Biopsy for suspected malignant lesions pose a post-biopsy bleeding risk.
One of the techniques to control this situation is by giving prae-biopsy "bleed- reduction medication" and/or doing coagulation using electrical discharges("electrocoagulation").
Using laser as a technique to control bleedings might be an option,however we have to be aware of possible "rebleedings" due to the broken/abnormal walls of the neovascularisation of the tumor ("neoangiogenesis") or of the "feeding vessels".
Using cryo-techniques might be another possibility to counter bleeding with a special treatment for the biopsy specimen.
One should mention the possibility of reducing distant metastasis by this technique(by blood-born or lymph- vessels).
Tumor debulking by laser and/or cryosurgery may help conventional tumor surgery.(by "down- staging")
Endoscopic photo of this case of nasopharyngeal cancer biopsy was completed by argon beam coagulation to control post-biopsy bleeding.
