(Newswire.net — January 3, 2015) — There are many external factors that can contribute to development of a “bad” cell division in human body, however, scientists agree it is more by sheer statistical chance.
Human body is actually very adaptive. Our cells are dividing all the time, and, with each division, information is genetically copied into new ones in order to protect the organism.
Cancer is nothing more than unsuccessful attempt of a cell to adopt and maintain link with its own functionality and purpose. Those cells then begin uncontrolled multiplication, which eventually cause organism’s dysfunction and death.
Carcinogenic factors such as smoking and sun exposure or hereditary factors contribute to the likelihood of getting the disease, however, a new study from Johns Hopkins Kimmel Cancer Center says most cancers happen simply because that’s the way our bodies are. That explains why some people who smoke or live in unhealthy environment don’t get the disease while others that live healthy, stress-free life, still die of cancer.
A study published Thursday in the Science journal, used a statistical model to compare the lifetime prevalence rates of various cancers with stem cells division rates in 31 types of corresponding tissues. Stem cells are the source of new cells to replace those who die of old age or damage.
The whole concept of healing various diseases with stem cells is to “remind” altered cell which information is original and suitable for sharing. Stem cells actually remind organism of its once-healthy state.
A stronger correlation between the old cells and stem cells suggests that chance of getting cancer depends largely on how quickly stem cells divide. The study showed that the appearance of 22 types of cancers is due to “bad luck” when, instead of stem information, a cell starts to share its altered code.
The research results didn’t show smoking and sunbathing as less dangerous to health, the scientists warned. Lung cancer and skin cancer fall into a third group of cancers, where poor lifestyle habits are a major contribution.
The research, however, is incomplete because it did not include some types of cancer as well as cancers of the prostate, which is the second most common cancer in men. Scientists say they have not been able to find a reliable rate of stem cell division in the scientific literature for those types of tissues.
