A 25-year-old woman from Scotland has described how a rare medical condition has left her with size O breasts that continue to grow, causing chronic pain, financial strain and intense public scrutiny.
Summer, who has built an online following as an adult content creator, has been diagnosed with macromastia, also known as gigantomastia or breast hypertrophy. The condition causes excessive and often rapid breast growth that is benign but can be physically disabling.
She said she first noticed that something was different about her body in childhood. According to her account, she was already wearing a B-cup bra by the age of 10. By 16, her breasts had grown to a double J cup, a size that made it difficult to find standard underwear and pushed her towards corsets and made-to-measure bras.
At the same time, she recalled facing harassment and unwanted attention in public, with strangers commenting on or staring at her chest. She said that despite the visible and rapid growth, her concerns were initially dismissed by doctors, and she struggled for years to obtain a clear diagnosis or treatment plan.
Macromastia is a rare condition, with medical literature recording only a few hundred documented cases worldwide. It can arise spontaneously or be linked to life stages such as puberty and pregnancy, or to certain medications. In many cases the cause is classed as idiopathic, meaning no clear trigger can be identified.
For Summer, the growth has been gradual but relentless. She said her bust increases a little every month, sometimes by more than one cup size. Doctors now estimate that her breasts weigh around 25 kilograms in total, placing significant strain on her back, shoulders and posture and affecting almost every aspect of her daily life.
The physical impact includes constant pain, difficulty standing or walking for long periods and challenges in sleeping. Medical guidance on gigantomastia notes that patients commonly report neck and back pain, shoulder grooves from bra straps, skin irritation or infections beneath the breasts and problems with balance and mobility.
Summer said the size of her chest has also dictated what she can wear. Standard clothing rarely fits, and she has to consider the weight and movement of her breasts whenever she buys an outfit. She has described feeling self-conscious when clothes ride up or fail to provide adequate support, and said simple activities such as walking down the street or shopping can become uncomfortable because of both physical strain and public reactions.
One of the most immediate financial burdens has been underwear. Because of her measurements, she cannot buy bras off the rack and instead relies on custom-made garments. She said she has spent hundreds of pounds on individual bras and recently paid £800 for a bespoke item from a local shop, only for it to break after about a month of use. “It funnily enough broke in a month like they all do,” she told the Daily Mail, describing the strain placed on the stitching by the weight of her chest.
Even when the bras hold, they rarely provide lasting comfort. She has spoken about straps digging into her shoulders and underwires cutting into her skin, leaving marks and sometimes broken skin. Those experiences are consistent with what doctors describe in medical literature on macromastia, where the excess tissue can cause chronic skin problems and lesions as well as musculoskeletal pain.
Summer said she has repeatedly sought a breast reduction since her mid-teens. She first raised the possibility of surgery around the age of 16, when the size and weight of her breasts began to cause daily pain. However, she said requests were turned down multiple times, with clinicians either downplaying her symptoms or suggesting she wait to see whether the growth would stabilise.
Breast reduction surgery, known medically as reduction mammoplasty, is considered the most common treatment for macromastia when conservative measures such as pain relief and supportive garments fail. Surgeons remove excess breast tissue and skin and reposition the nipple to create a smaller, more proportional breast. Health services generally assess candidates based on physical symptoms, body weight, overall health and, in some systems, strict funding criteria.
Because macromastia is benign, it is not cancerous and does not spread. But specialists warn that if left untreated, the condition can lead to significant disability, including long-term back problems, recurrent infections and severe psychological distress linked to body image and social isolation.
Summer has spoken about the mental toll of living with a body that attracts constant comment. She said she was teased at school and later catcalled in public spaces, and that some people reduce her to her chest size without acknowledging the underlying medical issue. Social media, where she now works as a content creator, has brought both support and further scrutiny. While some followers offer encouragement and empathy, others post sexualised or mocking remarks about her appearance.
That online presence is also a practical decision. Summer has said that traditional employment can be difficult because of pain, fatigue and the need for frequent medical appointments. Income from her digital platforms and adult content helps cover living costs and the considerable expenses of specialist bras and clothing. The visibility has also allowed her to talk directly about macromastia, raising awareness of a condition that many people have never heard of.
In interviews, she has described a gradual shift in how she views her body. She acknowledged that for years she assumed the growth was simply “normal growing” and compared herself only to other girls in her peer group. It was only when she realised that her friends’ development had stopped years earlier while hers continued that she understood something more serious was happening, leading eventually to diagnosis.
Even with a diagnosis, she remains in a difficult position. The weight of her breasts means she cannot easily take part in exercise or high-impact activities that might otherwise help her general health. She must plan journeys around the availability of seating and avoid situations where jostling or sudden movements could cause pain. Everyday tasks, such as bending to pick something up or carrying shopping bags, are shaped by a constant awareness of her chest.
Medical experts say that because macromastia is so rare, there is no universal standard for when surgery is offered. Some clinicians define the condition based on the weight of tissue that would need to be removed, while others focus on the severity of symptoms such as pain, recurrent infection or documented mental health impact. Case reports show that in some women the condition stabilises on its own, while in others it progresses until surgical intervention is the only realistic relief.
Summer has spoken about still wanting a reduction operation, both to ease pain and to give her more freedom in daily life. At the same time, she has tried to maintain a sense of humour and resilience. She has joked about having “ever-growing” breasts and said her aim is simply to feel comfortable in her clothes and in her body, even as the condition continues to evolve.
For now, she continues to live with macromastia, balancing medical appointments, online work and the practical challenges of a chest estimated to weigh as much as a small suitcase. Her story has resonated with many people online, particularly women who have experienced difficulties accessing breast reduction surgery or who live with other chronic conditions that may be invisible until they become impossible to ignore.
Her experience also highlights a broader debate within health systems about how to classify and treat conditions that are technically benign but life-altering. For patients like Summer, the question is not cosmetic but functional: whether they will be able to work, move freely and live without constant pain. As she continues to publicly document her condition, her account adds a personal dimension to a medical diagnosis that, while rare, carries profound consequences for those affected.
