My daughter's previous caregiver was diagnosed with cervical cancer after what was to have been her last-ever PAP smear last year (she will be 70 next birthday). However, what she told me was that women between 24-30 (or sim... I can't exactly remember) are in the highest-risk age group for developing cervical cancer. (Ironic then that I have just returned from the mailbox with a letter from my dr saying that my smear is OVERDUE (that was also highlighted lol)...and here I am actively avoiding going...).
p.s. here in NZ we have smears every 3 years unless something abnormal shows up...and we just go to our regular dr, not a gyn.
