Rare gigantomastia keeps fueling breast growth despite weight loss
Tianna Moon, a 30-year-old from East Anglia, says her 34NN breasts keep growing due to gigantomastia—a rare condition—after shedding weight on the drug Mounjaro; diagnosed in 2025, she struggles to find bras, experiences back and rib pain, and has had a private gastric sleeve to ease pain. Now at 14 stone, she considers reduction surgery while earning around £10,000 a month on OnlyFans, and she faces online skepticism about her diagnosis.
