What do all types of cancer have in common?

Uncontrolled Cell Growth

Cancer is characterized by the uncontrolled growth and division of abnormal cells in the body. These cells can form tumors, which can interfere with the function of organs and tissues and can spread to other parts of the body.

Genetic Changes

Cancer cells have genetic changes that allow them to grow and divide uncontrollably. These changes can occur in genes that control cell growth, cell death, and DNA repair.

Formation of Blood Vessels

Cancer cells often stimulate the growth of new blood vessels, which supply the tumor with oxygen and nutrients and help it to grow and spread.

Invasion of Surrounding Tissues

Cancer cells can invade and destroy surrounding tissues, including healthy cells. This can lead to pain, bleeding, and organ dysfunction.

Metastasis

Cancer cells can spread to other parts of the body through the blood or lymphatic system. This process is called metastasis and is the most common cause of death in cancer patients.

Avoidance of the Immune System

Cancer cells can avoid detection and destruction by the immune system. This allows them to grow and spread unchecked.
