10Blood Tests
Instead of invasive techniques to diagnose cancer like surgical exploration or tissue samples, a doctor would detect abnormal signs of cancer in your blood. In the early stages, many tumors would also shed proteins, especially PSA or prostate-specific antigen, into the blood. A blood test can easily detect these signs. Recent progress has suggested a new approach for early diagnosis of cancer. It involves microvesicles or tiny particles in the blood. Many cells in the body shed microvesicles, but the number released by tumors can be relatively significant. [10]
