Breast Screening allows specialist doctors to pick up lumps or abnormalities as small as 2mm, before they can be physically felt by women checking their own breasts.
Mrs Quinn said having a mammogram every two years significantly reduced your chance of death, and treatments associated with breast cancer.
"And it also provides reassurance because most women will not have breast cancer."
A surprising factor is that many women who are diagnosed with breast cancer, do not have it in their family history.
"We need to change people's thinking around this," Mrs Quinn said.
"All it takes is doing something relatively quick that can save your life."
For mammograms to be effective, they need to be repeated every two years.
"We have what we call a regular screening programme and this allows us to notice even subtle changes in the breast.
"It is the most reliable way of checking."
BreastScreen Coast to Coast covers a large area, stretching from Gisborne down to Otaki.
Breast cancer is the most common cancer in women, with more than 600 dying each year as a result.
Mammograms are free for those aged 45 to 69 as they are more at risk than their younger counterparts.
The appointment can take up to 30 minutes and patients are welcome to come in a group or with friends.
