5-alpha reductase inhibitors - no risk of male breast cancer.


Recommended Posts

Jim Marshall (not a doctor) said ...

Taking 5-alpha reductase inhibitors, like Proscar or Propecia (finasteride) and Avodart (dutasteride) does not increase the risk of breast cancer in men.

These drugs, sometimes used for male hair loss, and for shrinking the size of large prostates without cancer, are also used in prostate cancer prevention and treatment.  Despite a clear anti-prostate cancer effect, the use of these drugs is controversial, with some oncologists (Dr Snuffy Myers is one) in favour, and others concerned about their use. The FDA has issued a warning to be placed on every pack.

A fuller account of 5-alpha reductase inhibitors (not related to this ASCO paper) can be found on member Chuck's Maack's site (http://tinyurl.com/n8a3yxj). (Chuck is also not a doctor.)

This extract was published in association with the American Society of Clinical Oncology 2013 annual conference. Though the research behind it may have been excellent, your doctor cannot yet give much weight to it for a number of reasons, including:

  • It is only an extract. The full paper may reveal information important for your treatment.
  • The study has not yet had peer review - with doctors and researchers scrutinising the study closely for mistakes and limitations after it is published in a professional journal.
  •  Your doctor may already be aware of a limitations of the findings because of their wider reading.
