7. Surgical Procedures Can Cause Cancer to Spread
While there is a small theoretical possibility that haphazard procedures could transfer cells to other areas of the body, there is no reason to worry about the spread of cancer during an operation on a tumor.

However, in some cases, the surgical team will find that the cancer has spread farther than they had imagined, and so a straightforward operation will not be enough.

Herbal medicine has much to offer people who have cancer, or who have had cancer in the past and want to ensure that they remain cancer free.
