Common causes of breast lumps
- Cysts, fluid-filled sacs that often change with the menstrual cycle
- Fibroadenomas, smooth, rubbery benign growths common in younger women
- Fibrocystic changes, lumpy or tender breast tissue
- Fat necrosis after an injury or surgery
- Breast cancer, which is why every new lump should be evaluated
What happens at your visit
Dr. Arsenous will ask about the lump, any changes you have noticed, your menstrual cycle, your family history and previous imaging. She will examine both breasts and the lymph nodes under the arms and above the collarbone.
Imaging is usually the next step. Women under 30 often start with an ultrasound; older women usually have a diagnostic mammogram and ultrasound. Bring any previous mammograms or reports, as comparison is very helpful.
Talk with Dr. Arsenous about your options.
When is a biopsy needed?
A biopsy is recommended when imaging shows a solid mass or an area that cannot be confidently called benign. Most are done with a needle under ultrasound or mammogram guidance and take less than an hour. Learn more about breast biopsy or read when a breast lump should be biopsied.
