For me it wasn't a problem being accepted by the NHS. It seems that the NHS practices different rules in different areas or maybe it just depends on which doctor you see. I've heard others talk about decisions being made by a panel, but that never happened in my case.
Initially I went to see my GP and showed him my gyne, which I was told was unilateral (one sided) that could mean I may not get it on the NHS, since it wasn't affecting both sides. He set up an appointment with an NHS cosmetic surgeon, who I went to see about a month later. The surgeon had a look then sent me to another area to have ultrasound done. I then returned to see the surgeon with the ultrasound image. He then told me that they could offer me surgery on the NHS and proceded to explain the procedure and issues. However, although I was happy to be offered the Op, it was clear that this surgeon didn't have much experience in treating gyne (he only does a few gyne ops a year) and told me there will be visible scarring, he's not gonna get rid of it all, just reduce it and in the end my chest will still be uneven. This was enough to make me reject his offer.
I can remember seeing seeing a documentary and reading on here about bad NHS experiences and I didn't want to have a bad result. At the end of the day when you take your shirt off, you don't want people noticing that you still have a small man-boob or big scars on the chest, that they will be curious about how you got them. So I decided to go private because although I'm not the type to go for cosmetic surgery, I really needed to have it done by someone who knows what they're doing and had a good track record. So I went with Karidis to have it done and am quite happy with my decision.
