The most advanced technology that has been made in the medical field is the ability to extract the DNA from the blood sample and use that sample to analyze the risk of someone developing any disease in the future. This method doesn’t only tell about the probabilities but also enables us to find the preventative methods or medicine against that disease.

For example, it can tell about the higher chances of someone developing breast cancer in the future or any kind of heart disease. If you already know about the possibilities, you can take major steps in advance like changing your lifestyle of taking preventative medicine after consulting a doctor, etc. such an opportunity can give you greater chances of surviving that disease and keep the side effects at a minimum or zero.

It might sound superficial to some people but the reality might surprise you. There are several genetic screening tests that can help you find out about the risk of 10 diseases related to heart or cancer. For example Yale Generations Project. This project screens 10 genes that might cause the risk of a disease that can be prevented. Like BRCA gene mutation. A harmful mutation in this gene can further result in the breast or other types of cancer. The Yale Project studies this gene to look for any kind of mutation in this gene so that can be treated in advance.

Now all these genetic screening tests might’ve given you the impression that it will be a very painful procedure but in reality, it is pretty simple and easy. You can provide the sample for the test by rubbing the inner side of your cheek with a cotton swab. That’s it. It gives the scientist all the samples they require to perform the screening test.
