The actress, activist and three-year-old mother does her part to change the world.

Jennifer Garner puts her health first.

In honor of Breast Cancer Awareness Month, the 47-year-old actress shared a video on her annual mammogram hour on Instagram, hoping to encourage other women to check themselves out.

"Every October I have a permanent date. For mammograms. For me, appointing books is routine, like a dentist," she writes. "I know it's scary, sisters, but just do it – the next best thing to all is early detection."

The playful video shows Garner looking in the doctor's office during his procedure at Santa Monica's LSG Imaging – doodling the animals on her medical record, blowing out latex gloves and holding on to a frivolous face check.

The health organization added that "only 2 to 4 screening mammograms per 1,000 result in a diagnosis of breast cancer."
