The Reason We Don’t Get Heart Cancer As you likely know, we receive half our genes from our mothers, half from our fathers. While it would seem our genetic fate is sealed, “nothing could be further from the truth,” said Gaynor, whose new book on the subject, The Gene Therapy Plan, will be available in 2015. “We understand now how gene expression can be modified throughout your life… and that can create cancer,” he said. In fact, our environment affects which genes become expressed (activated) as well as how frequently they become activated. And carcinogens coming from our food and environment are one of the many factors that influence which genes are activated or not. “A lot of toxins are found in breast tissue, because there are a lot of fat cells there,” Gaynor explained. “And toxins are found wherever there is the most fat.”
While our bodies have some defenses against these contaminants, in the form of detoxifying enzymes, and while our bodies are supported by micronutrients which turn on tumor suppressor genes, dangerous toxins found in our fat tissue still modify our genes, which can result in cancers forming in the organs of our bodies, especially those containing fatty tissue.
This, then, is why the heart is so exceptional: “There’s not a lot of fatty tissue [in the heart],” Gaynor said. Even more, “the heart’s enclosed in a membrane,” he explained. Known as the pericardium, this fluid-filled sac may itself become engulfed by cancer, with tumors metastasizing to the outside of it, but still it does its job of protecting our precious hearts. So, even though cancer can happen anywhere there are cells, your heart remains virtually immune due to its muscular nature and the assistance of the pericardium. Smart heart.
