Suspicious spots or moles can be tested with biopsy under local anaesthetic and specimen sent to pathology for testing.
A few lesions need to be removed completely by excision instead of taking a biopsy. A biopsy takes a sample of the lesion to be examined by the pathologist to diagnose skin cancer.
The procedure takes a few minutes and is done under local anaesthetic, where a small amount of anaesthetic is injected into the lesion to make it numb. Although you may feel a slight sting with the injection for the local anaesthetic, you will not feel any pain with the biopsy itself.
