Gynecomastia: Fat, Gland, or Steroids
A chest that looks like breast tissue is three different problems with three different next steps. Why the Brazilian gym word "gineco" is sometimes accurate, and why surgery on fat is the wrong operation.
Brazilian gyms have a word for it — gineco — and they use it for every chest that is not flat. That is how men book liposuction for a gland, wait out a gland that is fat, or ignore a drug they are still taking.
True gynecomastia is glandular breast tissue in a man. Lipomastia (or pseudogynecomastia) is fat. You can have both. A clinician can often tell with two fingers: a firm disc under the nipple is gland; a soft chest that matches the rest of the torso is fat. If the distinction is not obvious, ultrasound is the next step, not a second angle in the mirror.
General educational information, not medical advice. A hard lump that is not centred under the nipple, bloody nipple discharge, or a chest finding in a man who also has a testicular lump is a reason to see someone this week.
The three common Brazilian stories
Puberty. A large share of boys get some glandular swelling. Most of it settles over a year or two. Operating on a seventeen-year-old who has had it for four months is how you operate on something that was leaving.
Age plus a waist. Fat on the chest tracks fat everywhere else. It is the same conversation as belly fat. Losing the pad will not melt a true disc of gland; it will make the disc more obvious, which is useful diagnostically and annoying photographically.
Anabolic steroids. Aromatisation of a testosterone cycle into oestrogen is a classic cause of true gynecomastia in Brazilian academies. It can start during the cycle and it can persist after. Tamoxifen is used, under a specialist, in some of those cases; it is not a locker-room protocol. The wider picture is steroids.
Medicines and other causes worth naming
Spironolactone, some anti-androgens, some ulcer drugs, marijuana in a subset of users, and anything that raises prolactin. Finasteride has reports; they are uncommon at 1 mg. If the chest changed after a new prescription, take the box to the appointment.
Klinefelter and other hypogonadism belong on the list when the testes are small, the arms are long, or the testosterone is actually low. That is when replacement is indicated, not a chest-reduction brochure.
What to do with each
Fat: the waist. Gland that is new, tender and tied to a cycle or a drug: stop the cause, then a specialist. Gland that has been there for years, is fibrous, and bothers you: that is a surgical conversation (subcutaneous mastectomy, often with liposuction of the surrounding fat), not a cream. Creams sold as "gineco" treatments in marketplace listings have the same evidence grade as enlargement pills.
A plastic surgeon who only offers liposuction is offering the wrong operation for a disc. A urologist or endocrinologist is the right first look if the cause is not obviously fat.
