Here's why:
* Uncontrolled cell division: Cancer cells ignore the normal signals that regulate cell growth and division. They continue to multiply and form tumors.
* Invasiveness: Cancer cells can invade surrounding tissues and spread to other parts of the body (metastasis).
* Variety of forms: Cancer can arise from almost any cell type in the body, leading to a wide range of types and symptoms.
Important to note: While cancer is defined by uncontrolled cell division, it's a complex disease with many contributing factors, including genetics, lifestyle, and environmental exposures.
