Chloe Woolfe, now 21, was diagnosed with osteosarcoma in her leg aged 17 just as she was about to start her second year of A-levels.
She was treated at UCLH Hospital in London and her family were supported by a CLIC Sargent Social Worker.
The @NHS Twitter account is curated by a different person every week, and aims to bring to life the stories of staff and patients through their own words.
During the week, from Monday 29 January to Friday 2 February, Chloe plans to talk about her diagnosis, treatment and life after cancer, as well as her support network at different stages of her experience. You can follow Chloe's tweets by following @NHS on Twitter.
World Cancer Day
In the lead up to World Cancer Day on 4 February CLIC Sargent is highlighting the hidden costs of cancer, and the importance of banding together.
Our Hidden Costs report reveals a cancer diagnosis often affects a young person's mental health, not just their physical health. 79% of young people we surveyed felt cancer had a serious impact on their emotional wellbeing , while 70% of young people experienced depression during their cancer treatment.
CLIC Sargent is asking everyone to wear a Band Against Cancer to show support for young lives against cancer for World Cancer Day.
Our wristbands are also available on our website, and from Morrisons stores, J D Wetherspoon pubs and selected H Samuel and Ernest Jones stores.
"I underwent two cycles of chemotherapy before having a distal-femoral knee replacement - a fancy way of saying they replaced my knee with a metal joint and my femur with a plastic piece.
"Following this, I had a further four cycles of chemo, a six month course of immunotherapy, and another total knee replacement where they also removed my knee cap.
"I had to re-train my brain to walk with this new foreign contraption, which was a long, slow and painful process.
"I may never be able to run or wear high heels but here I am today, able to walk using my own leg and my own foot. They say that 10 years ago I would have lost my leg. How lucky am I?!"
Chloe, who lives in Brighton, has recently secured her first full-time job in events, and is passionate about theatre and drama. She also loves travelling and seeing different cultures. Her dream is to eventually live in a Spanish-speaking country to improve her language skills.
She adds: "My aim in life is to enjoy each day and take each one as it comes.
"No-one knows what is around the corner, so it’s really important to me to cherish the little things and not sweat the small stuff."
"Life is too short to be anything but happy."
