Liz Sullivan, from Ebbw Vale, was awarded the MBE for her services to the charity she co-founded - In the Pink.
"When the letter came, it was a terrific surprise because it just seemed ridiculous to have an honour for something you enjoy doing" she said.
"I think that it'll raise the profile of our charity. The work that the researchers and the doctors are doing is phenomenal. This will help people understand that".
