A skin biopsy is a procedure where a small sample of skin is removed for testing. This can help diagnose various skin conditions, including infections, skin disorders, and skin cancer. Here's what you can expect during a skin biopsy: First, your doctor will clean the area of skin where the biopsy will be taken. They will then numb the area with a local anesthetic, so you won't feel any pain during the procedure. There are different types of skin biopsies, including shave biopsy, punch biopsy, and excisional biopsy. The type of biopsy used will depend on the size and location of the skin lesion. During a shave biopsy, your doctor will use a small blade to shave off a thin layer of skin. In a punch biopsy, a circular tool is used to remove a deeper sample of skin. An excisional biopsy involves removing an entire lump or area of abnormal skin. After the sample is taken, your doctor may use stitches to close the wound, especially if a larger sample was removed. They will then cover the area with a bandage. The skin sample will be sent to a lab for analysis. You may experience some soreness or minor bleeding at the biopsy site, but this should go away within a few days. Your doctor will give you instructions on how to care for the biopsy site to prevent infection. You should avoid strenuous activities that could stretch the skin and delay healing. Results from the biopsy usually take a few days to a week. Your doctor will discuss the findings with you and talk about any further treatment if needed. Skin biopsies are generally safe, but like any medical procedure, there are some risks, including infection, bleeding, and scarring. If you notice any signs of infection, such as increased redness, swelling, or pus, contact your doctor immediately.
