Benign (non-cancerous) breast lumps are usually caused by hormonal changes in the female’s body. Moments of hormonal change may occur during:

  • The menstrual cycle
  • Adolescence
  • The menopause
  • Pregnancy

If a woman experiences breast pain that is not linked to her menstrual cycle, it is called non-cyclic pain.

Benign (non-cancerous) breast lumps may also be cause by:

  • Mastitis – inflammationof tissue in one or both mammary glands inside the breast. Mastitis usually affects lactating women – women who are breastfeeding, producing milk. Hence, it is often referred to as lactation mastitis. The patient feels a hard, sore spot inside the breast. Mastitis can occur as a result of an infection or a blocked milk duct.
  • Nipple discharge
  • Dilated milk ducts
  • Breast injury
  • Post-operative scarring of breast tissue

Breast cancer – a tumor that has become malignant – it has developed from the breast cells. A ‘malignant’ tumor can spread to other parts of the body – it may also invade surrounding tissue. When it spreads around the body, we call it ‘metastasis’. A woman’s breast consists of lobules. Lobules are milk-producing glands. The breast is also full of ducts – milk passages that connect the lobules to the nipple. There is also fatty and connective tissue surrounding the ducts and lobules – this is called stroma.

The most common breast cancers start in the cells around the ducts. Others can start in the cells that line the lobules. A smaller number of breast cancers can start in other parts of the breast.
