Can a ct chest scan show if you have a tumor or any lumps, mass large lymphnodes around the breast area ? if the test was ment to look at the lungs ?

Yes, but: CT chest will show tumors or lymph nodes in the portions of the breasts imaged on the scan. Oftentimes, the upper portions of the breasts are not included in CT's of the chest. If the breasts are very large, sometimes the anterior (front) portion of the breast also may not be imaged. I hope this helps.

Usually yes: A CT of the chest frequently can reveal lymph nodes or other masses around the breast region. The same holds true of a 3D mammogram which can reveal nodal lesions in the armpit area or other masses in the region of the breast such as various sarcomas that can arise there post radiation therapy or even nodes in the supraclavicular. Only CT will show internal mammary nodes.

CT chest can: definitely demonstrate abnormal lymph nodes in the axilla and other regions of the chest. It can demonstrate masses throughout the chest area. It can occasionally pick up a breast cancer, but is limited in this respect by relatively low soft tissue contrast resolution, and spatial resolution significantly inferior to mammography.
