@justme129 The PNI sounds frightening but as has already been explained by @topf, it is not an indication of more serious disease.
It is, however, indicative of the lateral spread of the abnormal tissue - outward toward the periphery. So if this turns into 3+4 or 4+3 (like mine) over time, it will have a greater chance of escaping the gland.
You’re good right now, but that second opinion and further testing is all important.
