Lump in armpit and breast

Hi guys

im new to this forum but just wanted to see if anyone had the same experience as me. Found a lump in armpit this morning, bean shaped. Went to doctors as armpit was also swollen, dr did examination and said it was a swollen lymph node, she then carried out a breast examination and found lumps in the breast next to the swollen lymph node. I'm worrying sick as she said I need urgent bloods and scans and wrote "urgent" on the forms, am I worrying for nothing or could it be ok?? She did say luckily enough she can only feel 1 swollen node in armpit and none in collarbone region.
