How can the genes on chromosome 17 (death chromosome) relate to cancer?

Junk science. I'm glad you're reading science and I'm sorry you picked up a sensational, garbage article about one in particular being the 'death chromosome'. There's a bunch of loci including ERBB2, NF1 and TP53; the last one is the most-often knocked out in the nastiest cancers. Keep reading and your discernment will improve. Best wishes.
