What Causes Breast Lumps?

Breast lumps can have various causes, and while some may be benign (non-cancerous), others can be indicative of breast cancer. It’s important to note that the presence of a breast lump should always be evaluated by a healthcare professional for an accurate diagnosis. Common causes of breast lumps include:

  • Fibrocystic Changes: Many women experience fibrocystic breast changes, especially during their menstrual cycle. These changes can lead to the development of fluid-filled cysts or fibrous tissue, resulting in lumps or areas of lumpiness. These changes are generally benign and not associated with an increased risk of breast cancer.
  • Fibroadenomas: Fibroadenomas are benign breast tumors made up of glandular and connective tissue. They are usually painless and can be moved under the skin. Fibroadenomas are common among women in their twenties and thirties.
  • Breast Infections: Infections of the breast, such as mastitis or abscesses, can cause painful lumps. These infections are more common in women who are breastfeeding.
  • Cysts: Fluid-filled sacs or cysts can develop in the breast tissue. They are often associated with hormonal changes and can vary in size. Cysts can be painful and may change in size during the menstrual cycle.
  • Fat Necrosis: Trauma or injury to the breast tissue can lead to fat necrosis, where the fatty tissue in the breast forms a lump. This can sometimes be associated with pain and skin changes.
  • Breast Cancer: Breast cancer is a less common but significant cause of breast lumps. While many breast lumps are benign, it’s essential to have any new or unusual breast lump evaluated by a healthcare provider, as early detection and diagnosis of breast cancer are critical for successful treatment.
  • Hormonal Changes: Hormonal fluctuations, such as those associated with menopause, can lead to changes in breast tissue and the development of lumps or thickening.
  • Breast Implants: In some cases, breast implants can cause lumps or changes in breast tissue. These should be evaluated by a healthcare provider to determine the cause.
  • Other Conditions: Rarely, other benign breast conditions, such as papillomas or phyllodes tumors, can cause breast lumps.

If you discover a breast lump or experience changes in your breast tissue, it’s essential to seek medical attention promptly. Your healthcare provider may perform a clinical breast examination, order imaging tests (such as mammography, ultrasound, or MRI), and, in some cases, recommend a biopsy to determine the nature of the lump.

Remember that the majority of breast lumps are benign, but any new or concerning lump should be evaluated to rule out breast cancer or other serious conditions. Regular breast self-exams and mammograms (as recommended by your healthcare provider) can aid in early detection and early intervention if necessary.
