Breast lumps: These are typically found on breast self exams or clinical breast exams.  The majority of breast lumps especially in younger women tend to be benign.  It is important to follow up with a health care provider to evaluate any new breast masses that have been found.  

Simple cysts:  These tend to fluctuates with menstrual cycles.  A woman may suddenly notice a lump suddenly that is tender especially before the menstrual cycle and resolve once the cycle begins.  If the cyst is very large and/or painful a cyst aspiration can be performed in the office.  
 
Fibroadenomas:  These are benign stromal tumor.  These masses do not put patients at risk of breast cancer.  However, if you have one you are at a higher risk of developing more.  Typically, management of these masses can be close observation with serial ultrasounds and clinical breast exams.  If there is an increase size in growth, then it should be excised.  Or if the patient does not want to watch and wait then an excision is recommended.  
 
Nipple Discharge:  Nipple discharge can be divided into two categories physiologic and pathologic.  Physiologic nipple discharge typically is non-spontaneous and usually after the breast has been massaged.  The discharge is seen out of multiple ducts from the nipple.  The fluid can vary from white to yellow to green to brown to blue-black.   Recommended treatment is to instruct the patient to avoid self-expression of the fluid.
 
Pathologic nipple discharge is a spontaneous occurrence usually seen from one breast and isolated to a single duct from the nipple.  Discharge from the nipple can vary from a clear to a bloody. If this occurs, the patient needs to undergo further evaluation including a physical and breast imaging. The most common cause of bloody nipple discharge is a ductal papilloma however breast cancer needs to be ruled out.
