The former English teacher had the primary cancer in her ascending colon and a 15cm tumour in her left liver.

Diagnosed at A&E, she was told she had three months to live and palliative care was all that was offered.

Chemotherapy did not work and research led the family to discover the biological drugs, Avastin and Cetuximab, being used in Europe and America.

However, the drugs were not available on the NHS so the Moss family

paid £21,000 for the drug, dramatically shrinking the tumour in her liver so that it became operable. The colon and the left liver were removed in one operation by two separate teams of surgeons.

Infections followed and she had an adjuvant treatment but as soon as this treatment stopped, the cancer returned all over the lymph.

She said: “I was given six treatments of basic chemotherapy that had failed me before and something that seems like a miracle took place. The cancer disappeared. It was now September 2008 and it has never returned since then.

“Now you may still be asking why I feel guilty. It’s because I had the worst prognosis, yet all the people with whom I made friends through cancer, and who had a much better prognosis than me, are now dead. Why didn’t I die?

“This guilt has led me to try to help others and both Mark, my husband, and I have continued with our advocacy, trying to make conditions better for other patients in the UK and in Europe.

“You can imagine the excitement I felt when I heard about Continuum Life Sciences and the work pioneered by Dr Hull.”

Mrs Moss added: “I don’t ever forget what it would have been like for my family if I had died. Our two sons would not have had a mother; my husband would not have had a wife. That night when I had been told that I only had three months, I wrote letters to each of them telling them that I would be there in spirit when they graduated, got married, started their first jobs and I would be feeling very proud of them.”
