Barbara, 50, was diagnosed with breast cancer in 2005, but, because it was not a terminal illness, was told she could not have the treatment.
|"It was a fight to survive. I was passionate about staying alive."|
The Fight of My Life tells of the mother-of-three's struggle to win the right to be prescribed the drug on the NHS, not just for herself but for other women too.
"It's not necessarily a story just about cancer," Barbara told BBC Somerset Sound's Elise Rayner.
"It's a David and Goliath-style story about how you can achieve the unachievable.
"Of course, there are my thoughts and feelings in there about the cancer, which are very near the mark as it was a traumatic time to go through."

Barbara is breast-cancer free for the moment, although the disease could return at any time.
"It was a fight to survive," said Barbara.
"I was passionate about staying alive.
"Putting it all down in this book has been therapeutic, and it's nice to have been able to tell my story."
