Myth: A needle biopsy can disturb cancer cells, causing them to travel to other parts of the body.

Truth: For most types of cancer, there's no conclusive evidence that needle biopsy — a procedure used to diagnose many types of cancer — causes cancer cells to spread.

There are exceptions, though, of which doctors and surgeons are aware. For instance, needle biopsy usually isn't used in diagnosing testicular cancer. Instead, if a doctor suspects testicular cancer, the testicle is removed.

Myth: Exposing a tumor to air during surgery causes cancer to spread.

Truth: Surgery can't cause cancer to spread. Don't delay or refuse treatment because of this myth. Surgically removing cancer is often the first and most important treatment.

Some people may believe this myth because they feel worse during recovery than they did before surgery. And if your surgeon discovers during surgery that your cancer is more advanced than first thought, you may believe the surgery caused more extensive cancer. But there is no evidence to support this.
