Gynaecomastia or breast tissue

Because of the testicular failure, the testicles may be stimulated to make more oestrogen than that seen in an XY  male. This may  give rise to an increase in breast tissue or gynaecomastia. This can sometimes be exacerbated by testosterone replacement therapy (TRT) as testosterone  can often also be transformed into oestrogen.

Are KS adults more vulnerable to lumps or breast cancer?
+

Although there is an increased  risk of breast cancer, it appears to be about  70% lower than for females.  XY/XXY mosaics may have a slightly higher risk than non-mosaics.

It is recommended that all KS adults should self-examine regularly.

Does the NHS view breast tissue removal as just cosmetic surgery?
+

Where there is excessive breast tissue which is causing distress, it may be funded by the NHS. However, this will depends on individual consultants, the area of the country and the individual’s overall health.

A plastic surgeon with previous experience  should be used rather than a general surgeon.

Can overdeveloped breast tissue be removed by liposuction?
+

In some situations a small incision can be made just beneath the breast and the excess tissue removed by liposuction. This can be carried out as a day procedure. However this may not always be suitable.

We have been told by a plastic surgeon that surgery would leave a great deal of scarring, what can we do now?
+

If liposuction is not possible, then a small incision is made just below the nipple and the excess tissue is removed. This will  leave a small scar which should be unobtrusive.

This should be discussed with your surgeon so that you know what to expect.

If the removal of breast tissue is carried out too early, could there be any further breast development later?
+

As long as the surgeon is careful to remove all breast tissue, there should not be any re-growth of breast tissue at a later stage. However, it is important that any treatment with testosterone is then carefully monitored, to avoid excess levels which could again be transformed to oestrogen.
