Neil Shear, head of dermatology; and Dr. Frances Wright, a cancer surgeon who specializes in melanoma (and breast cancer) cases. First of all, both doctors say a biopsy cannot spread skin cancer regardless of whether the whole lesion is removed or not.

Are biopsies accurate?

In regard to determining exact diagnosis, fine-needle aspiration had a 33.3% accuracy and core biopsy had a 45.6% accuracy. With regard to eventual treatment, fine-needle aspiration was 38.6% accurate and core biopsy was 49.1% accurate.

Do bad biopsy results take longer?
