My mammogram shows a benign lesion. Why/how is this there? Is it a precurser to cancer? I am 53 and my mom is a breast cancer survivor.

In brief: If it is

a benign lesion(BIRADS 2), it is not a precursor to cancer, and generally no follow up is necessary.
Benign breast lesions are common incidental findings, and include cysts, fibroadenomas, and lymph nodes, among other various things.

In brief: Lesion from hormones

The breast is a glandular organ, susceptible to the effect of exogenous hormones.
Lesions like fibroadenomas identified as having smooth margins with possible chunky and not microCa++ present. Benign lymph nodes and various cystic lesions are also seen which can be identified as benign. When questionable, needle aspiration or MRI of breast can be performed. Such lesions are not precancerous.

In brief: No.

Benign lesions are not pre-cancerous.
However as your mother had breast cancer, there will be an increased chance that you may develop it, therefore, have anything suspicious checked out immediately, and continue yearly mammograms, and breast exams by your GYN.

In brief: See a breast surgeon

If breast US shows fluid,aspiration has to be done under local anaesthesia If .
Repeat mammo shows anything biopsy must be done-preferably stereotaxic biopsy. Any genetic studies done ?

In brief: Benign breast lesion

There are many types of benign breast lesions.
Causes are not entirely clear, likely multi-factorial. Usually they are NOT precursors for breast cancer. However, certain types of benign lesions such as proliferative with atypia are associated with increased risk of subsequent breast cancer. Therefore, these high risk lesions should be monitored and sometime surgery is recommended.

Note that those lesions requiring follow up or surgery are histologic diagnoses following biopsy. These lesions are not diagnosed as benign on mammography. If they were seen on mammography, they would have been characterized as suspicious, which would prompt the biopsy. Lesions diagnosed as benign(BIRADS 2) on mammography do not require biopsy or short interval follow up.

In brief: Insufficient info

Imaging studies are usually not confirmatory in diagnosing breast lesions.
There are multiple type of lesions that are benign and not precursors to cancer, e.f., fibroadenoma, cystic disease, fat necrosis. It would be prudent to discuss the issue with your doctor who has more information about our health.

If the lesion was classified as benign(BIRADS 2) on mammography, the imaging study IS sufficient to categorize the lesion, and neither biopsy nor short interval follow up is necessary.

In brief: Need more info

Benign lesions in Breast are commonly found.
But it requires an experienced radiologist to make a declaration that the lesion seen is indeed benign. What made him say that it is benign? It usually requires a needle biopsy to be sure that something is benign, unless it is a Fibroadenoma or a cyst. Please find out if it is one of these entities. There is little risk of them becoming a cancer.

In brief: Benign

is a harmless growth without characteristics of cancer.
It would be logical for you to be sceened for the BRACA tumor marker ( blood anaysis ). Continue breast self examination and follow up.

In brief: Need evaluation and

monitoring of your benign lesion especially with your family history.
Some lesions could be precursor to malignancy most the time benign lesions like thickened breast tissue remain benign. Some times need tissue examination with image guided needle biopsy to assertion histological status. Follow your doctors advise

In brief: Probably not

The most common cause of benign lesions are fibrocystic breast changes which occur in 90% of women by age 40 and do not increase the risk of breast cancer.
Your mom's breast cancer does increase your risk especially if it was premenopausal but this finding does not necessarily increase it anymore. Continue your monthly breast self exams, annual mammograms, and annual exams by your doctor&exercise
