A cancer victim from Wiltshire who was told she would never fall pregnant is facing a desperate fight for life after putting her chemotherapy on hold – to have her miracle baby.

Kate Coles, 30, was forced to make an agonising choice between life-saving treatment or carrying the child that doctors said would never come.

Experts feared the intense chemotherapy sessions would harm or kill the foetus and advised her to terminate the pregnancy to save herself.

But selfless Kate, from Trowbridge, Wiltshire, chose to suspend the therapy to ensure the baby was safe.

Kate, who was diagnosed with cancer after returning from her honeymoon in 2007, gave birth this month to Izabelle nine weeks early by planned caesarean section. She weighed 3lb 3oz.

But the suspended chemotherapy has allowed Kate's rare form of bone cancer to spread and her life is now hanging in the balance.

Speaking from her hospital bed, Kate vowed to fight the cancer for as long as possible so she can raise her baby.

She said: "When the doctors told us I was pregnant, I was overwhelmed – it was the best news in the world.

"But then they said I needed to make a choice between whether I was going to stay pregnant or whether I wanted to treat the cancer.

"I told them 'She is a miracle baby, there is no choice to make'.

"She is amazing – the most beautiful little princess ever. She's my miracle baby." Kate was diagnosed with osteosarcoma in her left jaw bone just weeks after her marriage to husband Matthew, 34, in August 2007.

Kate then began six months of chemotherapy to kill any malignant cells or prevent them spreading to other parts of her body.

Doctors said the treatment she received was so intense that it would make her infertile.

But the couple were so desperate to have a family they chose to begin fertility treatment and doctors were stunned when Kate fell pregnant just weeks later. But their joy was short-lived after another cancerous lump was found in her jaw.

She was given the choice of having the cancer treated and losing the baby, or giving birth and risking her own. She had one chemotherapy session, but chose to postpone the rest of the therapy until after the birth to safeguard the child.

Her brave actions meant baby Izabelle was born fit and well at St Michael's Hospital at 10.55am on Wednesday, February 18.

But since Izabelle's birth, tests have shown that Kate's cancer has spread to two other places and she is now battling for her life. She said her illness is "horrendous" but added: "I'm such a fighter, I won't let it beat me."

Izabelle is now in an incubator at the hospital, where she will spend the next eight weeks.

Engineer Matt, who works for Wessex Water said they have received "constant support" from Kate's parents Shirley and John Martin, who live near the family home in Trowbridge.

Matt said Izabelle will be christened in the hospital chapel on Saturday.
