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.

Debridement can be performed either surgically or nonsurgically; some methods are less invasive than others. Doctors select the appropriate debridement technique by considering the location, cause, and size of a patient's wound and may also weigh the patient's overall wellbeing, age, and risk of infection.

Surgical debridement is performed by cutting away dead, infected, and hyperkeratotic skin with a surgical scalpel. For deep wounds that tear away the skin and go into the muscle, skin from another region of a patient's body may be grafted onto the wound, which may then be periodically assessed and rebandaged until fully healed.

Non-surgical debridement is achieved with water or a dissolvent gel. Water softens the damaged skin and affected tissue, allowing doctors to remove it with wet-to-dry dressing. When wet tissue dries, it adheres to the dry dressing or bandage and comes off when the dressing is pulled away. In contrast, dissolvent gel deconstructs tissue, which can be cleaned off of the wound. Nonsurgical debridement is less invasive than surgical techniques; however, it can entail repeat treatments, slowing wound recovery.

While the prospect of stripping away skin may seem jarring, debridement can be critical to the treatment and healing of wounds which cannot not heal independently.

Mild sores may heal on their own when pressure on the affected area is reduced. This can be accomplished by simply repositioning the body every hour. If the sores are painful or infected, medications such as pain relievers and antibiotics may be prescribed. Cleaning the wound and changing dressings regularly also help the healing process. Severe pressure ulcers, on the other hand, may require surgery, which involves removal of any damaged, infected, or dead tissue and closing the wound. Wound closure can be achieved either by stitching the skin edges together or by using a flap of the patient's own tissue.

If a patient needs to have pressure ulcer surgery, they will likely be on bedrest for a few weeks to allow the wound to heal completely. The patient and their family members will be given instructions on positioning and transfer techniques to help keep pressure off the wound. When the doctor thinks the patient is ready, he or she will give the patient special exercises to help them regain their range of motion. To prevent the recurrence of ulcers, patients or their caregivers should be diligent about changing positions regularly, observing for early signs of new pressure sores, and replacing any worn-out mattresses or cushions.
