A young woman from Scotland says her breasts have continued to grow because of a rare medical condition that causes rapid enlargement of breast tissue. Summer Robert, 25, is only 4ft 9in tall, yet her chest now weighs more than four stone. Doctors have diagnosed her with macromastia, and they believe she may also have gigantomastia, a condition in which breast growth continues over time without slowing.

Summer says her chest began to develop unusually early. She was wearing B-cup bras at 10, and by 16 she had reached a double J. As an adult, her bra size now changes often, and in the past year she says she has gone up 10 sizes. The constant weight has caused severe back pain, and she relies on corsets and custom bras, some costing hundreds of pounds.

She explains that doctors once dismissed the sudden growth as normal puberty, and later told her to lose weight, even though she was slim. Being repeatedly told she was “too big” at a young age affected her deeply, and she says it contributed to an eating disorder in her teens. Her family helped her recover, but the struggle stayed with her.

Although one doctor agreed she needed reduction surgery, the procedure was denied because her BMI exceeded NHS guidelines. The decision left her without options for relief.

Summer has also faced years of unwanted attention and discomfort in public. Recently, she has tried to rebuild her confidence by creating online content, which she says has helped her view her body with more acceptance while she continues to seek medical support.
