Breastfeeding at 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. 2173: 557:

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.

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 a breast pump, may be a

Recent research suggests that infectious pathogens play 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

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

It has also been suggested that blocked milk ducts can occur as a result of pressure on the breast, such as tight-fitting

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

Contact should be made with 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

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 a separate entity.

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 is available and total risk increase can not be

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 and late delivery. No correlation was found with smoking status; however, this may be in

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 is mainly seen in young women but can also be seen in

Mastitis is quite common among breastfeeding women. The WHO estimates that although incidences vary between 2.6% and 33%, the prevalence globally is approximately 10% of breastfeeding women. Most mothers who develop mastitis usually do so within the first few weeks after delivery. Most breast

Although there are a number of recommendations regarding the treatment of breast abscesses, a 2015 review found insufficient evidence of whether needle aspiration is comparable to incision and drainage, or whether antibiotics should generally be given to women undergoing incision and drainage.

Breast cancer incidence during pregnancy and lactation 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.

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:

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 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.

Some predisposing factors are known but their predictive value is minimal. It appears that proper breastfeeding technique, frequent breastfeeding and avoidance of stress are the most important factors that can be influenced.

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.
