Breast cancer

Hi. I’m a 46 year old woman and a few weeks ago I had a growth on my areola which became infected. I was referred to the breast clinic and put on a course of antibiotics in the meantime which helped as it was sore and bleeding. At the breast clinic I had a mammogram followed by an ultrasound and a biopsy. They found a cortex thickened lymph node in the same breast measuring 4.2mm. I’m now awaiting results after they had a meeting yesterday. My next appointment is on the 30th. I’m exhausted and scared. Has anybody else been through this? Thankyou for reading.
