Jobs, 49, e-mailed Apple employees the surgery to remove a tumor had gone well and he would return to work in September, the New York Times reported. He said he would not need chemotherapy or radiation.
Neither the facility in which Jobs was recovering nor that where he had the procedure was disclosed.
"I had a very rare form of pancreatic cancer called an islet cell neuroendocrine tumor, which represents about 1 percent of the total cases of pancreatic cancer diagnosed each year," he wrote in the message, which Apple made public on Sunday evening, "and can be cured by surgical removal if diagnosed in time (mine was)."
Jobs founded Apple with his high school friend Stephen Wozniak in 1976, was forced to leave Apple in 1985 in a management shakeup, but returned to help rejuvenate it in 1997.
He refocused the company on its desktop and portable computers and set to work developing a modern operating system for the Macintosh. He also started an international chain of Apple stores.
