[:en]Researchers have developed a blood test that can detect the presence of eight common cancers. Called CancerSEEK, the blood test detects tiny amounts of DNA and proteins released into the blood stream from cancer cells. This can then indicate the presence of ovarian, liver, stomach, pancreatic, esophageal, bowel, lung or breast cancers.
Known as a liquid biopsy, the test is distinctly different to a standard biopsy, where a needle is put into a solid tumor to confirm a cancer diagnosis. CancerSEEK, is also far less invasive. It can be performed without even knowing a cancer is present, and therefore allow for early diagnosis and more chance of a cure.
The test has been shown to reliably detect early stage and curable cancers. It has also been found to rarely be positive in people who don’t have cancer. This prevents significant anxiety and further invasive tests for those who don’t need them.
Several cancers can be screened for at once, and the test can be performed at the same time as routine blood tests, such as a cholesterol check.[:]
