ER+PR+HER2+breast cancer, stage 2b- lymph vascular invasion-what r stats/odds it's spread to other parts of the body?

Staging workup. If you know, you are a stage 2b, then I assume you have had surgery. If you were a stage 4, which is spread to other parts of the body, that would be known and dictate your treatment. A CT or PET scan can determine if there is spread to other areas of the body. Speak to your oncology team about your concerns so they can provide you with additional info. Good luck!!
