We have heard of stomach cancer, lung cancer, liver cancer, and pancreatic cancer, but rarely heart cancer. Why is that?
Cancer is caused by gene mutations, which usually occur during the cell division stage, because at this time the cell replicates its own DNA. If something goes wrong in the replication process, cancer may occur.
Therefore, the more frequently cells divide in a tissue, the greater the chance of cancer occurring in theory.
For example, our liver cells can regenerate quickly after being damaged, skin cells are renewed approximately every 28 days, the taste cells on the tongue can self-renew approximately every 10 days, and the epidermal cells of the colon can be completely replaced within a few days.
The rapid turnover of these cells creates conditions for the accumulation of errors in DNA replication, thereby increasing the risk of cancer.
But the heart is different. It has been given the “cancer-free gold medal” since birth.
Myocardial
Myocardial cells rarely proliferate and divide, and are renewed only about once every 20 years. With this laid-back attitude, fewer mistakes will naturally be made.
Secondly, the heart and blood vessels form a unique closed circulatory system that is not easily invaded or disturbed by foreign harmful substances.
Even if there are foreign cancer cells, the blood flow in the heart is so fast that many mutagenic substances cannot stay, making it like an efficient logistics center.
Coupled with the heart’s special position, it is always in a high-pressure and high-oxidation environment.
This environment will prompt cardiomyocytes to adopt more stringent damage response and repair mechanisms, thereby greatly reducing the possibility of cancer.
Nevertheless, it does not mean that cancer of the heart is completely impossible; cardiac tumors do exist.
According to statistics from the Mayo Clinic in the United States. The center sees an average of only one case of heart cancer each year.
Research shows that heart tumors can originate from cells in the heart itself or from cancer cells elsewhere in the body, and most are benign.
According to clinical data statistics, the incidence of cardiac tumors is only 0.0017%.
So you see, our human body is like a super sophisticate machine. The engine of the machine is not prone to failure.
According to the Creator’s design, except for your brain and eyes. Which will live as long as you, the cells of other organs will be renew at their own pace.
