I think you may have misread the article. According your link, the American Cancer Society states that, "Men with risk factors, such as an undescended testicle, previous testicular cancer, or a family member who has had this cancer should seriously think about monthly self-exams. If you have risk factors, talk it over with a doctor. Each man has to decide for himself whether to examine his testicles each month." It also said it, "does not have a recommendation about regular testicular self-exams for all men." Perhaps you missed the "all."
