Can someone explain the oncoblot test that states it can identify 26 types of cancers with a blood test?

Yes. There is a protein that only exists on the surface of these types of cancer cells that the test detects well enough to be the choice in Nat'l Agency research efforts. Here's a clear explanation from a website - there are many. Http://www. Cancercenterforhealing. Com/early-cancer-detection/ Best!
Has tumor marker. The oncoblot test relies on identification of a surface tumor marker, the ENOX2 protein. This is a growth factor protein that appears in a large array of malignancies, not in normal tissue. The 26 tumors that express it are lumped, but not distinguishable as to type. This is similar to mutated mitochondrial DNA present on all tumors and shed in the serum. A good marker is tumor specific.
