'No direct evidence of link between mobile radiation and cancer'

The preponderance of evidence shows that there is no link between cell phone radiation and cancer, said oncologist and renowned author Siddhartha Mukherjee.

"I would have suggested to WHO to downgrade cell phones in the list of carcinogens but there is a process to that," Mukherjee said in a media interaction at the India International Centre here Monday.

"There are large studies which are pending, but we have to be scientifically accurate. There is no direct evidence but that does not mean that we stop investigating," he added.

Carcinogens are cancer causing substances.

The author further said that the landscape of cancer treatment has transformed over the years, and that there would be a transformation in all cancers and their treatments.
