Cell Neighborhoods Can Help Prevent Breast Cancer

The exercise gave Lu-Ann Doria more energy, strength and confidence. It can also help you free of cancer, say doctors.

Doria, 57, to his work for the first time three years ago, after recovering from a breast cancer therapy. At first she was so tired he had held a nap before the dance class.

Well, Doria exercises five days a week. Search step, a dance class called Zumba, to lift weights themselves.

"I feel I can do things first, I was talking about things," said Doria, in Rye, New York, works with a personal trainer at the YMCA through a joint program with Livestrong for the survivors of cancer.

And even with rheumatoid arthritis, Doria said, "I sleep better, I do not feel stressed two weeks ago, I went to my rheumatologist want, and let my medication he said :..." I do not feel inflammation in the body. Keep doing what you do. "

Researchers have known for years that people who are active and finishes are less likely to develop cancer. And survivors, and the pursuit of maintaining a healthy weight are less likely to relapse.

Only recently, however, scientists began to unravel, how to be active helps ward off cancer.

The surrounding tissue, blood vessels and cells of the immune system - - Although the exercise can not change the inner workings of a cancer cell, physical activity can modify the vicinity of the cell, such as the famous "microenvironment," Patricia says Ganz, breast cancer specialist at UCLA Jonsson Comprehensive Cancer Center.

"This is a new frontier in cancer research," says Pamela Goodwin, a professor of medicine at Mount Sinai Hospital, University of Toronto.

Healthy neighborhoods are important to cells because they are children, says William Li, president of Boston-based Foundation angiogenesis, the promotion of research on cancer and other diseases.

It compares a cancer cell to a single "bad boy" living in a good neighborhood. Even a young offenders who do not seek to be able to cause many problems when it is surrounded by attentive parents, neighbors and local police. Exercise helps to improve the neighborhood, keep the cancer under control, Li said. Lack of exercise - and with a lot of weight - the damage of the district, making it easier for cancer to ravage.

In particular, exercise helps prevent chronic inflammation, a process that can fuel cancer, the change in the environment of a tumor cell. Exercise helps lower insulin levels and sex hormones such as estrogen, that can release growth factors to survive and spread of cancer cells, Li said. And learned how, Doria, exercise also helps mental stress, which can also reduce inflammation, said Ganz.
