How much is it for tummy tuck and 2 rib removal in London, GB?

Costs can vary depending upon the area you live in. I would recommend you call several doctors to get quotes. I would not recommend rib removal, there is very little to gain and it carries too much risk.

Every surgeon's office is going to vary by Price and expertise.  I would caution that rib removal is an extreme surgery that I myself do not recommend.  Not many plastic surgeons perform it, so if you do proceed with this, make certain above all else that your surgeon is well experienced with high volume in this, regardless of the Price they chargeBest of luck!
