Does cancer spread after biopsy?

Doctors and researchers have noted that biopsy of a tumor can cause seeding, or spread of cancer cells along the path of the needle track at the biopsy site. Author and health researcher Karl Loren has documented 73 cases of seeding from biopsies causing metastasis on his website, KarlLoren.com.

Most people assume their doctor will call them if they get a bad test result. But new research shows that doctors frequently fail to inform patients about abnormal test results.

What if the biopsy is positive?

Another important factor is whether there are cancer cells at the margins, or edges, of the biopsy sample. A “positive” or “involved” margin means there are cancer cells in the margin. This means that it is likely that cancerous cells are still in the body. Lymph nodes.

How often is a biopsy wrong?

One study looking at nearly 1,000 core needle biopsies found a false negative result rate of 2.2%. That’s just over 2 out of 100 biopsies. Sensitivity and specificity are two terms you may hear when talking about testing accuracy, including screening tests.

Is negative good or bad?

A negative test result isn’t always bad news. It means that the lab didn’t find whatever you were tested for. For instance, a negative result for strep throat means that the lab didn’t find any strep bacteria in the sample, so you probably don’t have it.
