Lauren,
ALL cancer screening, including pap testing, is elective, your choice.
If you don't want to have pap testing, that's fine, it's up to you, and you don't need to explain yourself to a doctor or provide an "excuse". Informed consent is a legal and ethical requirement for all cancer screening.
These doctors have stepped over the line. I'd send them a letter stating you're aware that pap testing is elective and that informed consent is required, you find it unacceptable that you're pressured at every consult. I'd also say make the point that you're entitled to see a doctor without being lectured and pressured about pap testing. Ask them to mark your file, you don't wish to discuss the matter any further.
You could also, mention the Medical Council, that would make them stop and change their conduct. The MC has made it clear that all cancer screening requires informed consent. If it persists, you could write to the MC, they'd have to take action, they've been vocal about informed consent over the last few years.
It should be a scandal that women are pressured into "elective" cancer screening, it's a shame more women don't report this conduct, and challenge the doctor, but most women don't complain, many give in to the pressure, so doctors keep doing it. I think some doctors know the consult room can be intimidating for some women, and they're in a position of power, that can change quickly when you know your rights.
GPs get target payments for pap testing, I consider this unethical, at the very least they should mention this potential conflict of interest to women. GPs may also, get lump sum payments if they get a certain % of women screened, this is IMO, partly why so many doctors seem to focus on this test. Some doctors put the target and payments ahead of individual choice and informed consent, that's unacceptable.
Anyway, you can either send a letter asking them to stop hassling you and/or you could report their conduct. You can also, complete opt-out forms so you don't keep getting letters/reminders about testing, but you'll have to keep doing that, as the hassling starts again in 4 or 5 years time. (so I hear)
Australia is thinking of introducing a UK style call and recall program, I will be speaking to my solicitor if my decision to opt out permanently is not respected. It irks me that I have to opt out of something I didn't join in the first place!
I made it clear to my GP many years ago that I'd made an informed decision not to screen. (decades ago) More recently, I also, declined mammograms. (when I turned 50)
If a doctor didn't listen to me, talked over the top of me, lectured me, didn't accept or respect my screening decisions, I'd be changing my doctor. It's important to find a doctor who'll work with you and respect your decisions.
I've never had a pap test, initially it was the numbers I didn't like, I'm not prepared to accept much risk at all for a rare event, (cervical cancer) false positives, excess biopsies and over-treament are fairly common risks with this testing. 77% is the lifetime risk of colposcopy and at least a biopsy here, while the lifetime risk of cc is less than 1% (0.65%)
Now I understand that I'd be HPV- (like most women) and cannot benefit from pap testing.
You might be interested to hear the Dutch will scrap population pap testing, they'll offer instead 5 HPV primary tests, or HPV self testing, at ages 30, 35, 40, 50 and 60 and ONLY the roughly 5% who are HPV+ will be offered a 5 yearly pap test. MOST women are HPV- and cannot benefit from pap testing.
Also, note the Dutch do not offer HPV testing before age 30 and they have never offered pap testing to those under 30, they protect their young women from this testing. (so do the Finns) About 40% of women under 30 are HPV+ transient and harmless infections that clear in a year or two, by age 30 that number drops to about 5%. Also, no country in the world has shown a benefit pap testing those under 30, the same very rare cases tend to occur whether you pap test or not, but false positives are fairly common - over-treatment can damage the cervix and lead to premature babies, the need for c-sections etc.
Stand firm and remember, pap testing, bowel screening and mammograms are "elective" screening tests that legally and ethically require your informed consent, they are a choice, nothing more.
