Skin biopsy: This really depends on what is being biopsied. For a "nodule" or "bump," to rule out cancer, a biopsy is usually likely to give a very accurate diagnosis, although some early forms of cancer can be difficult. Biopsies of "rashes" are more tricky. Sometimes the histology is classical, and a very specific diagnosis can be made. But sometimes the biopsy has a non-specific appearance.

Is skin biopsy a very common procedure?

Yes: Skin biopsies are routinely performed by dermatologists and primary care doctors on a regular basis. It is one of the most commonly performed procedures in a dermatologists office. If a doctor recommends a biopsy, you should always be given a reason for it. A second opinion can be requested prior to allowing a biopsy if you feel it is unnecessary.

2-3 weeks: If the biopsy was closed with a suture, the suture comes out in a week, and it takes another week to heal completely, except perhaps for a bit of redness at the site. Large biopsies, and biopsies in high-movement areas, might take a little longer.

It : It depends on how complex the lesion is and whether you are having mohs surgery done. Mohs surgery takes longer because small sections of the area are removed and analyzed under a microscope to determine if the lesion was completely removed. Because the mohs surgery is more conservative it will take more steps and a longer time. Additionally, the time of surgery is also affected by how long it takes to close the resulting defect.
