Final answer:
Wilm's tumor represents a malignant tumor, a form of cancer characterized by unregulated cell growth that invades other tissues and may lead to metastasis.
Step-by-step explanation:
Wilm's tumor is an example of a malignant neoplasm or malignant tumor, which is also known as cancer. It's an abnormal proliferation of cells that are genetically altered, often forming a mass or lump known as a tumor. This type of tumor does not stop growing on its own, can invade other tissues, and may form metastases, which are secondary malignant growths at a distance from the primary site of cancer.
Cancer arises when mutations within a single cell lead to uncontrolled cell division, resulting in a mass of cells cloned from the original mutated one. If a tumor is benign, it remains localized and does not invade neighboring tissue, which alleviates it from advancing into a life-threatening condition. However, when discussing Wilm's tumor, it is invasive, which means it has the potential to spread to other parts of the body and harm normal functions of the affected tissues.
