Topics referred to by
104-448: A breast pump , and weaning . The bacteria most commonly involved are Staphylococcus and Streptococci . Diagnosis is typically based on symptoms. Ultrasound may be useful for detecting a potential abscess. Prevention of this breastfeeding difficulty is by proper breastfeeding techniques. When infection is present, antibiotics such as cephalexin may be recommended. Breastfeeding should typically be continued, as emptying
156-425: A microscope ( biopsy ). The sampling and biopsy considered together are called fine-needle aspiration biopsy ( FNAB ) or fine-needle aspiration cytology ( FNAC ) (the latter to emphasize that any aspiration biopsy involves cytopathology , not histopathology ). Fine-needle aspiration biopsies are very safe minor surgical procedures. Often, a major surgical (excisional or open) biopsy can be avoided by performing
208-407: A sensory processing disorder , postpartum depression , perinatal anxiety , dysphoric milk ejection reflex , an involuntary aversion to breastfeeding, or other mental health problems. Breast cancer may coincide with or mimic symptoms of mastitis. Only full resolution of symptoms and careful examination are sufficient to exclude the diagnosis of breast cancer. The lifetime risk for breast cancer
260-431: A breast pump, may be a risk factor for recurrent mastitis. Probiotics may or may not help, but they are believed not to be harmful. Over-the-counter nonsteroidal anti-inflammatory drugs , such as ibuprofen and paracetamol , may reduce inflammation. Antibiotics are appropriate only for bacterial mastitis, which may develop if non-infective mastitis does not improve. Antifungals are similarly only useful when
312-445: A clear image of the breast tissue and may be helpful in distinguishing between simple mastitis and abscess or in diagnosing an abscess deep in the breast. The test consists of placing an ultrasound probe over the breast. In cases of infectious mastitis, cultures may be needed in order to determine what type of organism is causing the infection. Cultures are helpful in deciding the specific type of antibiotics that will be used in curing
364-642: A fungal infection, such as thrush , is present. Severe infections may require ordinary medical supportive care , such as intravenous fluids if the mother is unable to drink enough water or other fluids. Therapeutic ultrasound may reduce swelling. The shape of swelling in a specific spot may make people suppose that the breasts contain simple tubes, and that one has become plugged. However, milk ducts are not simple tubes, and their interconnected anatomy makes it impossible for them to actually become plugged. Consequently, treatment does not include cutting, popping, or squeezing any so-called "plugged" ducts. There
416-478: A health care provider with special breastfeeding competence as soon as the patient recognizes the combination of signs and symptoms. Most of the women first experience the flu-like symptoms and just after they may notice a sore red area on the breast. Also, women should seek medical care if they notice any abnormal discharge from the nipples , if breast pain is making it difficult to function each day, or they have prolonged, unexplained breast pain. A breast abscess
468-420: A much smaller role in the pathogenesis than was commonly assumed only a few years ago. Most detected pathogens are very common species that are natural part of the breast fauna and simple detection of their presence is not sufficient to prove a causative role. Furthermore, there are indications that treatment with antibiotics may have minimal impact, and over-all there is insufficient evidence to confirm or refute
520-569: A needle aspiration biopsy instead, eliminating the need for hospitalization. In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center . Today, this procedure is widely used in the diagnosis of cancer and inflammatory conditions. Fine needle aspiration is generally considered a safe procedure. Complications are infrequent. Aspiration is safer and far less traumatic than an open biopsy; complications beyond bruising and soreness are rare. However,
572-451: A normal level may provide temporary relief from the swelling without triggering milk oversupply. It is safer to treat nipple blebs (very small, usually pale colored, bumps of tissue on the end of the nipple) with topical steroids than by cutting the skin. Any action that breaks the skin can cause an infection, which increases inflammation and may become serious. Antibiotics do not prevent mastitis from recurring. Nonpuerperal mastitis

#1732772030910624-428: A nursing infant to latch on to the breast can also increase the risk for mastitis. Women with diabetes , chronic illness , AIDS , or an impaired immune system may be more susceptible to the development of mastitis. Some women (approximately 15%) will require antibiotic treatment for infection which is usually caused by bacteria from the skin or the baby's mouth entering the milk ducts through skin lesions of
676-537: A secondary infection (see the section on the treatment of breast abscess in this article). Keratinizing squamous metaplasia of lactiferous ducts may play a similar role in the pathogenesis of nonpuerperal subareolar abscess . Since the 1980s mastitis has often been divided into non-infectious and infectious sub-groups. However, recent research suggests that it may not be feasible to make divisions in this way. It has been shown that types and amounts of potentially pathogenic bacteria in breast milk are not correlated to
