lenyomatás

Lenyomatás, also known as biopsy, is a medical procedure used to obtain a sample of tissue from the body for examination under a microscope. This procedure is essential for diagnosing various conditions, including cancer, infections, and other diseases. There are several types of lenyomatás, including:

1. Incisional biopsy: This involves making a small cut in the skin to remove a sample 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 tissue is removed, along with a margin of normal tissue. This is often used for diagnosing breast cancer and other conditions where complete removal of the lesion is necessary.

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 lesion. This procedure is commonly used for diagnosing thyroid nodules, breast lumps, and other conditions.

5. Core needle biopsy: A hollow needle is used to extract a small sample of tissue. This method is often used for diagnosing bone, liver, and other internal conditions.

Lenyomatás is typically performed under local anesthesia and is generally considered a safe and effective diagnostic tool. However, like any medical procedure, it carries some risks, including infection, bleeding, and scarring. It is important to discuss the potential benefits and risks of lenyomatás with a healthcare provider before undergoing the procedure.
