If a lymph node is round with a well defined border and no fatty center is it always malignant?

In brief: No

What you describe sounds like an ultrasound report of a lymph node.
The only way to know for sure that a lymph node is malignant is to biopsy it (take a small sample of it.).

Imaging can give size measurements (only ~50% correlative to malignancy) and architecture information but only sampling will confirm metastatic involvement. Ultrasound guided FNA (fine needle aspiration) is a fairly quick and simple procedure in the skilled hands of a breast surgeon.

The only way to tell if a lymph node is malignant is to biopsy it (take it out and look at it under the microscope).

In brief: Imaging

Usually if the doctor has a suspicion that the lymph node may be abnormal (bigger than usual, hard, several of them) they will obtain a ct of the area and then consider a biopsy.
A biopsy where a piece of the lymph node or full removal of the lymph node gives the most information. Sometimes a very fine needle is put into the lymph node but that may not reveal the overall problem.
