One of the biggest concerns among the public regarding biopsy procedures is the fear that if the needle touches the tumor tissue, cancerous cells will spread (seed) to other organs. This belief is completely unscientific and causes patients to delay vital diagnostic steps.
Why is a Biopsy Safe?
Prostate or kidney biopsy techniques applied in modern urology use needles passed through special protective sheaths (coaxial systems). This prevents the needle from contacting surrounding healthy tissues when withdrawn after taking a sample.
Dangers of Delaying Diagnosis
In medical studies, there is no scientific evidence that standard biopsy needle procedures cause cancer to spread in urological cancers. Early diagnosis saves lives.
