Breast reduction at age 70. Am I too old?

No- as long as you're medically cleared for surgery and as long as you are a good candidate. I recommend scheduling an in person consultation with an experienced Board Certified PS. For more info about breast reduction you can view this link:

Age alone is never a contraindication to surgery even breast reduction surgery.  Whether or not you should undergo breast reduction surgery is more a matter of your general health.  If you are other wise healthy and do not have significant comorbidities (other health issues) you should consider it especially  if you've come to the conclusion that your breast size has detracted from you ability to enjoy life to the fullest. However, it is imperative that you discuss this with your primary physician and he is in agreement.
