Mastitis

Mastitis - What it is

mastitis conditions & treatments

Mastitis is usually an infection of the breast tissues. It is common in breastfeeding women.

It can occur anytime during lactation but is more common in the first 3 months of lactation. About up to 10 percent of women who breastfeed may be affected.

Idiopathic Granulomatous Mastitis (IGM)

Women not lactating or breastfeeding can also get mastitis. In some of these women, the cause is unknown. This may be resolved with a course of antibiotics, but if IGM persists, it may become complicated and abscesses may result. Surgery to drain the infection and to obtain tissue for biopsy may be needed.

In some severe cases, steroid therapy may be considered if an infective cause is excluded.

Mastitis - Symptoms

Symptoms include:

  • Breast pain
  • Swelling
  • Redness and warmth
  • Development of a breast lump
  • Fever, chills and tiredness

Mastitis - How to prevent?

​Women are encouraged to breastfeed frequently, especially when breasts feel engorged. Try to ensure that your baby latches on properly during feeding and allow the baby to finish feeding.

Avoid pressure on the breasts e.g. tight bra/clothing and adjust breastfeeding techniques to avoid breast engorgement.

Mastitis - Causes and Risk Factors

Causes of Mastitis

​​This may be from a blocked milk duct, or bacteria that enters the breast tissue through cracks or breaks in the skin or nipple.

Risk Factors of Mastitis

Mastitis is most often related to:

  • Breastfeeding
  • Sore or cracked nipples
  • Using only one position to feed
  • Wearing a tight bra that may restrict milk flow
  • Mastitis not related to breastfeeding may be seen in women with diabetes mellitus

Mastitis - Diagnosis

​Diagnosis is made on assessment of history and by clinical physical examination. Breast imaging such as breast ultrasound may be needed to assess for abscess formation (collection of pus material within the breast).

Mammograms are usually not needed and can be uncomfortable. A biopsy may be indicated if symptoms persist after a course of antibiotics.

Mastitis - Treatments

​Antibiotics and pain relief are the main courses of treatment. Usually a course of oral antibiotics is sufficient. However, if the condition persists or worsens, intravenous antibiotics may be required. If it is not treated adequately, an abscess may form and this may require surgical drainage.
