Recent bcc in neck

Hi everyone.

i have just had a bcc removed from neck on right side, awaiting further results. I have had chronic breast infection since September last year, now finally cleared with combination antibiotics (following 10day iv in hospital) they confirmed no cancer in breast, however the lump in neck started exactly same time as breast infection and I’ve picked up every infection since. My question is:

is there a chance the bcc could have spread and the fatigue, stiffness in neck and wheezing (been told its from the neck area as lungs are clear) could be cancer? I know we won’t know until the results from biopsy yet I’m really concerned as symptoms and infections aren’t easing

thanks
