What condition is characterized by uncontrolled growth of abnormal cells in the body?

The condition characterized by uncontrolled growth of abnormal cells in the body is cancer. Cancer occurs when the regulatory mechanisms that control cell division fail, leading to the proliferation of cells that do not die off as they should. This unchecked growth can form a mass known as a tumor, which can invade nearby tissues and potentially spread to other parts of the body through the bloodstream or lymphatic system.

Understanding cancer involves recognizing its complex nature, where genetic mutations and environmental factors contribute to the disease process. Unlike benign tumors, whose cells grow uncontrollably but typically do not spread to other areas, cancerous cells can metastasize, making it a more serious and often life-threatening condition.

In contrast, inflammation refers to the body’s natural response to injury or infection, and while it can be associated with cancer, it does not represent uncontrolled cell growth. A benign tumor, although it consists of abnormal cell growth, does not exhibit the same invasive properties or aggressive growth patterns as cancer. A cyst is a fluid-filled sac that can arise from various conditions and is not defined by abnormal cell multiplication as cancer is.
