Does Dimpling On Breast Indicate Breast Cancer?
you need to be evaluated
Detailed Answer:
It is not very clear but I understand that you had a breast cancer on the LEFT side 12 years ago. Again, unclear but it appears that you have had a breast conservation surgery.
At the outset we have to understand that this area is not 'virgin' meaning it is an area which has undergone surgery and radiation. Hence, any finding like dimpling or mammographic findings may be difficult to interpret.
Having understood that, any alteration in findings like dimpling in your case needs to be evaluated. It would be premature and wrong to attribute it to any pathology before evaluation; more so since it is a treated area.
One possibility is that there could be a recurrence. However, this needs to be confirmed only by your surgeon with tests. Another possibility is that it could be post treatment changes which could confound the findings.
Instead of presuming things causing unnecessary anxiety, it would be prudent to get full evaluation. Since it is 12 years post therapy, the chances of recurrence would be less but not nil. That should give you some confidence for proceeding with further tests.
