Why didn't you say so?

Best medical advice I ever got was to bring a man to your appointments

[u/Pure_BTW]

How would you phrase that without sounding hostile? Maybe like “Do you mind making note that further testing was ‘refused’ in my file for future reference?”

[u/bandti45 → u/Pure_BTW]

Sometimes sounding hostile is how it should be. Just saying.

[u/Pure_BTW → u/bandti45]

I agree, but I suppose it’s situation dependent. If it’s my GP I see once/twice a year for a check up, I want to keep a friendly relationship with.

[u/Advanced_Double_42 → u/Pure_BTW]

If they are regularly ignoring you, then that's likely needed to keep things friendly.

Let the file show that the current doctor, <insert doctor name>, has refused to perform further testing

[u/fasda → u/Pure_BTW]

This should be a last ditch thing if your doctor is absolutely refusing to take you seriously. It is asking the doctor to admit in writing that they might be committing malpractice and that they are going to lose quite a bit of money in the near future. The line is a threat, it is hostile.

If you want gentler means of persuasion, I suppose could it be something like, what other conditions could present with these symptoms and are tests for them really that burdensome and would you mind writing it down in case I seek a second opinion?

[u/CitizenPremier → u/Pure_BTW]

More direct than that is probably best. "For future records, please note that I thought it was malignant, but was declined further testing."

[u/Advanced_Double_42 → u/Pure_BTW]

You want it to sound mildly hostile. Formal enough for a corporate email, but clear enough to still show contempt.