728-441: A separate entity. Names for non-puerperal mastitis are not used very consistently and include mastitis, subareolar abscess, duct ectasia, periductal inflammation, Zuska's disease and others. Periductal mastitis is a form of nonlactational mastitis, and is characterized by inflammation of the subareolar ducts. Although the cause of periductal mastitis is currently unknown, it is predicted that smoking may be related. This condition
780-405: Is inflammation of the breast or udder , usually associated with breastfeeding . Symptoms typically include local pain and redness. There is often an associated fever and general soreness. Onset is typically fairly rapid and usually occurs within the first few months of delivery. Complications can include abscess formation. Risk factors include poor latch , cracked nipples , use of
832-494: Is a collection of pus that develops in the breast with various causes. During lactation, breast abscess develops only rarely, most sources cite about 0.4–0.5% of breastfeeding women. Known risk factors are age over 30, primiparous (first birth) and late delivery. No correlation was found with smoking status; however, this may be in part because far fewer smoking women choose to breastfeed. Antibiotics were not shown effective in prevention of lactation abscess but are useful to treat
884-406: Is a minimally invasive procedure for acquiring biopsies in gastric regions that are hard to reach otherwise (e.g. the pancreas). Endoscopic ultrasound EUS-FNA of cystic lesions, followed by liquid cell analysis, has been used as a diagnostic tool for differentiating benign, potentially malignant, and malignant pancreatic cysts. 'Through-the-needle' cytologic brushes have been developed for increasing
936-467: Is associated with breastfeeding, the treatment has to balance short-term reduction of symptoms with solving the underlying problems that caused mastitis. For example, the Academy of Breastfeeding Medicine recommends against trying to "empty" the breasts, whether through pushing the baby to feed more or through using a breast pump . It may reduce the feeling of being full or swollen in the short term, at
988-479: Is assumed to be the same as in controls. Course and prognosis are also very similar to age matched controls. However diagnosis during lactation is particularly problematic, often leading to delayed diagnosis and treatment. Some data suggest that noninflammatory breast cancer incidence is increased within a year following episodes of nonpuerperal mastitis and special care is required for follow-up cancer prevention screening. So far only data from short term observation
1040-427: Is available and total risk increase can not be judged. Because of the very short time between presentation of mastitis and breast cancer in this study it is considered very unlikely that the inflammation had any substantial role in carcinogenesis, rather it would appear that some precancerous lesions may increase the risk of inflammation ( hyperplasia causing duct obstruction, hypersensitivity to cytokines or hormones) or
1092-433: Is different from Wikidata All article disambiguation pages All disambiguation pages Fine-needle aspiration cytology Fine-needle aspiration ( FNA ) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under
SECTION 20
#17327720309101144-415: Is mainly seen in young women but can also be seen in men. Lactation mastitis usually affects only one breast and the symptoms can develop quickly. It develops into three stages, from the initial stage, the pus formation stage, to the restoration stage. The signs and symptoms usually appear suddenly and they include: Some women may also experience flu -like symptoms such as: Contact should be made with
1196-598: Is minimal. It appears that proper breastfeeding technique, frequent breastfeeding and avoidance of stress are the most important factors that can be influenced. Light cases of mastitis are often called breast engorgement ; the distinction is overlapping and possibly arbitrary or subject to regional variations. The term nonpuerperal mastitis describes inflammatory lesions of the breast occurring unrelated to pregnancy and breastfeeding. This article includes description of mastitis as well as various kinds of mammary abscesses. Skin related conditions like dermatitis and foliculitis are
1248-409: Is no "plug" (e.g., of dried-out milk) to be removed. These localized swellings are usually caused by lymphatic congestion (non-milk body fluid accumulating in the breasts), alveolar edema (swelling in the part of the breast that produces milk), or mammary dysbiosis (changes to the breast's microbiome ), which can cause some narrowing, but not plugging, at the microscopic level. Breastfeeding at
1300-525: Is recommended. The length of antibiotic treatment ranges anywhere from 5–14 days. The effects of antibiotics has not been well studied as of 2013. A lactational phlegmon (area of inflammation) should be monitored for possible development into an abscess (walled-off area filled with pus from an infection). An abscess (or suspected abscess) in the breast may be treated by ultrasound -guided fine-needle aspiration (percutaneous aspiration) or by surgical incision and drainage ; each of these approaches
1352-454: Is significantly reduced for women who were pregnant and breastfeeding. Mastitis episodes do not appear to influence lifetime risk of breast cancer. Mastitis does however cause great difficulties in diagnosis of breast cancer. Breast cancer may coincide with mastitis or develop shortly afterwards. All suspicious symptoms that do not completely disappear within 5 weeks must be investigated. Breast cancer incidence during pregnancy and lactation
