Laser treatment for cracked and grazed nipples appears to be becoming more
popular here (Perth, Western Australia) in a similar way as ultrasound
treatment has been for mastitis. I became aware of it about a year ago when
a new physiotherapist started at the hospital who was very eager to use it
as a treatment for affected mothers. She gave me pages of written
information and although referenced in the text, had no full end references
to refer to. I will give a short summary of the information based on this
info. Low Intensity Laser Therapy (LILT) has been historically used in
assisting tissue repair in chronic pressure sores. Apparently certain
wavelengths of light have a profound effect on cell function with photons
being absorbed within the cell mitochondria and cell membranes. Low powered
lasers are used (typically 0.1 to 0.001 Watts). They apparently have only a
photochemical effect, no thermal effect. The literature reported LILT to
have been seen to have many biochemical and physiological effects such as
changing cell membrane permeability to various ions, changing mitochondrial
membrane permeability leading to increased cellular ATP levels and
increasing endothelial cell and fibroblast proliferation. Many other
chemicals have been observed to increase such as bradykinin, serotonin,
endorphins.....I could go on, but the up shot is they believe it facilitates
rapid healing and increases comfort levels and is of special value in
treating chronic wounds.
I have great reservations about its use on the nipple as its possible
effects on milk and breast tissue is unknown and its therapeutic effects in
this area are unproven. I have said to the physiotherapist that I am not in
favour of its use at this time but if she wishes to offer the treatment then
it should be with the information that there is no research to show proven
therapeutic results in the treatment of cracked nipples and that any such
treatment must only be given once the cause of the problem has been
established and a plan of care in situ. She apparently has a colleague at a
major teaching maternity hospital who is hoping soon to do some research in
this area as part of her post graduate studies.
Hope this information is of help to those inquiring.
