Ein einfacher Bluttest kann bei Patienten mit unspezifischen Symptomen wie Müdigkeit, Schmerzen oder Gewichtsverlust helfen, Krebs zu erkennen, und zwar dank einer Proteinsignatur, die mit einer Krebsdiagnose in Verbindung gebracht werden könnte

> Using proteomics, a method for large-scale protein analysis, the levels of 1,463 different proteins in plasma were measured. The researchers identified a specific combination of proteins, known as a protein signature, that could be linked to a cancer diagnosis.
> The researchers then developed a model that can distinguish patients with cancer from those with other conditions, such as inflammatory, autoimmune or infectious diseases, with high precision.
> The researchers emphasise that the method should not replace imaging diagnostics or biopsies, but rather serve as a support for prioritising which patients should be investigated further.

My dad has been diagnosed with stage 4 colon cancer, missed at earlier stages despite him doing screenings (75% specificity so 25% false negatives). His symptoms are basically nonexistent, it was only found due to a haemorrhoid rupturing and resulting imaging. Most colon cancer is diagnosed at stage 3 and 4, hopefully this can save a lot of lives
