vävnadsundersökning

Vävnadsundersökning, also known as biopsy, is a medical procedure used to obtain a sample of tissue from the body for examination. This procedure is commonly performed to diagnose or investigate various conditions, including cancer, infections, and inflammatory diseases. The tissue sample is typically taken from a suspicious or abnormal area identified through imaging tests, physical examination, or other diagnostic methods.

There are several types of vävnadsundersökning, including:

1. Incisional biopsy: This involves making a small cut in the skin to remove a piece of tissue. It is commonly used for diagnosing skin conditions and certain types of cancer.

2. Excisional biopsy: Similar to an incisional biopsy, but the entire abnormal area is removed, leaving a small margin of normal tissue around it. This is often used for diagnosing breast cancer.

3. Punch biopsy: A small, cylindrical sample of tissue is removed using a specialized tool. This method is often used for diagnosing skin conditions and certain types of cancer.

4. Fine-needle aspiration (FNA): A thin needle is used to extract fluid or cells from a cyst, tumor, or other abnormal area. This method is often used for diagnosing thyroid conditions and certain types of cancer.

Vävnadsundersökning is typically performed in a clinical setting, such as a hospital or outpatient clinic, under local anesthesia. The procedure is usually quick and relatively painless, although some patients may experience discomfort or bruising at the biopsy site. After the procedure, the tissue sample is sent to a laboratory for analysis, and the results are used to guide further treatment or management of the condition.
