The researchers at John Hopkins University have conducted a study that held ‘bad luck’ responsible for many common cancers.
Detailing about the study, researcher Bert Vogelstein, said, “The findings suggested that all cancers are caused by a combination of bad luck, the heredity and environment, and we have developed a model that may help quantify how much of these three factors contribute to cancer development.”
Vogelstein, M.D., is a Clayton Professor of Oncology at the Johns Hopkins University School of Medicine.According to the researchers, the cells often commit minor errors while copy themselves.
These errors are often harmless and can even end up causing cancerous cells, the researchers found. They also found that the stem cells that take on these errors can develop into many types of cells, which raises the chances of growing into cancer cells. The scientists said more mistakes up the risk of cancer.
According to the researchers, two-thirds of “adult cancer incidence across tissues” can be easily understood by such kinds of cell division errors.
Vogelstein said, “Cancer-free longevity in people exposed to cancer-causing agents, such as tobacco, is often attributed to their ‘good genes,’ but the truth is that most of them simply had good luck.”
As neither the habits nor the genes can always predict the possibility of cancer, the only method to stay safe is early detection, the researchers noted.
The study’s findings were published in the journal Science.
