Hello i had a cat scan done on pelvic and abdoan done today the are looking at lymph nodes what does lyphoma orlung cancer look like on cat scan?

A mass.: Lymph nodes are scattered throughout the body and are normal structures. They should not be larger than 1 cm in diameter. Lymph nodes that contain metastatic disease, or lymph nodes containing lymphoma, are detected on a cat scan based on size over 1 cm. A pet/ct has an additional criterion, increased glucose uptake, to suggest cancer.

Most lung cancer: Presents as a shadow on a chest x-ray, or a nodule (0.5 to 3 inches in size) on a ct. Many patients have symptoms of coughing or spitting up blood which leads to the ct. Lymphoma will have enlarged lymph nodes, sometimes up to 5 or 6 inches (normal is less than 0.5 inch).
