    Tips for lumpy, painful breasts

    If you’re experiencing “clogged ducts” or your breasts are engorged, you’re probably in a lot of pain. People often get the advice to massage their breast tissue to “squeeze a plugged milk duct out,” which will make it worse.

    Why breast massage can be painful 

    Lactating breasts have incredibly robust blood supply, lymphatic vessels to drain extra fluid, nerves, connective tissue, and functional glandular tissue.  There are millions of innumerable, microscopic interlacing ducts in the breast. My hope is that providers and patients can recognize that any forceful physical manipulation of the breast simply causes MORE tissue swelling

    Squeezing your breast with force can cause worsened tissue swelling, collapse of ducts, and injury to capillaries. The breast is a gland just like the thyroid, pancreas, or adrenal gland.  Without question, we know we would injure these glands if we massaged them vigorously or handled them without delicate surgical precision in the operating room.

     

    The breast is a gland that contains blood vessels (red and blue), nerves (yellow), lymphatics (green) in addition to the functional milk-making cells. Massage damages these structures!

    What exactly is a “clogged milk duct”?

    A “plugged duct” is a collection of blood vessels, very full alveoli (the cells that produce and store milk), and tissue swelling, not a discrete “plug” of breastmilk.  Even the nipple leading to the orifice surface has countless ductules. The ROOT cause of “plugging” (i.e. often oversupply/hyperlactation or ductal narrowing/inflammation) needs to be explored and treated.

    Think of this “plug” as a group of GRAPES.

    These “grapes” represent the alveolar cells that make and store milk.  If you squeeze the grapes, you bruise them and/or turn them into grape juice.

    grapes These are “decorative” grapes I use as an example of what patients are feeling when they have an area that is “plugged.” The alveolar (milk-making and storing cells) are full and juicy. There is not a “plug” of breastmilk.

    Ice decreases swelling and blood flow, and allows the very full alveolar (milk-making cells) to become smaller and ducts to widen.

    Should I massage my breasts if I have mastitis?

    Traditional recommendations regarding mastitis unfortunately result in worsened symptoms in most patients. For example, women are instructed to breastfeed very frequently or “pump to keep their breast empty” in the setting of mastitis. Unfortunately, this stimulates more blood flow and more congestion in the setting of an already inflamed gland, and it stimulates the breast to produce more milk.  Remember that milk is made and stored in alveolar cells, not ducts.

    I tell patients to treat their breast like a sprained ankle. You wouldn’t massage a sprained ankle. You wouldn’t massage another gland like a thyroid in the setting of thyroiditis. The breast is no different.

    gland not plug
    I drained an abscess in the upper part of this patient's breast (gauze covering it), where she had massaged her breast tissue with a theragun.  She was very thin with little subcutaneous fat separating her breast gland from her skin.  All of these ridges of tissue she saw and felt (particularly in this photo in the 12:00-4:00 region in the upper outer and lower outer quadrants of her breast), she thought were "plugs."

    Ducts are microscopic, and even the biggest ones are still hard to see with the naked eye (blue arrows). If you massage a breast, you causes swelling around the ducts and worsen tissue inflammation.

    "Plug" or "Lactational Inflammatory Nodule" (LIN)
    My surgeon colleague, Rachel Yang, coined the term "Lactational Inflammatory Nodule" (LIN) to replace the term "plug" or "clog" (which isn't possible in a breast with millions of ducts).  This ultrasound image shows an area of edema (swelling) and compressed ducts within verse dense lactational tissue.

    What happens when you massage?

    When you massage an early “plug” you can develop a phlegmon (mass-like area with broken capillaries and inflammatory fluid). If massage and pumping or overfeeding continues, the phlegmon coalesces into an abscess.  

    Think of the progression like this:

    #1:  Normal grapes 

    #2:  Grapes that got smashed in your grocery bag.  It is a mix of skin, grape pulp, and liquid.  This is a PHLEGMON.

    #3:  If you were to continue smashing these grapes and adding more grapes to the mix, you would get more and more liquid and less solid material.  This is an ABSCESS.
