Scientists Develop a Test to Detect Cancer 13 Years Before Onset

Experts from leading universities in the U.S. have managed to develop a test that is 100% accurate for the early detection of cancer. How did researchers arrive at this groundbreaking conclusion? We can understand this with a brief explanation: In the chromosomes found in our body, which contain genetic material, there are two ends – called telomeres (in English: Telomere), and their role is to protect the chromosome.

Within the framework of the study, researchers discovered that in a person who is destined to develop cancer, these telomeres (or "protective caps" in Hebrew) begin an early shrinking process. Once they stop shrinking, it's a sign that the malignant cells have taken over the body, or in other words, the person has cancer.

By examining these telomeres early, it will be possible to assess the extent of damage or alternatively the level of risk a person is subject to before the metastases take over their body. According to Prof. Li-Fang Hou from Northwestern University, who leads the research, understanding the change patterns of the 'telomeres' serve as a biological marker for early prediction of the disease. "Although many people may not want to know that they have a chance of developing cancer in the future," says Prof. Hou, "it can help them make lifestyle changes to reduce their risk level of developing the disease," she states.
