The Stony Brook Cancer Center has performed 5,000 mammograms using its Mobile Mammography Van.

The pink and white 40-foot van has been making its rounds across underserved areas on Long Island ensuring that women are being screened for breast cancer.

"The communities we go to, the patients don't have the transportation and we're making it easier for them to come to us because we're coming so much closer to their home," says Patrick Dineen, M.D., program coordinator for Mobile Mammography.

Lida Grajales, of Ronkonkoma, was the van's 5,000th patient. It was her first mammogram.

"It's super easy, it's fast, super simple," Grajales says.

The whole process takes about 15 minutes.

The Stony Brook Cancer Center is anticipating a busy month of screenings in October for Breast Cancer Awareness Month.
