Gynaecomastia is usually graded from 1 to 3 according to how large the breast tissue is and whether there is excess skin. Grade 1 is a small enlargement without extra skin, grade 2 is moderate enlargement (2a without and 2b with some excess skin), and grade 3 is marked enlargement with loose, overhanging skin. The grade helps a surgeon decide between liposuction, gland removal and skin reduction.
Why surgeons grade gynaecomastia
Grading is a shorthand for describing how much tissue there is and how the skin is behaving. It is not a measure of how much the condition matters to you: a small grade 1 puffiness under the nipple can be just as distressing as a larger chest. The main value of grading is practical. It predicts whether the skin is likely to shrink back after tissue is removed, which in turn tells the surgeon whether incisions can be kept small or whether skin needs to be cut away.
The commonly used grades
Several classifications exist. One of the most widely used, the Simon classification, describes the following:
- Grade 1: a small, visible enlargement, often a firm button of tissue under the areola, with no excess skin.
- Grade 2a: moderate enlargement spreading beyond the areola, with no excess skin.
- Grade 2b: moderate enlargement with a small amount of excess skin, so the fold under the chest may start to show.
- Grade 3: marked enlargement with significant excess skin, giving a hanging, more female-looking breast shape, and the nipple often sits lower.
Other systems also consider whether the tissue is mainly gland or fat, and how low the nipple sits relative to the fold beneath the chest.
Gland, fat or both
The grade describes size and skin, but the type of tissue matters too. True gynaecomastia is glandular tissue, which feels firm or rubbery and sits directly behind the nipple. Pseudogynaecomastia is fullness made mostly of fat, which feels soft and is often linked to weight. Most men have a mixture. Firm glandular tissue does not respond well to liposuction alone, so it usually needs to be removed directly, whereas fatty fullness often responds to liposuction.
How the grade affects surgery
- Grade 1 and 2a: usually treated with liposuction and removal of the gland through a small incision on the lower edge of the areola. Scars are short and typically fade well.
- Grade 2b: the same approach often works, as mild skin excess may tighten over several months. Occasionally a small skin reduction around the areola is added.
- Grade 3: skin excision is often required. Depending on the degree of laxity, this may mean a scar around the areola or longer scars across the lower chest, and in some cases repositioning of the nipple.
These are general patterns, and your plan depends on your own examination.
How your grade is assessed
Mr Nassab will examine you standing up and lying down, feel the texture and extent of the tissue, pinch the skin to judge its elasticity, and note the position of the nipple and the chest fold. He will also ask about weight changes, medications, supplements and any steroid use, as these may influence both the cause and the plan. If a lump is hard, fixed, on one side only, or associated with nipple discharge or skin changes, further investigation is arranged before any cosmetic treatment is considered.
Can the grade change?
Yes. Gaining weight can increase the fatty component and move a man into a higher grade, while losing weight may reduce fat but leave the gland unchanged and the skin looser. Large weight loss often results in grade 3 laxity. For this reason, it is best to reach a stable weight before surgery. In teenage boys, pubertal breast swelling often settles, and cosmetic surgery is only offered to adults aged 18 and over.
Frequently Asked Questions
How can someone find out which grade they have?
Only an in-person examination can tell you reliably, because it depends on tissue type and skin elasticity as well as size. Photographs alone can be misleading.
Does a higher grade mean bigger scars?
Often, yes. Grades 1 and 2a can usually be treated through small incisions, whereas grade 3 frequently needs skin removal with longer scars.
Can grade 1 gynaecomastia be treated?
Yes. Even small, firm tissue behind the nipple can be removed through a short incision at the edge of the areola.
Can gynaecomastia be graded from photographs?
Photographs can give a rough idea, but they cannot show how firm the tissue is or how well the skin will recover. That is why grading is confirmed at a face-to-face consultation.
Is the cost linked to the grade?
Gynaecomastia surgery costs from £9,500 and the complexity of surgery affects your final quote. The £150 consultation fee is charged separately.
