Actor Shaun Dooley said: “So sorry mate to see what you're going through. Keep strong Sarah, keep fighting and kick its arse!! Thinking of you and your family.”
While TV presenter Kirsty Gallacher said: “So much love sarah.”
Her presenter pal Victoria Derbyshire, who also battled breast cancer after being diagnosed with it in 2015, commented: “Hi Sarah I just wanted to send loads and loads of love and strength to you and all your boys/men.”
Beeny has four sons, Billy, 18, Charlie, 16, Rafferty, 14, and Laurie, 12, with her husband of 19 years, Graham Swift.
Beeny, who is best known for her work on UK property programmes, including Help! My House Is Falling Down and Sarah Beeny’s New Life in the Country, admitted, during an interview with the Telegraph earlier this week, that she had “a little bit of a breakdown” after receiving the news in a hospital consultation room.
Speaking to the newspaper, she said she began a course of chemotherapy to treat the cancer last week and will have surgery and undergo radiotherapy in the new year.
Despite her diagnosis, Beeny, who lost her own mother, Ann, to the disease 40 years ago when she was 10, has said she will continue to work. She is focused on a new Channel 4 series and book she has planned for later in the year.
Beeny also said: “I’m lucky because I live in a family where we all talk.”
She added that she plans to draw on her “inner strength” throughout her treatment process.
