What's Taking So Long?


A recent paper published in Nature might provide the answer to those who wonder why we haven't cured cancer yet, blogger ERV says. The researchers did complete genome sequencing of prostate cancer tumors from seven patients with advanced or aggressive disease in order to identify possible ways to treat patients. "Yeah, it's fishing, but they were going to learn something," ERV says. "I figured genomes got pretty messy in tumors, but I don't think I fully comprehend the magnitude of the chromosomal train-wreck of 'prostate cancer'." The researchers found an average of about 108 chromosomal abnormalities in the tumors, ERV says. One patient had 213 abnormalities. "And we aren't talking a mutation here, a tiny deletion there — we are talking huge chunks of DNA in the wrong place," ERV adds. "And people wonder why we haven't cured 'cancer' yet."
