Good advice about weights and yoga. Mentors like me are reading these posts, and commenting from time to time. Medical advice is not given here, just shared personal experience. I'm not sure exactly which questions you are asking. But, for example, your oncologist is probably the best person to consult with about taking the letrozole every other day. But I am going to pass this on to a Moderator who might have some suggestions about links and articles related to Mayo and lobular cancer. Thanks for adding to the discussion.
