1- Is she itchy or licking the area?
Thank you for the pictures. Friend, the lesions are consistent with a superficial bacterial infection. What you can do is pick up over the counter in your local pharmacy (CVS) Hibiclens antibacterial soap. Wash area with this soap. Then, apply a topical antibiotic like neosporin or bacitracin. Do this 2 times a day for the next 10 days. If not significant or if the lesions begin to spread follow up with family veterinarian to start her on oral antibiotics.

Friend, without a biopsy I can not say ever 100% certainty that it is not cancer. But, given the history and appearance of the lesion it does resemble like a bacterial infection. Unlikely to be cancer.
