Genetic testing for cancer is the process of assessing a person’s genetic makeup from the past to find out if he or she is at risk for contracting a particular disease. This is done by looking at the results of various gene tests conducted through DNA analysis. These genetic tests determine if a person’s DNA reveals a history of cancer or not. For cancer detection, various DNA testing methods are used. Two such DNA tests that are used for genetic testing in India are Brca1 and Brca2.
Brca test is a genetic blood test that helps in detecting the presence of abnormal cells in the blood. These abnormal cells, present in the blood, might be the reason for the onset of breast cancer. A positive result from Brca test helps in identifying the possible location of the breast cancer. A series of DNA tests are conducted to identify the possible genes that are related to breast cancer.
Brca test is also used for genetic testing for breast cancer detection in India. In this test, a sample is taken from the breast and placed on a microscope slide. After gathering the sample, it is run through a machine that causes many millions of colors to show up on the slide. These colors represent different DNA molecules that are found in different locations within the breast tissue. Different DNA molecules may result in different locations in the breast tissue, which can help in determining if the sample shows up in the breast cancer database.
Another method that is used for genetic testing for cancer detection in India is the DNA-based test. In this test, genetic material from the patient’s blood is collected after giving a thorough swab on the area that comes into contact with the patient. The material is then analyzed using a specific DNA typing method and if it matches the patient’s genetic makeup, then it is considered positive for cancer detection in Delhi NCR.
DNA testing for cancer detection in Delhi NCR can also be performed on extracted fluids from the patient. This type of fluid requires special processes to extract it, as the process requires high temperatures for differentiating between normal and cancer cells in the extracted fluid. This is one of the most expensive types of cancer detection tests. Therefore, doctors usually order this type of test for patients who may have other complex medical conditions or tumors.
Genetic testing for cancer detection in Delhi NCR is also done using saliva samples, although this process has its disadvantages. Samples from outside the country need to be collected and processed before being sent to the laboratory for analysis. This costs a lot, and costs have been known to be increasing for imported samples. The test results cannot be relied upon without confirmation from the laboratories in the country where the DNA was taken.
