Had shave biopsy today just because it was 'new' (less than 3 months?).
Hello,
Since you have a history of dysplasia, hence this spot needs to be examined and biopsied. Also keep an eye on it. If you notice changes in its color, height, size or shape, you should have a dermatologist evaluate it. You also should have it checked if it bleeds, oozes, itches, appear scaly, or become tender or painful. If it is malignant then the rate of progression of malignancy would depend on the type of skin cancer it is.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
