Although biopsy is most often associated with cancer, it can also be used to check for other diseases, such as infections. A biopsy sample can be scraped, cut, collected with a needle, taken with a machine that punches out a tiny piece, or removed with the tiny tools in an endoscope.

In most cases, a biopsy is a simple outpatient procedure. Depending on the procedure, patients may need to stop taking certain medications beforehand, such as blood thinners. It is important for patients to tell doctors if they are pregnant, as certain biopsies require the use of x-rays to guide the needle to the right location. There is usually very little pain associated with a biopsy. Patients will have to wait a few days to hear the results.

During dermabrasion, a nurse or other healthcare professional holds the skin taut so that the doctor can apply gentle but constant pressure on the skin using the device. Depending on how much skin needs treatment, it may take a few minutes to over an hour to complete the surgery.

A waxy or moist dressing is placed on the skin at the end of the procedure. The treated area will be red and swollen for about two to three weeks. Itchiness and tingling will likely be present for some time. Although less common, enlarged pores, cold sores, rashes, and permanent skin discoloration may also occur. Normal activities may be resumed about two weeks following dermabrasion. However, swimming in chlorinated water and sports that involve the use of balls should be avoided for four to six weeks.
