October marks the beginning of Breast Cancer Awareness Month. There are now more breast cancer survivors in the U.S. than ever, with four million and counting.

It's all about early detection and better treatments aiming to save even more lives.

The American Cancer Society is reminding women to grab your girls. That's about holding friends and family accountable for mammograms. It's a message being shared by two special sisters.

Side by side, these South Jersey sisters have stepped through the ordeal of breast cancer together.

"We know outcomes are so much better when cancers are detected earlier," Karen Knudsen with the American Cancer Society said.

Knudsen said there's still work to do, however.
