FAQs About a Skin Biopsy
Why do I need a skin biopsy?
A doctor may perform a skin biopsy if the patient has skin symptoms such as a persistent rash, open sores, or an irregular mole or growth. The diagnosis of the correct skin condition makes treatment more effective.
How long will it take to get results from a skin biopsy?
Laboratory procedures vary based on the type of skin condition and skin biopsy performed. It often takes one to two weeks to get the results, but it can take longer. Discuss the wait time with the doctor.
Will I have a scar from a skin biopsy?
Skin biopsies generally cause a small scar, according to the Mayo Clinic. The size and severity of the scar depend on the type of biopsy and where the skin is removed. Biopsies on the neck or upper torso may be more prominent. The scar may be pink at first, then fade to white or brown over time.
Does a skin biopsy hurt?
Skin biopsies are usually performed using a local anesthetic administered by injection. A small pinch may be felt when the medication is injected. Some patients feel pressure during the procedure.
What skin conditions can a biopsy detect?
A skin biopsy is used to detect skin cancers, such as melanoma or basal cell carcinoma. A biopsy can also identify eczema, psoriasis, and infections. If the results are normal, it means no skin disease or skin cancer was found.
Are there risks associated with a skin biopsy?
The biopsy site may be sore or bruised for a few days following the biopsy. There may be some bleeding at the wound site. If the symptoms prolong for more than a few days, talk to the health care provider.
