Pancreatic cancer

Jobs is currently on his third medical leave to deal with health issues.

The Apple CEO announced in late January that "at my request, the board of directors has granted me a medical leave of absence so I can focus on my health".

Steve Jobs has been battling serious health issues over seven years.

In August 2004, Jobs underwent successful surgery to treat a rare form of pancreatic cancer, which laid him up until September of that year. He had also undergone a liver transplant in 2009.

The rumors doing the rounds are that he is once again stricken with the malignancy.

Asthma patients are 30 percent less likely to contract ovarian cancer while kids with airborne allergies are almost 40 percent less likely to get leukemia, throat, skin and lung cancer than others.

An allergy like hay fever further reduced the chance of having pancreatic cancer by 58 percent, claim researchers.

A team at Brigham Young University saw a lower risk of non-Hodgkin's lymphoma and stomach cancer, while Harvard epidemiologists "observed a strong inverse relationship" between brain cancer and asthma, eczema, hay fever or allergy.

Dwelling on the co-relation between consuming sugary drinks, and pancreatic cancer, the scientists believe that the dissolved sugar is quickly carried to the bloodstream, where its presence triggers blood sugar levels.

This in turn signals the pancreas to go into overdrive to pump out as much insulin as it can.

Study leader Dr Mark Pereira, from the School of Public Health at the University of Minnesota in the US, said, “The high levels of sugar in soft drinks may be increasing the level of insulin in the body, which we think contributes to pancreatic cancer cell growth.
