Hi thanks for your question.
Relax the multiple scar which your having, secondary to recurrent boils
cannot be cancer.
These could be due to either inadequate treatment of the infection,poor hygeine and or due to high blood glucose
Get your blood glucose level checked and consult a nearby physician to know exactly what is the cause of recurrent boil and who will also treat your infection and pain.
Boils will cause pain in and around the surrounding structure.Hope this answers your question.
