Bosses at the Kidney Cancer Association invited the former Bond girl and her father Irv to have lunch with the families of two patients who have battled the illness.
Richards agreed to support the organisation as she lost her mum Joni to the disease on 1 December, 2007, and the meet-up proved to be a moving experience for the Love Actually star and her dad.
Taking to her Twitter.com page, Richards writes, "Having lunch... with 2 families (of) kidney cancer survivors. So grateful Kidney Cancer Association put this together for us. My mom passed away four years ago from it... it's really hard.
"Spent the afternoon with two families dealing with kidney cancer. I lost my mom to this disease.. my dad & I were moved by their journey."