1404-462: Is the inflammation of the breast in connection with pregnancy, breastfeeding or weaning. Since one of the most prominent symptoms is tension and engorgement of the breast, it is thought to be caused by blocked milk ducts or milk excess. It is relatively common; estimates range depending on methodology between 5–33%. However, only about 0.4–0.5% of breastfeeding mothers develop an abscess. Some predisposing factors are known but their predictive value
1456-475: Is the most common complication of this procedure. A slight bruise may also appear. If a lung or kidney biopsy has been performed, it is very common to see a small amount of blood in sputum or urine after the procedure. Only a small amount of bleeding should occur. During the observation period after the procedure, bleeding should decrease over time. If more bleeding occurs, this will be monitored until it subsides. Rarely, major surgery will be necessary to stop
1508-531: Is treated by medication and possibly aspiration or drainage (see in particular treatment of subareolar abscess and treatment of granulomatous mastitis ). According to a BMJ best practice report, antibiotics are generally to be used in all mastitis cases unrelated to breastfeeding, with replacement of the antibiotics by an antifungal agent such as fluconazole in cases of deep fungal infections, and corticosteroids are to be used in case of granulomatous mastitis (with differential diagnosis to tuberculosis infection of
1560-473: Is typically performed in the operating room and starts by transferring an aliquot of the FNA sample onto a glass slide. Then, the sample is manually smeared out to obtain a thin sample layer with cells dispersed along the glass slide. After an air-drying step, the sample is stained, typically with a rapid Romanowky-type stain. Finally, a morphological assessment of the stained cells under a microscope allows to evaluate
1612-509: The adequacy of the collected FNA sample. Research focuses, among other, on portable devices for semi-automated sample preparation for ROSE, with the purpose to simplify the performance of FNA sample preparation and reach to a wider implementation of ROSE. As with any surgical procedure, complications are possible, but major complications due to thin-needle aspiration biopsies are fairly uncommon, and when complications do occur, they are generally mild. The kind and severity of complications depend on

1664-486: The baby has infrequent feeds or has problems suckling the milk out of the breast. The presence of cracks or sores on the nipples increases the likelihood of infection. There is a possibility that infants carrying infectious pathogens in their noses can infect their mothers; the clinical significance of this finding is still unknown. Mastitis can also develop due to contamination of a breast implant or any other foreign body, for example after nipple piercing . In such cases,
1716-464: The bleeding. Other complications depend upon the body part on which the biopsy takes place: A study published in 2004 showed that in one case, a needle biopsy of a liver tumor resulted in the spread of the cancer along the path of the needle and concluded that needle aspiration was dangerous and unnecessary. The conclusions drawn from this paper were subsequently strongly criticized. Lung Neck Bone Risk Breast abscess Mastitis
1768-659: The breast is important for healing. Tentative evidence supports benefits from probiotics . About 10% of breastfeeding women are affected. When it occurs in breastfeeding mothers, it is known as puerperal mastitis , lactation mastitis , or lactational mastitis . When it occurs in non breastfeeding women it is known as non-puerperal or non-lactational mastitis . Mastitis can, in rare cases, occur in men. Inflammatory breast cancer has symptoms very similar to mastitis and must be ruled out. The symptoms are similar for puerperal and nonpuerperal mastitis but predisposing factors and treatment can be very different. Puerperal mastitis
1820-434: The breast was sometimes cooled by placing a cabbage leaf on the breast, but this is now more commonly done with an ice pack or a wet washcloth . Gentle massage ("like petting a cat" ) may be comfortable and may reduce swelling. However, more aggressive rubbing can easily damage breast tissues that are already strained by mastitis, and that damage can increase swelling and pain. Excessive massage, like excessive use of
1872-449: The breast). In idiopathic granulomatous mastitis , successful treatment includes invasive surgical procedures or less invasive treatment with steroid medications. In lactational mastitis, antibiotics are not needed in the overwhelming majority of cases and should be used only for bacterial infections. For people with non-severe infections, dicloxacillin or cephalexin are recommended. For people with severe infections, vancomycin
1924-425: The cellular content in the aspirates. Rapid on-site evaluation (ROSE) is a real-time service during EUS-FNA interventions, that assesses the adequacy of the collected biopsy samples for diagnostics. Sample adequacy is deemed by the number of target cells that allow determining tumor malignancy. ROSE reduces the overall number of needle passes required for an appropriate sample and the number of FNA procedures. ROSE
1976-425: The cost of triggering milk oversupply , which can cause a mastitis recurrence in the coming days and weeks. For breastfeeding women with breast engorgement or light mastitis, using a warm compress may be comfortable. However, by increasing blood flow to the area, warm compresses make the symptoms worse for other women. A cool compresses can reduce edema (swelling) and pain. In traditional folk medicine ,
