Following on the heels of recent revelations that x-ray mammography may be contributing to an epidemic of future radiation-induced breast cancers, in a new article titled, “Radiation Treatment Generates Therapy Resistant Cancer Stem Cells From Aggressive Breast Cancer Cells,” published in the journal Cancer July 1st, 2012, researchers from the Department of Radiation Oncology at the UCLA Jonsson Comprehensive Cancer Center report that radiation treatment actually drives breastcancer cells into greater malignancy.
Two major classes of factors influence the incidence of cancer: hereditary factors and acquired (environmental) factors. Hereditary factors come from our parents and cannot be modified. Environmental factors, which include behavioral choices, are potentially modifiable.
It has been estimated by the World Cancer Research Fund that one-quarter to one-third of the cancers that occur in high-income countries like the US are due to poor nutrition, physical inactivity, and excess weight, and thus could be prevented. Maintaining a healthy body weight, being physically active on a regular basis, and eating a healthy diet are as important as not using tobacco products in reducing cancer risk.
