Women younger than age 35
Mammography is not helpful in women under age 35 because the breast tissue is too dense for the
mammographer to read clearly. In a young woman with no physical findings indicating malignancy, it is reasonable to ask that the patient return 3 to 10 days after the next menstruation begins to determine if the lump regresses.

- If the lump does not feel cystic, the patient should be referred for ultrasound. If ultrasound shows a solid mass, the patient should undergo either FNAB, core needle biopsy, or excisional biopsy, depending upon local expertise. Some experts suggest that if a solid lump is small (<1 cm in size) and is not clinically suspicious (eg, is soft, not fixed, not new, and not changing) the lump is likely to be a fibroadenoma and the patient can be followed with physical examination every 3 to 6 months.
- Sometimes, general lumpiness rather than a distinct lump is felt. A second opinion should be sought in such a situation
- Women who have had breast cysts are at higher than expected risk for the later development of breast cancer However, because the absolute risk remains small, increased breast cancer surveillance for young women who have had documented breast cysts is not recommended at this time.
