Leaning forward for breast examination

Is it really a thing doctors ask to do?

I wasn't asked to do so. Not even by my girlfriend, who checked me everywhere in different play exams and surgeries Thats why I am surprised.

But honestly I really want to know, what's the purpose of such practice. What is doctor trying to check with this?

Really curious

Not surprising if some of the doctors did a part of the breast examination in this fashion. It's only a way to feel any small lumps that may be lying deep in the breast tissue and may be missed otherwise. Women are asked to keep their hand behind the back of their head for the very same reason. One method brings forth an underlying lump/mass while the other just pulls back the excess soft tissue that may hamper the examination.

Thanks for the explanation @Drpseudo

I didn't know if this was actually a practice

Depends on the provider, I have a Dr who palpates supine and nothing else. Then there is a NP who does all the positions as you would see on an educationAl video.

Yes. With hands pressed into hips.
