I went to the breast clinic nearly 3 weeks ago to investigate a lump. They did a mammogram, ultrasound and biopsy. Afterwards the doctor said it could be any of a number of things (including cancer) but they won't know until biopsy results come back.

Tiday I received a summary letter from the doctor insaw (I don't know why it took so long to get here) in the letter it describes the breast lump but also says a biopsy was taken from a slightly enlarged lymph node. What does this mean? No one told me I had an enlarged lymph node they just said they would take biopsy from breast and arm pit.

Is an enlarged lymph node bad?

Really worried now ...
