Breast cancer survivor Norma Gracia now helps others stay active through Stronger Together Cancer Support, the group she founded after her diagnosis.

The American Cancer Society estimates more than 321,000 women will be diagnosed with invasive breast cancer this year.

"So I was in the best shape of my life, 19 time marathoner getting ready to try to qualify for Boston," Gracia said. "I had a double mastectomy, 6 months of chemo, 3 months of radiation."

Gracia said she learned she had stage 2 breast cancer three years ago and did not let it stop her.

"Personally for me, exercise pulled me through my cancer diagnosis. I feel it saved my life and my mental health as well," Gracia said.

Now in remission, Gracia keeps running and helps other women stay active through Stronger Together.

Lisa Cornejo is part of the group and is fighting breast cancer for the second time.

"For me, it was a shock. I thought I was done," Cornejo said.

Cornejo said the second fight has taken a greater toll on her.

"I had lost my hair the first time, but the second time losing it again, it was hard. It took my body through a lot. I lost all my energy, everything, my muscle tissue. Everything was gone," Cornejo said.

Cornejo said exercise helps her find some peace while she runs or works out.

"It gives me peace of mind when I'm out there running or exercising, my mind goes someplace else. I forget about everything. It gives me a calmness, kind of like meditation," Cornejo said.

For Gracia, her breast cancer journey was never something she expected, but says it led her to a new purpose: helping others.

"We want to make sure that you know cancer is not what it used to be, a death sentence. You can fight and you can literally live life with purpose," Gracia said.
