What is it?
A collection of pus in the breast, almost always secondary to a blocked duct during lactation.
What causes it?
Most breast abscesses start as a blocked milk duct in lactating women. Milk dams up behind the blockage and causes a tender, often painful, lump in the breast. When the baby feeds, the ‘let-down’ reflex produces more milk, so building up even more pressure in the blocked area. Treatment at this stage cures the condition and the dammed-up milk does not then go on to form an abscess. If nothing is done the local tissues soon become inflamed and the overlying skin is reddened. Inflammatory products get into the bloodstream and the woman has a fever. She may also feel ‘flu-like and achy. This inflammatory condition is called mastitis.
The stagnant milk in the blocked duct can easily become infected with blood-borne bacteria, so forming an abscess. The infection sometimes spreads beyond the affected duct and its gland, causing bacterial mastitis. This involves a larger area of the breast than an abscess alone.
A woman with a breast abscess has a tender lump in her breast, with some degree of inflammation around the lump. The abscess may spontaneously burst and drain its pus either down the duct to the nipple or even into breast tissue and thus to the skin of the breast.
An abscess should be treated as for a blocked duct and also with an antibiotic. It is unlikely that there will be any danger if the baby drinks the milk but some women prefer to feed only from the uninfected breast, especially if pus is draining from the nipple. The pain and other symptoms of an abscess are helped by aspirin and rest.
A condition less commonly seen nowadays is a breast abscess following infectious mastitis due to virulent bacteria entering the breast via the nipple. Modern thinking encourages less handling of babies in hospital by staff and also better hygiene precautions. These measures lower the chances of dangerous ‘hospital’ bacteria gaining access to the mother’s breast.
Prevention
This is based on treating a blocked duct promptly. Immediate and thorough action for a blocked duct prevents almost all abscesses. One major survey found that women only got an abscess if they stopped feeding when they had a blocked duct with mastitis.
• The general lowering of tension in the breast gives you a chance to unblock the duct. If you have ever had a blocked duct or feel a lumpy area of the breast developing, make sure that your breasts are soft and empty after the baby feeds.
• If your breast feels lumpy after a feed give the baby more or express the milk by hand or pump. Try to fit in twice as many feeds even if you are already feeding on demand, and don’t be afraid to let the baby suck for as long as he or she wants to. Make sure that your breasts never get over-full. If your baby is sleeping for long periods, either wake him or her to feed or else express some milk, in order to soften the breasts.
• Always offer the affected breast first to ensure efficient emptying and return to it several times during a feed as milk can be let down many times in one session.
• Most important-gently massage the lump towards the nipple to try to release the dammed-up milk. You can do this at any time-during a feed or when the baby is not at the breast. If you can, have several hot baths a day and submerge the affected breast under the water to keep it warm. Massage the lump and express the milk into the water.
• If you can’t get into a bath place a hot water bottle over the area or splash the breast with hot water while leaning over a basin. Massage and heat together work well but be careful not to burn yourself.
• Unblocking a duct (or ducts) can take several days of perseverance. When the milk is finally unblocked, it may flow freely from the nipple. You will see that it is thicker and looks whiter than your usual milk.
• Check that your bra is not pressing somewhere and causing the blocked duct. Some nursing bras with a band across the top when the flap is open can exert substantial local pressure. Be careful how you pull down the cup of an ordinary bra-that too can constrict the breast. Some women sleep on their stomach at night and the pressure on their breasts can cause a duct or ducts to block.
• Change the position in which you feed your baby from feed to feed and even during a feed so that the direction of suction is varied. Babies can suck in such a way as to leave a particular segment of the breast un-emptied at times.
• If, after 24 hours’ intensive effort as described above, the symptoms are getting worse, see your doctor at once for antibiotics, but continue the treatment as above. Don’t stop feeding.
• Rest as much as you can.
• Physical exercise, especially of the top half of the body, can help disperse the painful swelling caused by a blocked duct.
• Take 1 g vitamin Ñ a day as soon as any painful lump appears, to help combat the infection. If you find you get mastitis frequently your zinc status could be low, so go on to a full dose of zinc as recommended on the container.
• Some doctors recommend lecithin as an additive to the diet for women who repeatedly get blocked ducts.
