Question:

I had a mammogram which indicated 2 cysts in the left breast. My doctor told me they were noncancerous and not to worry. He did not perform any biopsies, just reviewed the mammogram.

My question is since I have had a history of premalignancies (ovarian – in mouth, and on skin) is this a wise decision not to biopsy. Just what is a pre-malignancy. Is it a cause for concern.

Answer:

Pre-malignancy or pre cancer is a term to describe changes in the cells. The cells look different than the normal cells and may be too many or extra cells (hyperplasia) in a certain area. Another characteristic of pre cancer is that it has not invaded surrounding tissue. Pre cancer needs to be followed by the physician on a regular schedule.

A cyst is not pre cancer. It is a fluid-filled sac that feels smooth, movable and possibly squishy with examination if it is close to the skin. If it is deep in the breast tissue, it may feel like a hard lump. A cyst is seen in the mammogram as a area of density. Then it is necessary to do an ultrasound to determine if it really is a cyst or a solid lump. If the ultrasound confirms that the area in the breast is a cyst, then a biopsy is not necessary. If it is not a cyst, then a biopsy is necessary to tell what it is. Sometimes cysts cause pain. Aspirating the cyst relieves the pain. I hope this answer helps you understand your condition and any further questions you may have for your physician. Thank you for writing.
