The risk-free magic bullet hasn't been invented yet. Cancer therapy for children prolongs precious lives for decades, but there can be ramifications years later, as described in an article by Dawn Fallik in today's Wall Street Journal. Here's a portion of that article:
"The biggest risk is believed to come from a class of drugs called anthracyclines, one of oncology’s workhorse chemotherapies that is effective against leukemia and a wide range of other cancers. The drugs’ toxic effect on the heart is well-established in adults. That they have similar effects in children is now becoming increasingly understood as these patients reach adulthood. Radiation treatments also come with risk of long-term side effects, especially when given in combination with anthracyclines."
