In cancer detection, could a blood test replace a biopsy?
Once, when a cancer was suspected, the next move often involved a biopsy – literally cutting out human tissue to ascertain malignancy. But that highly invasive model is now being overshadowed by the promise of “liquid biopsies.” In these non-invasive approaches, blood, spinal fluid and other bodily liquids are drawn and tested for the presence of cancer cells, bits of DNA or other molecules that are the unmistakable markers of serious disease. Often, such non-invasive biopsies can be done before clinical symptoms appear.
Ash Alizadeh is an authority on the rapidly evolving technologies and techniques of oncology. He says that information is reshaping not only how we detect cancer but also how we treat it. The data we gather about any given cancer is being combined with knowledge about the patients themselves, leading to highly personalized approaches that did not exist just a few years ago. No two cancers, nor two patients, are exactly the same, Alizadeh says. Cancer cells grow differently in each patient and cancer treatments should be personalized accordingly.
