Breast problems

Take appropriate measures depending on the symptoms

Common symptoms of breast trouble are lumps or swelling that hurt, and mastitis.
Please follow the instructions of an expert, such as doctors, midwives, and lactation consultants, as breast problems can lead to breastmilk insufficiency and poor weight gain in your baby.

Lumps and swelling

If you find lumps or swelling, try to breastfeed using the appropriate positioning and latch on, and breastfeed frequently. Another way to take care of lumps and swelling is to express breastmilk after and between breastfeedings. Expressing breastmilk often helps, even when the lump causes a burning pain. There is a possibility that a lump in the mammary gland will become mastitis if it is left untreated. Additionally, if your baby suddenly stops wanting breastmilk, it may be a warning of mastitis.


Mastitis is a breast disease accompanied by pain, fever (38.5 degrees C and above) and engorgement, chills, flu-like body pain and systemic symptoms.
Mastitis is said to be most common 2-3 weeks postpartum, but it can develop at any time during the breastfeeding period.
Mastitis is divided into 2 types, one with a bacterial infection and the other without.

  1. Congestive mastitis
    Stagnation mastitis (noninfectious mastitis) causes breast inflammation without bacterial infection. It is usually accompanied by redness, engorgement, lumps, a burning sensation in one breast, and sometimes a mild systemic fever. If you have these symptoms, try to breastfeed using the appropriate positioning and latch on to cope with the disruption of breastmilk.
  2. Acute purulent mastitis
    If symptoms don’t improve within 24 hours of the start of the symptoms in (1) and you have flu-like symptoms such as fever, chills and body pain, you may be infected by this bacterial form of mastitis. If the symptoms are severe, a course of antibiotics may be recommended, but in any case, see a specialist and obtain advice.
