Biopsy always detects a part of the cancer and hence it is always little more actually in real time.But it is still considered very early prostate cancer.So early that you fall into low risk group in whom this cancer may never grow or progress.
There is new treatment strategy known as active surveillance for such group.Prostate cancer is followed regularly every six months with PSA,biopsy and rectal examination & at any signs of progression of cancer, treatment is started.It is found that treatment given at a later date when the cancer shows signs of growing has similar results as when given at a earlier date when the cancer was first detected.
This is also called delayed active treatment.The main aim is to find those patients in whom this cancer will never progress so as to threaten his life span.In such patients we can avoid the side effects of the treatment or rather over treatment.
Disadvantage of this method is that regular follow up is required along with regular biopsies.Also anxiety issues can be there knowing that we are living with a cancer inside us.
So the alternative is getting the prostate gland removed which is the gold standard treatment for such cancers.
The most preferred way is robotic prostatectomy.Excellent cancer control as well as pain control is achieved by this method.Apex can be well excised and is not a problem.
You need to talk to your doctor regarding these issues.Bone scan will rarely be positive in such early cancer and low PSA.
I hope this helps you take a decision.
