Study Notes

Biopsy Overview

A biopsy is a medical procedure to remove and examine tissue for disease diagnosis.
It combines the Greek words "bios" (life) and "opsis" (sight).
A biopsy involves removing a tissue sample and examining it under a microscope by a pathologist, a doctor specializing in bodily tissues and fluids.

Biopsy Types

Scrape biopsy: Removing surface cells, common in Pap smears.
Punch biopsy: Removing a tissue disk using a small round knife, often for skin cancer.
Needle biopsy: Using a needle to extract a sample. Can be a fine-needle aspiration biopsy (FNAB) or core biopsy (wider needle).
Stereotactic biopsy: Using 3D imaging to guide sample collection from abnormal areas (e.g., breast, brain).
Colposcopic biopsy: Using a colposcope (special telescope) to examine the cervix after an abnormal Pap smear.
Endoscopic biopsy: Using an endoscope to collect samples from internal areas like intestines, colon, or lungs.

Biopsy Uses

Diagnosing cancerous and non-cancerous diseases.
Determining if a growth is cancerous.
Diagnosing causes of stomach pain (inflammation, bacteria like Helicobacter pylori).
Identifying lung masses as cancerous or not.
Determining if breast tissue abnormalities are benign or cancerous.
Diagnosing various diseases, including cancerous and non-cancerous conditions.

Biopsy Analysis & Results

Pathologists examine tissue under a microscope.
They determine malignancy (cancerous) or benign (non-cancerous).
Assess cancer aggressiveness/stage (if malignant) to guide treatment.
Prepare a report with findings, sent to the ordering doctor.
Result time varies depending on complexity, from 12 days for simpler biopsies to longer for complex cases. Delays might be due to additional tests or second opinions.

Biopsy Preparation & Procedure

Preparation varies by biopsy type.
FNABs typically only require a consent form and gown change.
Some biopsies may require fasting.
Discussing medications/supplements is important.
Most biopsies are outpatient procedures.
More invasive procedures may require anesthesia and overnight stay.
Anesthesia type varies (from local for FNAB to general for surgical biopsies).
Pain is minimized by anesthesia; some procedures might have a sharp pinch, followed by potential soreness for a few days.

Biopsy Safety

Biopsies are generally safe with low risks of infection and bleeding.
Rare cases of excessive bleeding may need further procedures.
Early cancer detection through biopsy improves survival rates.
