CLEVELAND -- If you knew how to prevent breast cancer, everyone would most likely do it.

In this week's Loving Partners story, NewsChannel5's Alicia Booth reported on one way you might be able to prevent it.

Barb Inderlied is taking the only steps she knows to fight breast cancer.

She's heard that nearly 30 studies have shown that women who exercise at moderate to vigorous levels for three or more hours per week can reduce their risk of getting breast cancer by 30 to 40 percent.

"Oh, I believe in it, and that's why I teach a class twice a week," she said.

And in a sense, Inderlied is running from cancer.

"I'm the only one in my family (who) is cancer-free at the moment," she said.

Fifteen years ago, everyone in her family was healthy. Since then, her mother died of ovarian cancer, colon cancer took her father's life, and perotid gland cancer killed her older brother. Another brother continues to battle skin cancer, and her younger sister is fighting breast cancer.

"I can choose two things," she said. "I can think about it and become depressed, or I can live every moment of my life."

Dr. Paula Silverman of University Hospitals spends much of her life treating cancer, and she said that exercise certainly can't hurt.

"Women in studies where they do regulate exercise do have a lower incidence of breast cancer than women who don't exercise," Silverman said.

One group of women does a lot more than exercise together; it is truly what the concept of Loving Partners is all about, NewsChannel5 reported.

"We all keep track of how we're feeling, what we're doing and we've all been very healthy," Inderlied said.

Whether cancer is in your family or not, exercise does wonders for your heart, it strengthens your bones, it can make you sleep better, and it can keep your weight down, according to doctors.

NewsChannel5 is urging you to find the time to get a loving partner -- like a sister, a mother, or a friend -- and remind her to do a breast self-exam once a month, on the fifth day after your cycle.
