That should not be a shock Gwap it's been well known and published for a hell of a long time, the rate will increase with time as the older you get the poorer your DNA replication becomes i.e. the more mistakes are made in each new copy of a cell, think photocopy of a photocopy of a photocopy, they look like crap by the time you get to the third or fourth iteration. As more and more people live to great age the more cancer will be the ultimate cause of death.
And the reason you get old is exactly the same, cells make mistakes, skin becomes less elastic, hair follicles become less prolific, hormones levels change because the glands making them change, cancer happens ultimately because cells make mistakes, sometime serious mistakes, when making copies of themselves, it's life you just have to accept it, generally we are living longer so more of us will die of cancer.
You should also understand that controlled drugs still have a place in medicine, controlled drugs can still be therapeutic.
