(NaturalNews) New research published in the journal Nature reveals that pancreatic cancer takes 20 years to grow to the point where it is diagnosed by conventional medical doctors. This was determined by sequencing the DNA of cancer tumor cells from deceased patients. Because cancer mutations occur in growing tumors at a known rate, scientists were able to map the timing of the development of full-blown pancreatic cancer tumors.

Here's what the scientists at Johns Hopkins University School of Medicine and the Howard Hughes Medical Institute found (and here's why this matters in a huge way to people interested in healthy living):

• It takes 11.7 years for one mutation in a pancreas cell to grow into a "mature" pancreatic tumor (which might show up on a medical scan).

• It takes another 6.8 years for the pancreatic tumor to spread and cause tumors to appear in other organs of the body.

In all, it takes about 20 years for a person to grow a cancer tumor and see it spread to the point where their doctor will diagnose them with pancreatic cancer.

In other words, by the time doctors diagnose you with cancer, you've already been growing it for two decades.
