Linda Black, 38, model and TV personality
"My sister-in-law was diagnosed with breast cancer about seven years ago when she was 38 - my current age.
So many questions ran through my mind: Why her? Why so young? Could she have prevented it? I trawled websites, blogs, articles and research papers to find out more about the disease.
The more I read, the more I understood, and my fear of the unknown was lessened.
I also try to share my knowledge with others. I emcee for free at events organised by the Breast Cancer Foundation (BCF), and I try to incorporate useful facts and figures I've come across in my speeches.
I take my hat off to the cancer survivors at the BCF. One who really inspires me is a 40-year old woman whose breast cancer returned after 12 years of remission, and now she's sharing her story to encourage other women around her."