2028-522: The disease. These cultures may be taken either from the breast milk or of the material aspirated from an abscess. Mammograms or breast biopsies are normally performed on women who do not respond to treatment or on non-breastfeeding women. This type of tests is sometimes ordered to exclude the possibility of a rare type of breast cancer which causes symptoms similar to those of mastitis. Some women who experience pain or other symptoms when breastfeeding, but who have no detectable signs of mastitis, may have
2080-404: The effectiveness of antibiotic therapy for treating lactational mastitis. The diagnosis of mastitis and breast abscess can usually be made based on a physical examination . The doctor will also take into account the signs and symptoms of the condition. However, if the doctor is not sure whether the mass is an abscess or a tumor , a breast ultrasound may be performed. The ultrasound provides
2132-486: The few problematic cells can be too few (inconclusive) or missed entirely (a false negative ). This type of sampling is performed for one of two reasons: When the lump can be felt, the biopsy is usually performed by a cytopathologist or a surgeon . In this case, the procedure is usually short and simple. Otherwise, it may be performed by an interventional radiologist , a doctor with training in performing such biopsies under x-ray or ultrasound guidance. In this case,

2184-408: The lesions may have common predisposing factors. A very serious type of breast cancer called inflammatory breast cancer presents with similar symptoms as mastitis (both puerperal and nonpuerperal). It is the most aggressive type of breast cancer with the highest mortality rate. The inflammatory phenotype of IBC is thought to be mostly caused by invasion and blocking of dermal lymphatics, however it
2236-510: The mass for biopsy, using x-rays or palpation , a special needle of very fine diameter is passed into the mass. The needle may be inserted and withdrawn several times. There are many reasons for this: After the needles are placed into the mass, cells are withdrawn by aspiration with a syringe and spread on a glass slide. The patient's vital signs are taken again, and the patient is removed to an observation area for three to five hours. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA)
2288-429: The milk ducts in the breasts becoming blocked, as the breast milk is not being properly and regularly expressed. It has also been suggested that blocked milk ducts can occur as a result of pressure on the breast, such as tight-fitting clothing or an over-restrictive bra, although there is sparse evidence for this supposition. Mastitis may occur when the baby is not appropriately attached to the breast while feeding, when
2340-451: The nature of the biopsy, an intravenous line may be placed. Very anxious patients can be sedated through this line, or oral medication ( Valium ) may be prescribed. The skin above the area to be biopsied is swabbed with an antiseptic solution and draped with sterile surgical towels. The skin, underlying fat , and muscle may be numbed with a local anesthetic , although this is often not necessary with superficial masses. After locating
2392-462: The nipple or through the opening of the nipple. Infection is usually caused by Staphylococcus aureus . Infectious pathogens commonly associated with mastitis are Staphylococcus aureus , Streptococcus spp. and Gram-negative bacilli such as Escherichia coli . Salmonella spp. , mycobacteria , and fungi such as Candida and Cryptococcus have been identified in rare instances. Recent research suggests that infectious pathogens play
2444-476: The organs from which a biopsy is taken or the organs gone through to obtain cells. After the procedure, mild analgesics are used to control post-operative pain. Aspirin or aspirin substitutes should not be taken for 48 hours after the procedure (unless aspirin is prescribed for a cardiac or neurological condition). Since sterility is maintained throughout the procedure, infection is rare. But should an infection occur, it will be treated with antibiotics . Bleeding
2496-462: The procedure may require more extensive preparation and take more time to perform. Also, fine-needle aspiration is the main method used for chorionic villus sampling , as well as for many types of body fluid sampling . It is also used for ultrasound-guided aspiration of breast abscess , of breast cysts , and of seromas . Before the procedure is started, vital signs ( pulse , blood pressure , temperature, etc.) may be taken. Then, depending on
2548-401: The removal of the foreign body is indicated. Women who are breastfeeding are at risk for developing mastitis especially if they have sore or cracked nipples or have had mastitis before while breastfeeding another baby. Also, the chances of getting mastitis increases if women use only one position to breastfeed or wear a tight-fitting bra, which may restrict milk flow Difficulties in getting

2652-482: The severity of symptoms. Moreover, although only 15% of women with mastitis in Kvist et al.'s study were given antibiotics, all recovered and few had recurring symptoms. Many healthy breastfeeding women wishing to donate breast milk have potentially pathogenic bacteria in their milk but have no symptoms of mastitis. Mastitis typically develops when the milk is not properly removed from the breast. Milk stasis can lead to
