This is fungal growth. I presume you live in a hot humid place like Florida or Houston. The fungus grows on the glue that holds lens elements together. Cleaning is very expensive or impossible. However, Canon my be able to replace the elements with the problem.

By the way, the degree of fungal growth visible is not likely to affect your results. Unfortunately, the fungal growth will continue until it makes your lens useless.
