Considering this, what size are cancerous lymph nodes?

Lymph nodes measuring more than 1 cm in the short axis diameter are considered malignant. However, the size threshold does vary with anatomic site and underlying tumour type; e.g. in rectal cancer, lymph nodes larger than 5 mm are regarded as pathological.

Subsequently, question is, what is the normal size of retroperitoneal lymph nodes? Most authors are in agreement that lymph nodes with a diameter exceeding 20 mm are to be regarded as pathologically enlarged, and that those less than 10mm are normal.

Can ultrasound detect cancer in lymph nodes?

A lymph node ultrasound and biopsy is a way of checking the lymph nodes under the arm after breast cancer is diagnosed. Sometimes the cancer cells can spread into the nearby lymph nodes. Ultrasound scans use high frequency sound waves to create a picture of a part of the body. This turns the sound waves into a picture.
