Macromastia is a medical concept referring to a condition where excessive breast enlargement causes physical and functional problems such as pain, skin issues, and difficulties in daily life. It does not simply mean having large breasts.
There is no nationally standardized, clear numerical criterion for macromastia. Medical evaluation is comprehensive, considering not only breast size but also symptoms and impact on daily life.
While breast changes may occur as growth spurts or pregnancy/lactation-related changes subside, excessive enlargement or sagging that has already developed rarely improves significantly on its own.
