A mother-of-four says she has been de-friended by more than 100 people after she posted pictures of her cancer surgery scars on the website.
Beth Whaanga wanted to highlight the need for regular self checks by publishing pictures of the results of a double mastectomy, breast reconstruction and a hysterectomy.
Her sister Emma Rayner, defended Mrs Whaanga who was diagnosed with breast cancer on her 32nd birthday last year.
Ms Rayner said: “What gutless people. People have tried to get it off Facebook. In no way is this picture pornographic.
“It represents the truth about cancer and what measures some women will need to take to survive. I think it’s brave that she can show her scars and I think many more women will hopefully check their own bodies every now and then.”
Mrs Whaanga, from Brisbane, Australia, has had contact with Facebook which has said it won’t pull the images, which were taken for a campaign called Under the Red Dress.
She said: “Cancer effects people in many ways and its important that those of us who can set the example do.”
Speaking about her reasons for having the pictures taken, Mrs Whaanga said: “The aim of the photo shoot was to make women and men aware. Aware of any changes to their body, to show that cancer does not discriminate between gender, race, or age.
“It effects all of us. For those of us who have been lucky enough to prevent their condition from continuing or occurring we have a responsibility to make others aware.
“Check your breasts/pectorals under your arms and neck. If you find anything don’t brush it off, better to be safe and alive.
The pictures were taken by photographer Nadia Masot, a friend of Mrs Whaanga, and put online on Sunday.
