Hi D.,
I agree that you should try not to worry too much. Because, I am sure you will worry until you find out the results. Last year I was told my mammogram showed a lump and that I should have an ultrasound. I also am a member of an HMO. The ultrasound did confirm the existence of a tumor near the chest wall.
Questions I wanted to know were the location of the tumor, its size, and whether or not you should have a biopsy. Although, they were pretty sure, after the ultrasound, it was not a cancerous lump, I along with my primary physician chose to have a core needle biopsy done. It is a type of biopsy in which a large hollow needle is inserted through the skin to the site of the abnormal growth to collect and remove a sample of cells for analysis. This procedure uses an automated needle, which obtains one sample of tissue at a time and is re-inserted several times. After the several passes of the needle, because of the size of the tumor, it was virtually obliterated. The result of the biopsy was that the tumor was not cancerous. They did follow up, six months later, with another mammogram, which again was clear. So, do ask questions and try not to worry too much.
I realize everyone is different. However, I did choose to do some research on the internet which helped to put my mind a little at ease and helped to prepare me for any potential news. If you choose to have a biopsy, it is best to take someone with you to that appointment as they did not even want me to carry my purse after the procedure. I hope all goes well for you. Take care.
