It's very poorly written.
The article says walking 45 minutes a day reduces the risk for "3% of common cancers." That makes it sound like if there were, say, 100 common cancers, walking would reduce the risk for only 3 TYPES of cancer.
Later, the article states, "That number turned out to be 46,356, or about 3% of all cancers annually (excluding non-melanoma - skin cancers)." Now we're talking about a completely different 3%; 3% of the TOTAL number of all cancer CASES.
