I found breast lump mammogram shows fibroadenoma but i read in the report axillary lymphnodes mildly enlarged and mostly reactive what does this mean ?

Lymph nodes: Can enlarge in response (therefore "reactive") to infection or inflammation. Or it can become enlarged with malignancy, such as lymphoma or metastatic cancer. I don't think findings on your mammogram are alarming. Ask your doctor to make sure.

Don't worry: At 19 it is most likely a benign fibroadenoma , so are reactive lymph nodes frequently seen in young woman, best options to take it out , or get a needle biopsy to establish diagnosis , then if it is fibroadenoma could be safely observed.

Swollen glands: The lymph nodes are cell destructive centers and respond to areas of inflammation and cellular mobilization to fight off a discerned problem. Your body's defense system has many types of white blood cells that when their job is completed are destroyed in the lymph nodes.

Lymph nodes: Are commonly seen on mammograms. It sounds like it is nothing to worry about. Discuss it with your doctor if you are worried.
