Yes, you did it right. The parent comment was unfortunately incorrect. To me this is an absolute non-issue. Even if the research is free of bias and error (debatable), it's a tiny chance of cancer late in life. Spend your time worrying about almost anything else (diet, exercise, avoiding drugs), etc. and it will be orders of magnitude more important.
