What is the treatment?
A biopsy is a simple operation where a small piece of tissue is removed from an area. This can be looked at closely under a microscope.
There are two types of biopsy: An excisional biopsy removes the whole area. This is usually carried out for small lumps or swellings. Further treatment may not be necessary.
An incisional biopsy involves removing a small piece of the abnormal area. This is carried out to confirm what something is. Then we can decide on the best treatment.
Most biopsies are carried out with local anaesthetic (a numbing injection into the area). The injection takes a couple of minutes to work. The biopsy should be painless.
