Blood Test Detects Cancer Years Before Diagnosis
Scientists developed a blood test, MCED, that can find cancer early.
It looks for tiny pieces of cancer DNA in the blood.
In a study, the test found cancer in some people up to three years before they were diagnosed.
Researchers used blood samples from a heart disease study.
The test identified colon, lung, breast, and other cancers.
Early detection could lead to better treatment and save lives.
Further studies are needed to confirm the test's effectiveness.
A new blood test, MCED, can detect cancer years before diagnosis.
The test analyzes genetic material shed by tumors in the bloodstream.
Researchers examined blood samples from a study focused on heart disease.
The MCED test detected cancer-linked genetic material years before diagnosis in some patients.
The study detected colon, pancreatic, rectal, lung, breast, and liver cancers.
