As a cancer grows, it can begin to push on nearby organs, blood vessels, and nerves. This pressure causes some of the signs and symptoms of cancer.

This may be because cancer cells use up much of the body’s energy supply, or they may release substances that change the way the body makes energy from food. Or the cancer may cause the immune system to react in ways that produce these signs and symptoms.( www.cancer.org) Cancer is the second leading cause of death among adults over the age of 45.HGD Chapter 15, p.400
