Detecting cancer with a simple blood draw could soon be a reality

Every year, thousands of Americans undergo routine screening for detecting cancer in its early stages, while it’s still treatable. But those routine checks may be painful and invasive, and medical doctors only regularly screen for five of a number of the most common types of cancer. So for decades, scientists had been running on methods that can help in detecting cancer using an easy blood draw instead of a painful biopsy or invasive check. These so-called “blood biopsy” tests are nearer than ever to dramatically enhance the manner medical doctors screen for cancer.

Galleri, a new blood test by health care company GRAIL, is one of the most advanced blood biopsy tests. It works with the aid of using seeking out fragments of DNA in a person’s blood that suggest the presence of greater than 50 types of cancer. According to Dr. Pashtoon Kasi, director of colon cancer studies and precision medicinal drug at Weill Cornell Medicine, the underlying technology changed into sincerely first used to serve a different purpose. “The equal era has been around for more than 20 years,” he said. “It began out with prenatal diagnostics.” But now, similar technology has been harnessed to locate early signatures of cancer. Dr. Michael Seiden, the previous president of the US Oncology Network, sees blood biopsy checks as a part of the destiny wave of so-referred to as “precision medicine” — the concept that every person’s hospital therapy may be tailor-made to match their precise genetics, scientific desires, and particular characteristics. Precision medicine tries “to learn as much [as possible] about a person’s health through sort of sophisticated diagnostic tests,” Seiden said. According to Kasi, much less than thirds of Americans get screened for colon cancer, which regularly entails an invasive system referred to as a colonoscopy. A simple blood biopsy including Galleri can also additionally enhance contemporary cancer screening because of ease of use, he said.

But in spite of the current advancements, many medical doctors say there’s an extended way to go — and a few say there are motives to anticipate greater research to be done. The Galleri check, though promising, is not yet FDA approved. It still needs to go through greater testing to expose it is able to produce dependable results each time.
