Change on my aerola since visiting the breast clinic. Should I be worried? I go back on 2nd Feb for a follow up appointment

I recently attended a one stop clinic and was given the okay after ultrasound and mammogram although they said I have lump which is tissue muscle.  The next day I was asked to go back in 2weeks for follow-up appointment which is the 2nd Feb tonight I think one side of my aerola is indented. Should I worry
