Cancer
Transcript:
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 bloodstream from cancer cells. Known as a liquid biopsy, the test is distinctly different from and far less invasive than a standard biopsy, where a needle must be inserted into a solid tumour to confirm a cancer diagnosis. CancerSEEK can be performed before any abnormality has been observed, and so enables early diagnosis and an increased possibility of a cure. 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. But the test is still some years away from being used in the clinic.
