Here's why:
* Cancer is a group of diseases characterized by abnormal cell growth and division. This uncontrolled growth leads to the formation of tumors, which can invade surrounding tissues and spread to other parts of the body (metastasis).
* Normal cells have a complex system of regulation that controls their growth and division. This system can be disrupted by various factors like mutations, environmental toxins, or genetic predispositions, leading to uncontrolled growth.
It's important to remember that cancer is not a single disease, but rather a broad term encompassing many different types, each with its own characteristics and causes.
