He removed 6kg - just under one stone - of fat to shrink her breasts to a manageable C cup.The amount of fat removed weighs almost twice as much as an average newborn baby, he said.The medical term for giant breasts is gigantomastia, a form of a condition known as hypertrophy of the breast tissue.It is a rare medical condition and is diagnosed where the breasts weigh more than three per cent of the total body weight. The consequences of having large breasts can be devastating, ranging from crippling back pain, neck and arm pain to headaches, friction rash and a curvature of the spine.It can cause stretching of the skin, which can sometimes lead to sores appearing.Over time, the physical strain of the breasts can cause breathing problems.

WHAT IS GIGANTOMASTIA?
Gigantomastia is diagnosed when breast weight exceeds three per cent of a person's body weight.The enlargement can cause muscle pain, and over-stretching of the skin, which can lead to ulceration.The condition usually affects one breast more than the other, causing asymmetry.It is thought the underlying cause of the condition is a heightened sensitivity to female hormones prolactin, oestrogen and progesterone.Embarrassment can deter women from exercising, leaving them prone to health problems linked to obesity, including diabetes and heart disease.A study published in the Journal of Plastic and Reconstructive Surgery in 2012 found that a woman with very large breasts can lose five years off her expected lifespan if she does not have a reduction. The condition can affect both breasts equally, but usually affects one breast more than the other, causing different-sized breasts.In Mrs Lin's case, her right breast was larger than her left.Gigantomastia is thought to be caused by sensitivity to the female hormones prolactin, estrogen and progesterone, or an abnormally elevated level of these hormones in the blood, or both.Breast reduction surgery: What does it entail?
