The 30-year-old singer has revealed she has spent the past six months recovering from laparoscopic surgery - a procedure that allows a surgeon to access the inside of the abdomen and pelvis without having to make large incisions in the skin - to free her body of the benign growths, which she compared to having a "fruit bowl of pain" inside her "every day" and being six months pregnant.
The 'Video Girl' hitmaker - who split from fiancé Robert Pattinson last year - shared her health battle by posting a video of herself practicing her pole dancing, showing off her post-surgery figure on Instagram, adding: "I am a very private person as u all know and I have gone back and forth in my mind whether to share that this year I have been recovering from laparoscopic surgery to remove 6 fibroid tumours from my uterus. the tumours were pretty huge, the size of 2 cooking apples , 3 kiwis and a couple of strawberries. a fruit bowl of pain every day.
"the nurse said that the weight and size was like being 6 months pregnant.... (sic)"
The musician - whose real name is Tahliah Debrett Barnett - admitted her "confidence was knocked" and she feared she'd never get her body back, whilst hailing anyone else with fibroid tumours "amazing warriors".
She continued: "I tried to be brave but it was excruciating at times and to be honest I started to doubt if my body would ever feel the same again.
"I had surgery in December and I was so scared, despite lots of love from friends and family I felt really alone and my confidence as a woman was knocked... (sic)"
Twigs admitted that was the first time she had felt herself again in months and she is now focusing all of energy on work.
She added: "...but... today whilst dancing with Kelly at the choreography house I felt like my strong self again for the first time in a while and it was magical. thank you precious body for healing, thank you for reminding me to be kind to myself, you are a wonderful thing, now go create and be other once again
"I know that a lot of women suffer from fibroid tumours and I just wanted to say after my experience that you are amazing warriors and that you are not alone. you can get through this.
"and with this I let go of the pain... love always twigs (sic)"
