A woman has made more than £250k (AUD 500k) on OnlyFans in the last year thanks to a rare condition - that has caused her breasts to grow six bra cup sizes.

Pamelia J, who didn't wish to reveal her real name, suffers from gigantomastia, a rare condition which causes rapid and excessive breast tissue growth.

Since she was diagnosed in March 2022, her breasts have grown from a J cup bra size - to an O cup in 14 months.

Pamelia, 27, began using OnlyFans in January 2018 before she developed the condition.

At the time, she made an average of £31k (AUD 17k) per year on the subscription-based platform.

Since her breasts grew, Pamelia's OnlyFans earnings have multiplied and she made more than £250k (AUD 500k) in the last year.

Pamelia, who is lives in Melbourne, Australia, said: "Because it's such a unique niche, it's really amplified the amount I make on OnlyFans.

"I made 500,000 AUD the last fiscal year and I made about 17,000 AUD a year before."

In January 2022, Pamelia realised her chest was growing rapidly as she had outgrown her most worn bra and she was suffering from back pain.

Pamelia's GP suggested her issues were due to the heaviness of her breasts and referred her to a surgeon who diagnosed her with the condition.

Gigantomastia is a very rare condition that causes rapid, excessive breast tissue growth - which caused Pamelia to go from a J cup bra size to an O cup in just eight months.

In January 2022, her bust was 100cm, seven months later she had grown to 114cm.

As of today (10/05), Pamelia’s chest measures 139cm - causing her massive physical and mental discomfort.

Pamelia said: "It causes me back pain, shoulder pain and just pain all over."

She also struggles to find clothing to suit her bust as there are limited options for bigger busted women, especially if they don’t want their cleavage on show.

Pamela said: "I have to buy my clothes in plus-size shops and they aren't for people like me.

"There are lots of clothes and styles that I can't wear because they're too revealing and make other people uncomfortable. I get a lot of looks."

Gigantomastia can be caused by a range of factors including hormonal changes, medications, and autoimmune diseases, but Pamelia’s cause is currently unknown.

She also suffers from polycystic ovary syndrome (PCOS) so is undergoing testing to see if the two conditions could be related.

Despite how lucrative her condition has been, Pamelia is planning on getting a breast reduction next year and would like to reduce her size by about half.

There is a chance that her breasts could grow back to their current size after the reduction, but she is looking forward to having some of her discomforts eased.

Pamela said: "The money has definitely been something that has played on my mind but I'm sure that mentally and physically it's the best decision.
