Study Notes
Biopsy Procedures
- A biopsy is a procedure that removes a sample of cells or tissue for examination.
- Cells/tissue are examined under a microscope to check for cancer.
- Biopsies help diagnose diseases and can be used as a treatment.
Needle Biopsy
- A needle biopsy uses a needle to remove tissue or cells from a lump or organ.
- Two types: fine needle and core needle biopsy.
- Fine needle: thin hollow needle removes a tissue sample.
- Core needle: thicker needle removes a core of tissue.
- Typically done in a doctor's office.
- Uses imaging (e.g., ultrasound or mammography).
- Often used as a quick, less invasive procedure.
Open Biopsy
- A surgical procedure that removes tissue by opening the skin.
- Surgical procedure to remove an entire lump.
- More complex procedure than a needle biopsy.
- May be necessary if entire lump is needed for testing.
Indications for Biopsy
- Diagnosing cancer.
- Determining if a lesion is cancerous or benign.
- Removing entire cancer (if possible) as treatment.
Contraindications for Biopsy
- Significant coagulopathy (a tendency to bleed).
- Some medications (e.g., aspirin, warfarin, clopidogrel) may not be stopped.
- Patient's overall health.
Cytology
- Specimens for cell culture or cytological analysis are obtained, sometimes using brushes, tubes, and washings.
Lump Detection
- A biopsy is often the first step in diagnosis and treatment when a lump is found.
- Can be a diagnostic procedure or a treatment.
Advantages of Needle Biopsy
- Simple procedure, no major surgery.
- Fast, only a few minutes to complete.
- Less painful than open procedures.
- Doesn't require a hospital stay.
- Relatively inexpensive.
- Quick results.
Disadvantages of Needle Biopsy
- Doesn't remove the entire lump.
- In some cases, an open biopsy could be necessary.
- A specialist may need to read the results.
Procedures (Punch, Shave, Incisional, Excisional)
- Punch biopsy: Removes a small cylindrical sample of skin or other tissue. Used for small lesions, possibly suspect melanoma.
- Shave biopsy: Removes a thin slice of tissue from a raised lesion. Useful for removing skin lesions.
- Incisional biopsy: Removes a portion of the lesion. Used for larger lesions which need partial removal.
- Excisional biopsy: Removes the entire lesion and some surrounding tissue. Used for complete tissue removal.
Specimen Processing Steps
- Specimens are typically fixed in formalin.
- Gross examination and sampling.
- Fixation, decalcification, dehydration.
- Clearing, infiltration.
- Staining and mounting.
- Microscopic examination (e.g., H&E staining, Immunofluorescence).
Additional Notes
- Informed consent is usually required.
- Coagulopathy is a condition that affects the ability of blood to clot, needing careful consideration before some procedures.
- Allergies to anesthetics should be reported and addressed before a procedure.
