  Mechanical force is tightly connected to human health status, and the
occurrence of disease can generally be ascribed to certain loss of force
balance. However, the role of mechanical approaches in tumor therapy is largely
neglected, while the currently available cancer prevention and treatment
methods are generally either expensive or just cause too much side effect. In
this article, we present a systematic interpretation on a promising strategy
which was termed here as Mechanical Therapy for the first time based on the
fact that mechanical force closely accompanies the whole life (growth and
death) of a cell, and plays a crucial role in biological functions. In order to
mold the mechanical force as a practical tool for cancer therapy, we expound
the effects of the mechanical force related to the tumors from molecule to
tissue level and evaluate its feasibility for treatment purpose. It can be
conceived that given enough investigations, the mechanical therapy may generate
big potential to open new windows for cancer prevention, relieving or even
destroying if well administrated. As an easy going and convenient method, a
systematic and thorough study of mechanical therapy may clarify more options
for future clinical practices. Besides, when patients encounter various forces
in daily life, they can at least identify the good or bad forces for a better
and healthy life style based on the mechanisms thus disclosed.
