What is a soft tissue density nodule?

During my CT of my chest, they found a 9 mm soft tissue density nodule. Does it mean its cancer? I had papillary microcarcinoma of the thyroid March 27, 2009 and I am worried it might have spread to the breast.

A mammogram and ultrasound were done last night and won't get results for 48 to 72 hours.

Only a biopsy of some type could determine if the density is malignant. I'm sure your upcoming reports will clear this up somewhat and if not then depending on those reports a biopsy may be the next step. Thyroid cancer as a rule will (if at all) metastisize to the nearby lymph nodes first ... then possibly to other organs like the lungs or bone.  I wouldn't jump to any conclusions just yet; if that's possible.    Take care .....

Lump was found to be a simple cyst and they want to recheck it in 6 months. The thing that worried me was that I do have a lymph node up in the same place that was up when they found the thyroid cancer and I also have a mass on the right side of my trachea with pain. My Endo has told me to keep an eye on it and watch and see if it grows anymore.

That's good news about the cyst ..... the other issue of course is a seperate one unto itself. Often when a lymph node becomes enlarged it never goes back to a "normal" size but I'm confident that your Endocrinologist will keep an eye on things in that area.    Regards ....
