What this result actually means
Perineural invasion means prostate-cancer cells are seen tracking around or along a nerve within the biopsy specimen. Its significance depends on the rest of the pathology and clinical stage.
One pathology feature should not be allowed to impersonate the entire risk model.

vigamaxx.comFrequently asked questions
Does this result diagnose prostate cancer by itself?
No. MRI, PSA, DRE and most biopsy-risk markers must be interpreted in context. Tissue pathology is what establishes a prostate-cancer diagnosis.
Can a negative MRI rule out clinically significant cancer?
No. It lowers risk but does not reduce it to zero.
Why does PSA density matter with MRI?
PSA density adds prostate-volume context and can refine risk when MRI is negative or indeterminate.
Can a negative biopsy miss cancer?
Yes. Sampling error is possible, which is why persistent MRI or PSA concern can justify review or repeat biopsy.
What is the difference between targeted and systematic biopsy?
Targeted biopsy samples MRI-visible lesions; systematic biopsy samples predefined regions across the gland.
Does biopsy route matter?
Yes. Transperineal and transrectal routes differ in infection risk, anesthesia and access characteristics.
Should I stop blood thinners before biopsy?
Do not stop prescription blood thinners on your own. The biopsy team and prescribing clinician should coordinate any changes.
Are antibiotics always needed for prostate biopsy?
The plan depends on biopsy route, local protocol and patient risk. Follow the biopsy center's instructions.
What should I ask when MRI and biopsy disagree?
Ask whether the target was sampled, whether MRI or pathology should be re-reviewed and whether repeat targeted sampling is justified.
Can a supplement change PI-RADS or biopsy pathology?
No supplement should be presented as a way to reverse an MRI category or pathology diagnosis.
When is repeat biopsy considered?
When residual risk remains meaningful because of PSA behavior, MRI evolution, pathology uncertainty or concern about prior sampling quality.
What records should I bring to a second opinion?
Bring MRI images and report, pathology report and slides if available, PSA history, prostate volume, prior biopsy map and medication list.
