The mother thought her womb had fallen out because of her overenthusiastic dancing, however a doctor told her it was more likely because of childbirth.
The Chinese woman went to see a doctor in the city of Xuzhou, China, because she thought a piece of flesh had dropped from her genitals.
Dr Song Hongjuan, supervisor at the Maternal and Child Health Centre, in Xuzhou, told her she had suffered a uterine prolapse.
The Daily Mail reports that the doctor suspected she had given birth to a large baby at a young age and never been treated for her prolapse.
The surgeon told reporters she had operated on the unnamed woman, who thought she had a tumour, and she was making a full recovery.
Dr Song advised other women to pay attention to their bodies and said illnesses such as constipation, allergic rhinitis and chronic coughs could cause damage to their pelvic floor muscles.
She encouraged mums to practice pelvic floor exercises after giving birth.
