Detecting cancer is a multi-stage process. Cancer is usually detected by chance while treating the patient for some or the other symptom. Cancer symptoms vary substantially and usually escalate with time. The most types of cancer develop slowly over the years and resemble those of other illnesses or it might even take years before cancer becomes big enough to be detected. Occasional Cancer screening is mandatory to detect the disease at the earliest stage as treatment at preliminary stage has resulted in a high mortality rate.
As there are many types of cancer and symptoms vary in every case, Scientists have developed a universal cancer test that can detect traces of the disease in a patient’s bloodstream. This test is comparatively simple and cheap when compared to numerous series of tests like Magnetic Resonance Imaging, Computed Topography, ultrasound imaging and many more.
Earlier, the researchers look for tiny molecules called methyl groups, which are constantly added and removed to DNA by cellular machinery. Methylation of DNA can be done across the whole genome by doing expensive DNA sequencing to find out exactly how much methylation is present and precisely where, this is the first test to detect if cancer is presently using these methyl nanostructures.
Scientists have found out a much simpler test using gold nanoparticles that instantly change color to determine the presence of malignant nanostructure cells of cancer DNA anywhere in the body in less than ten minutes. Though the test is still under development, it puts light on a radical new approach to cancer detection that could make routine screening for the disease simple and quick. The test has a probability of detecting cancer ninety times out of hundred. This procedure cancer game changer in cancer treatment as early detection can help to provide early diagnosis.
