ANSWER 1: This question is alarming.
You are right to feel uncomfortable with this, and you should report this psychiatrist to your state department of health or other medical regulatory board, depending on your country.
A psychiatrist should refer you to a gynecologist or general practitioner for a breast exam. This sounds predatory.
ANSWER 2: It depends… if you are a patient in a Psych ward, and complain of nipple discharge, then yes, the psychiatrist should check, and then consult ob/gyn. There are tumors and drug side effects that can stimulate milk production, and that would be an important thing to verify. Outside of a psych ward, it would not be appropriate, they would just refer you to an ob/gyn.
You mentioned hormonal imbalance, but a few times I saw breasts that were infected to the point that if they weren’t treated quickly, the patients would have gone septic and possibly died.
A psychiatrist is a doctor, and even outside of the psych ward there could be scenarios when it would be appropriate, but it would definitely have to be with a female chaperone, and only with your consent.
ANSWER 3: I am not a physician, so I really do not know the answer to this. I did not just turn down the request to answer this because I wanted to let you know that this IS a valid question, but that only a physician would have the answer to it.
I do know that some medical conditions that are driven by hormones – like PCOS – cause depression and anxiety. I do not know enough to know if “checking “ breasts could tell a physician that you are more likely to have it and that this would then merit a referral to a specialist.
ANSWER 4: Hormonal imbalances are checked by blood tests. This doesn’t sound right. Get the h#$% out of there now!
ANSWER 5: No,no.no.
A psychologist doesn’t do breast exams. There is no way to check hormonal imbalance just by groping.
He should be reported
VERDICT: Ideally a psychiatrist shouldn’t be checking your breasts. But in case he wants to find out any abnormality, it is advised to involve an Obs Gynae in the process. Moreover, a male doctor wanting to investigate your privates should always have a female attendant with him.
