A young girl is believed to have become the youngest ever diagnosed with breast cancer at the age of seven.
The young patient’s mother first noticed a small lump on her daughter’s chest when she was five-years-old as she bathed her.
Two years later it was confirmed as breast cancer and she later underwent an operation to remove the affected tissue.
The mum, from Chile, said: “While drying her and putting on cream, I noticed a little lump under her nipple.
"The doctor told me that this was not normal and that it would grow if it was left for a long time, but he never told me it would come to this.
“My daughter is now mutilated and that is the pain I have to live with.
"The only thing she mentions to me when I take her to the oncologist is that she doesn't want to be bald.
"Beyond that, she doesn't understand that she has lost her breast."
The family is currently waiting for test results to find out if the tumour had started to metastasise.
If the girl's diagnosis does not improve, the family said they will visit specialists in Barcelona who have experience in treating young cancer patients.
Paediatric haematologist and oncologist Francisco Barriga said: "Most women who are diagnosed with breast cancer are aged between 50 and 60.
"From there, it starts to appear less frequently, and a case of a child under 7 years of age is completely anecdotal."
Felipe Tagle, president of the Chilean Association of Cancer Patients, added many doctors did not want to take the case on because of her age.
Last week it was reported a mum with terminal cancer has created a 'wish list' of things to do before she dies, including seeing her baby boy write his first word.
Danni Day, 34, was told that she'd never be able to have children after going through chemotherapy for breast cancer in 2017 but later fell pregnant with son Bodhi.
The graphic designer from Loddon, Norfolk, has now began making small plans for the next two years and would love to take Bodhi abroad for the first time.
She said: “We were devastated when we found out the cancer had returned. I was so close to hitting my five-year recovery mark.
"We were just completely blown away. Having Bodhi as well changed my perspective on things."
"I want to potty train Bodhi and see him write a word before I go.”
