TODAY, we're asking you to help in the battle to save the life of a 17-year-old girl battling cancer.

Emily Clark, from Cwmbran, needs a bone marrow transplant after she was last week dealt the terrible news that her cancer, Non Hodgkin Lymphoma, had returned.

On her blog she writes she was “devastated” with the diagnosis after having got her life back on track and making an application to university, which she has now withdraw.

But Emily, from Llantarnam, who has campaigned tirelessly for people to sign up as bone marrow (stem cell) donors and set up a charity for sufferers of Non-Hodgkin (Burkitts) Lymphoma, now needs the transplant herself.

She is currently receiving chemotherapy treatment at the Teenage Cancer Trust at the University Hospital of Wales, and this hasn’t stopped the Croesyceiliog Comprehensive pupil campaigning from her bed on her web page Remission Possible.

Now, Emily needs us to return the favour - and the Argus is getting behind her search for the donor who could save her life.

We want our readers to join the bone marrow register to show their support, in the hope one of them will be a match for Emily. All you have to do initially is join online, then provide a saliva sample by post.

To help Emily, if you are aged between 16 and 30 you can join the Anthony Nolan bone marrow register, and if you sign up, please tick Emily’s campaign 'Remission Possible' as a reason for joining. If you are aged between 17 and 55, you can join the Delete Blood Cancer bone marrow register.

You can read Emily's campaign blog here.

We're also backing Emily's plan to get #RemissionPossible trending on Twitter today. If you register as a donor, tweet that to @RemissionPos using the hashtag.

She said: “My transplant donation will come from someone selfless. My 15 year old sister will be tested to see if she is a match for me, but this is only a 25% chance. The likelihood is that I will have cells donated from an unrelated donor, a stranger. A hero.”

Her mum, Donna Dunn added that the race is now on to find a bone marrow donor match for her daughter by February.

Emily is urging potential bone marrow (stem cell) donors to sign up to the register to increase the chances of there being a match for her or the other 1,800 people who will need a transplant this year in the UK.

She added: “The thing is, it’s not just someone needing you to become a lifesaver. Now, it’s me- Emily Clark... the girl who aspires to be a doctor and loves to sing.

“I hope an emotion within you, whether it be sorrow because of my cancer returning, empathy and pity for ‘that’ girl with cancer, or admiration incites a want to sign up.”

“Do it for me, do it for the other 1,800 people”, she added.

Earlier this year, she inspired Newport Mayor, Cllr Matthew Evans to choose Teenage Cancer Trust as one of the charities supported by the mayor’s fund this year.

He described her as “inspirational” adding “she works hard to raise awareness of cancer amongst teenagers and I wish her every success with the campaign.

“It is important for people to listen to her story and to sign up to the bone marrow register.”

In November 2013, Miss Clark noticed her stomach swelling and her jeans becoming tight, and scans at The Royal Gwent Hospital revealed she had Non Hodgkin (Burkitts) Lymphoma, on December 20 last year.

Following four courses of chemotherapy she was given the news she was clear of cancer on April 17.

While in remission she began supporting others by launching the campaign Remission Possible and encouraging the public to join the bone marrow register- something that Miss Clark requires herself following her relapse on November 17.

The Head of Register Development at Anthony Nolan, the UK's blood cancer charity, Ann O’Leary, said: “Emily has been a great and selfless supporter of Anthony Nolan even before she needed a transplant by supporting other families in desperate need online. Emily is now reliant upon other selfless strangers to join the register and pledge to save a life by donating their stem cells.

“What many people don’t realise is how easy it is to join the bone marrow register – it simply involves filling in a form and providing a saliva sample."
