Breast massage therapy has been proven
 to assist in the promotion of healthy breast
tissue, reducing fibroids and cysts, relieving
 the pain and the discomfort associated with
 PMS or from the compression from bras,
relieving the pain and tension from stress
in the muscles of the chest wall, assist
 in the healthy tissue regeneration and
 scar reduction following surgery and as
 a logical proactive step against
cancer and other diseases. 

Breast massage might be more than a
relaxing, pleasurable experience; it
can be very good for your health.

Massage Magazine article The Evolving
Practice of Breast Massage points out the
health benefits of breast massage and the
 reasons why it's so rarely taught by all the
massage schools due to the fear it might
 be sexually-pleasurable which of course
 would be so un-professional.  And sadly
 there are even legal implications.
