This is just my opinion. It's not a medical advice. Consult your physicians for medical advices.
My own research and conclusion has led me to believe that biopsy while being promoted as safe can be quite harmful and could be the beginning of the demise of cancer patients. The evidence of the harm of breast biopsy is removed because invariably, they always cut off the breasts. You need to study and talk to another group of people who do get biopsied, the hepatitis people. In that case, the evidence stays because they can't get rid of the liver. I have heard of complaints that liver biopsy is the cause of cirrhosis from hepatitis people. It's the injury from the biopsy that started the whole chain of negative events.
From the book, Keep Your Breasts! by Susan Moss
Later, cancer specialist,Dr. James Privitera explained to me the theory that a hard lump in the breast is the body's way of encapsulating cancer cells with a protein coating, and that cutting or poking into the breast opened the capsule, allowing malignant cells to spread into the blood stream.
Did you know that there are many studies that show that surgical removal of the tumor can cause metastases? There is also scientific evidence that the body reacts by not only creating more cancer cells but by creating cancer stem cells, which are very difficult to kill.
Here is Lloyd Wright who has worked with thousands of hepatitis patients. Listen carefully @3:43, where he said all the liver cancer patients who got biopsied, died. Biopsy is not harmless as we were led to believe.
Listen to Sal discussed biopsy and cancer @23:45 - 30:00
There are other ways to assess cancer such as blood test, urine test and thermography. But the medical establishment is very controlled and regulated. A positive biopsy means 2-300 hundred thousand dollars that insurance will pay for the course of the treatment. Patients will also go along too because that is what the insurance will pay. The medical system is set up to take that money, but the success of conventional breast cancer treatments is dismal. Biopsy results will be used as the dawn of the "Shock and Awe" campaign. They will shock you with the big C word and awe you with the treatments they have in store for you. You will be rushed to surgery. They will announce that, "We got it all." But cutting into cancer releases cancer stem cells that will come back with a vengeance within a year or two. But of course, they have expensive chemo for that which don't work. Even before that, the innocent biopsy, will release cancer stem cells into the blood stream if cancer was present. If you had no cancer before, the injury can cause the cancer to grow there. It's a no win situation. I think biopsy is barbaric, extremely harmful and shouldn't be used at all. For breast, try Thermography. For liver, Fibroscan. I wouldn't do a biopsy no matter what organ.
Fibroscan for liver
Urine test for cancer
