Enlarged Lympnode

Patient: My boyfriend has a enlarged lympnode in his armpit. The emergency doctor did a ultrasound and said it is covered with blood vessels and doesn’t have any infection in it and the blood results came back fine.she wants him to see a primary doctor for a possible biopsy because he has lost 90 lbs since march and is always tired he is a landscaper and it gets very hot here where we live we thought that was the problem he occasionly has bad sweats during the night. We do not have insurance and Im worried it may be cancer he is 26 years old.
