Here's why:
* Uncontrolled Cell Growth: Cancer is characterized by abnormal, uncontrolled growth of cells. This happens when cells ignore the normal signals that regulate cell division and death.
* Mutations: These uncontrolled growth patterns are often caused by mutations in genes that control cell growth and division.
* Tumors: As these abnormal cells accumulate, they can form tumors, which can be benign (non-cancerous) or malignant (cancerous).
* Metastasis: Malignant tumors can spread to other parts of the body, a process called metastasis, making the cancer more difficult to treat.
It's important to remember that cancer is not a single disease, but rather a collection of many different diseases with a common feature: uncontrolled cell growth.
