Warning Signs of Cancer
Cancer is a group of diseases that manifest themselves in a variety of ways. As cancer grows, it will begin to put pressure on certain nerves, blood vessels, and organs. As a result of this constant pressure, signs and symptoms will begin to present themselves. How the signs and symptoms present themselves will depend on many factors, such as how big the cancerous tissue is, where it is located, and how much the organs and tissues are affected.
For example, if the cancer is located in the brain, even the smallest of tumors can cause severe symptoms. On the other hand, if cancer starts in the pancreas, symptoms won’t present themselves until after the cancer has grown very large and spread to other parts of the body, at which point cancer is said to have metastasized.
