Six siblings in Nassau County were all diagnosed a gene mutation that causes breast cancer. Now they are sharing their stories as News 12 marks Breast Cancer Awareness Month.

Marianne Reverberi, was the first of her six siblings to be diagnosed with breast cancer at age 37.

"I didn't have the time to sit back and worry...all I knew was, I had a 4-year-old and a 7-year-old and it was just time to get down to business," she said. "I'm so grateful that I listened to the symptoms of my body, because had I not, it could have very well been a different story."

It turns out her breast cancer went from a personal battle to a family one. Her siblings, four sisters and two brothers, carry the BRCA gene mutation. That mutation increases the risk of breast and ovarian cancers, according to the American Cancer Society.

Nicole Capitelli, one of Marianne's two daughters, also has the gene mutation.

“I wanted to do whatever I possibly could – now I have two little kids at home, I need to be healthy for them and for myself," she told News 12.

Members of Nassau family have had chemotherapy, radiation and surgeries, including breast and ovary removal.

"If removing that part of your body will allow you to live another 40, 50, 60 years – with your family and friends – there’s not even a question,” said Pat Zinke, of Massapequa.

"They're just breasts and you know what? I'm happy with what I have now,” said Peg Gallagher, of Farmingdale. “They probably look better now than they did back then and it can be done."

The family says they are sharing their story in the hopes of raising awareness about breast cancer in women and men and the importance of early detection.
