Conditions	Features	What Your Doctor May Recommend
Atypical Ductal Hyperplasia (ADH)	Abnormal cell growth	Getting more mammograms and/or seeing the doctor more often Taking tamoxifen
Cancer	Abnormal cells dividing without control in the breast Could spread to other parts of the body	Surgery Chemotherapy Radiation therapy Hormonal therapy Biological therapy Treatment may depend on the stage of the disease
Ductal Carcinoma In Situ (DCIS)	Cancer cells in the breast ducts Has not spread to other parts of the breast May develop into cancer that spreads to other parts of the breast (invasive breast cancer)	Breast-sparing surgery and radiation therapy (with or without tamoxifen) Breast-sparing surgery without radiation therapy (with or without tamoxifen) Total mastectomy (with or without tamoxifen)
Fat Necrosis	Painless, round, firm lumps Formed by damaged fatty tissue May occur after surgery to the breast Often occurs in response to a bruise or blow to the breast, although a woman might not recall being injured	Sometimes removed with surgical biopsy because it can look like cancer
Fibroadenoma	Hard, round, benign growth Feels like rubber; moves around easily Usually painless Often found by the woman herself Appears on mammogram as smooth, round lumps with clearly defined edges Can get bigger when the woman is pregnant or nursing	Sometimes diagnosed with fine-needle aspiration If the fibroadenoma does not appear normal, the doctor may suggest taking it out to make sure it is benign
Intraductal Papilloma	Growth inside the nipple that looks like a wart May cause nipple discharge	Surgery to remove the growth
Lobular Carcinoma In Situ (LCIS)	Abnormal cells found in the lobules Not cancerous but associated with a greater chance of getting cancer in either breast in the future	Regular check-ups to look for signs of breast cancer Tamoxifen may be suggested Evaluation of breast cancer risk by your doctor
Sclerosing Adenosis	Too much tissue growth in lobules Can contain calcifications Often painful Changes usually very small but can produce lumps	Clinical breast exam Annual mammogram More tests if breast changes are noted on breast self-exam, clinical breast exam, or mammogram
