Finding a breast lump can be concerning. A common question is whether its movement indicates if it’s cancerous. This article explores breast lump characteristics, focusing on mobility, and outlines steps to take if a lump is discovered.
Understanding Breast Lumps
Breast tissue has a varied texture, and not all lumps are cause for alarm. Many common breast lumps are benign, meaning they are non-cancerous growths. These include fluid-filled sacs known as cysts, which often feel soft or rubbery and can fluctuate in size with the menstrual cycle.
Another frequent type of benign lump is a fibroadenoma, a solid tumor composed of glandular and fibrous tissue. Fibroadenomas typically present as firm, smooth, and rubbery masses that move freely under the skin.
The Significance of Lump Mobility
The mobility of a breast lump is a characteristic often considered, but it is not a definitive indicator of whether a lump is cancerous or benign. Many benign lumps, such as cysts and fibroadenomas, are often described as movable or “slippery” when felt. This characteristic often leads to the misconception that any movable lump is benign.
However, some cancerous lumps can also exhibit a degree of mobility, particularly if they are small or located superficially. Conversely, certain benign lumps, especially those that are larger or embedded deeply, might feel fixed. Cancerous lumps often become fixed when they begin to invade surrounding tissues, anchoring themselves in place. Relying solely on mobility to assess a lump’s nature can be misleading.
Other Key Indicators
Since mobility alone does not definitively indicate a lump’s nature, other characteristics and symptoms warrant attention. Changes in the lump itself, such as increased size, irregular shape, or hardening, are significant. A lump that feels firm and fixed to the chest wall or skin is more concerning.
Skin changes on the breast are also important indicators. These include dimpling, redness, skin thickening, or a texture resembling an orange peel. Nipple changes, such as inversion, discharge, persistent redness, or scaling, also warrant medical evaluation. Persistent pain in the breast or armpit that does not resolve should be discussed with a healthcare professional.
Next Steps After Finding a Lump
If any new lump or unusual changes are noticed in the breast, consult a healthcare professional promptly. This applies regardless of whether the lump feels movable or fixed. Early evaluation is important for determining the nature of any breast change.
A healthcare provider will begin with a clinical breast exam, manually checking the breasts and armpits for lumps or other changes. Further diagnostic steps may include imaging tests like a mammogram, ultrasound, or MRI. If these tests indicate a suspicious area, a biopsy (taking a small tissue sample for laboratory analysis) may be recommended for a definitive diagnosis.
