bloomberg: Jobs’s Pancreas May Be Removed After Complications

"Surgery that Apple Inc.’s Steve Jobs may be having to remove his pancreas could be the result of painful side effects from a cancer procedure, or the return of tumors he said were removed five years ago, doctors say.

If Jobs had a so-called Whipple procedure to excise the cancer, parts of his pancreas and other organs were removed. Sometimes, damage from cancer and the surgery can spur side effects, including enzyme leaks, that worsen in time, spurring a decision to remove the entire pancreas, said Robert Thomas, head of surgery at the Peter MacCallum Cancer Centre in Melbourne.

Most often, the pancreas is removed because the cancer has returned, said Andrew Lowy, head of the division of surgical oncology at Moores Cancer Center at the University of California, San Diego. In either case, patients must take insulin, a hormone produced in the organ, for the rest of their lives, along with enzymes to help digestion, the doctors said."
