At 11pm on the day she signed for Real Madrid in February, Linda Caicedo was not out celebrating with family and friends. Instead, the 18-year-old was calling a young cancer patient about to undergo surgery back home in Colombia.

Her journey so far includes a professional and international debut at 14, a cancer diagnosis at 15, and a move to one of the most well-known clubs in the world.

The latest step of that journey came in Brisbane, where she jinked in from the left wing and fired through the gloves of keeper Yoon Young-geul as Colombia beat South Korea in their opening match, to earn only their second ever win at the Women's World Cup.

Caicedo's goal means, at 18 years and 153 days, she is the second-youngest South American player to score a goal in the history of the tournament, with only Brazil icon Marta doing so at a younger age.

Invoking Marta when comparing female footballers is a big statement to make - but Caicedo looks the real deal.

She has been the poster girl for the rise of women's football in Colombia, who only qualified for their first World Cup in 2011 but have been a growing power since.

Born in the town of Candelaria, Caicedo came from a poor background and has never forgotten the sacrifices needed to get her to this point. She recently travelled to Candelaria and donated 100 grocery bags of food to people in need, with no media brought along.

She has a close relationship with the Colombian manager Nelson Abadia, who has been in charge of the national team since 2017 but was involved as technical assistant from three years earlier.

"In 2016 I started with youth divisions, I had Linda here, she was 12 the first time I took her to the national team," said Abadia. "She evolved from there."

'For people with cancer, I am example you can overcome this'

Aged 18, Caicedo has already made 16 senior Colombia appearances, scoring six goals

Caicedo's evolution saw her make her professional debut with Colombian club America de Cali in July 2019, when she was 14. In November 2019, she received her first international call-up.

Yet her meteoric rise was temporarily halted In 2020, when, amid the Covid-19 pandemic, Caicedo began to feel pain in her abdomen.

Following tests, she was informed she had ovarian cancer. Two weeks after the diagnosis, in March 2020, Caicedo had surgery to remove a tumour, which involved the removal of one of her ovaries.

Caicedo has been able to recover from her illness, which she in part puts down to the support from both her family, and her national coach Abadia.

"There was a difficult process, thank God I could overcome it," she said. "My family was always behind me and my coach beside me was always very close.

"He [Abadia] was often calling me. I was going into surgery one day and I felt really bad, like I could not play top level football again; he said relax, you will come back. So I want to thank my coach.

"For people in difficult times like I was, I am an example you can overcome this."

Caicedo started six months of chemotherapy after surgery, and days after finishing treatment - once she was declared cancer-free - she was back at training.

She returned to action with both Deportivo Cali and the national team. While being a senior international, she also continued to gain experience at age group tournaments.

In 2022, Caicedo remarkably played in four separate international competitions - the South American Under-17 Women's Championship, the Under-20 Women's World Cup in Costa Rica, the Under-17 Women's World Cup in India, and the Copa America Femenina.

It was in that latter tournament when the world really started to sit up and take notice of Caicedo. At 17 she was named player of the tournament as hosts Colombia reached the final, where they lost 1-0 to Brazil but had done enough to qualify for the 2023 World Cup.

'I am still young, I still need to learn'

In February 2023, just a few days after Caicedo turned 18, she signed with Real Madrid, becoming one of seven Spanish-based players in Colombia's World Cup squad.

"You need to leave your country to evolve, and support from fans and coaching staff helps me a lot," she said. "This is how I have secured my place at Real Madrid.

"I've played U17, U20, now to be at a World Cup with such experienced players, the experience contributes a lot. I have learned at every stage. I feel this World Cup will be physical, which I will learn with the knowledge already gained.

"I am still very young, I still need to learn lots. I gain experience every day in this team. This is my first senior World Cup, I want to enjoy it. I have a lot of time."

At 18, she is already Colombia's key player - and there was concern during a training session on Thursday when she clutched her chest and collapsed, while on a warm-up jog with team-mates.

She was attended to by medical staff while media at the session were asked to leave, but a source close to the player told BBC Sport she was laughing and joking in the medical room, before being able to re-join training.

Abadia has since confirmed "Linda is fine" ahead of his side's meeting with one of the World Cup favourites, Germany, on Sunday.

Caicedo will hope to continue where she left off against South Korea - a performance described by Colombia assistant Angelo Marsiglia as "extraordinary".

He added: "She wants the ball, never hides, she's from another planet, entirely unique."
