you start colon screening for endometrial CA?
20-25 every 1-2 yrs or 5yrs before earliest cancer in family
what do you use to diagnose endometrial CA in symptomatic ppl w/ negative endometrial biopsies?

3 ways to screen for ovarian CA
CA125 testing
US screening
annual rectovaginal pelvic exam
when is CA125 testing elevated? what does this mean for how we use the test?
elevated in stage 1 cancers
not good for general population– poor specificity in premenopause
ovarian CA screening recommendation if no fam hx or 1 fam hx
fam hx + annual rectovaginal pelvic exam
ovarian CA screening recommendation if 2+ fam hx
