Lung cancer, brain tumors, skin cancer and leukemia are known and common. Each member of the body can develop cancer cells in which it attacks its healthy tissue, but there is one member with whom cancer does not seem to mix, and most people have not heard of it. However, "heart cancer" is a real disease that exists, although far less than others, according to a report published on the "Readers Digest" website, which spoke to specialists about it.
"This type of cancer affects 50 million people," said Dr. Salim Hayek, a cardiologist at the Franklin Heart and Vascular Center at the University of Michigan, a specialist in heart tumors.
To understand why the rarity of heart cancer, it is important to know how cancer develops and spreads. Cell growth and normal division can result in altered cells or mutations due to genetic or environmental factors. These cells begin to grow rapidly and divide, ignoring the signals, said Steve Zaidas, head of heart surgery at Columbia University's Mount Sinai Medical Center. Designed to direct her to death. In the end, this leads to a cancerous tumor.
"Ironically, the factors that lead to heart disease are the same that make the heart less prone to cancer.Most of the muscle cells in the heart are unable to divide and grow numerically.These cells are organized and engaged in mechanisms that do not allow them to regenerate.In the absence of rapid rejuvenation, it is difficult for the heart to repair the damage, but that means that the ability of mutations to become cancer is very limited. "
At the same time, says Zaidas, the heart is better protected from environmental risk factors than the rest of the body: "The heart is much more vulnerable than the rest of the organs to exposure to external carcinogens and no contact with some of them, such as when inhaling the lungs, so there are some factors that can cause heart cancer, but some cases, such as Carney's syndrome, increase the risk.
