Study Notes
Biopsy: Procedure and Analysis
- A biopsy is a medical procedure where a tissue sample is removed and examined by a pathologist to diagnose diseases. The word comes from Greek roots meaning "to view life".
- Different biopsy types exist based on tissue location:
- Scrape biopsy: Surface cells are removed (e.g., Pap smears).
- Punch biopsy: A round knife removes a tissue disk (skin cancer).
- Needle biopsy: A needle extracts a sample (core or fine-needle aspiration).
- Stereotactic biopsy: 3D imaging guides sample collection from located abnormalities (breast, brain).
- Colposcopic biopsy: A colposcope examines the cervix after abnormal Pap smears.
- Endoscopic biopsy: An endoscope collects samples from internal areas (intestines, colon, lungs).
Biopsy Uses
- Biopsies diagnose cancerous and non-cancerous diseases.
- Examples:
- Cancer: Determining if growth is cancerous.
- Gastric: Diagnosing stomach pain causes (inflammation, bacteria like Helicobacter pylori).
- Lung: Identifying lung masses as cancerous or not.
- Breast: Determining if breast abnormalities are benign or cancerous.
Biopsy Analysis and Results
- A pathologist examines the tissue sample under a microscope.
- Determines if the sample is malignant (cancerous) or benign (non-cancerous).
- Assesses cancer aggressiveness/stage (if malignant).
- Prepares a report and sends it to the ordering doctor.
- Result time varies depending on complexity; simple results in 12 days or less, complex might take longer.
Biopsy Procedure Expectations
- Preparation depends on the biopsy type.
- Some biopsies may require fasting.
- Discuss medication/supplement use with the doctor.
- Most are outpatient procedures; some may require anesthesia and overnight stay.
- Anesthesia type varies (e.g., local for FNAB, general for surgical biopsies).
- Pain is minimized by anesthesia; potential soreness for a few days.
Biopsy Safety
- Generally safe, with low risks of infection and bleeding.
- Rare cases of excessive bleeding.
- Early cancer detection through biopsy improves survival rates.
