Detailed explanation-1: -Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Detailed explanation-2: -With increasing cell growth, cancer cells spread or infiltrate to involve other organs, displacing normal tissue and severely depleting nutrient and metabolic resources, which results in death either from cancer cachexia or from mechanical disruption of normal organ function.

Detailed explanation-3: -Tumor Metastasis. The major cause of cancer is due to uncontrolled cell division which forms a cell mass called Tumor. This may occur due to failure in cell cycle regulation. These tumors or cell masses reach other organs through a multistep process termed metastasis.

Detailed explanation-4: -cancer, the uncontrolled growth of cells, often results in a tumor, or mass of abnormal cells. Some cancerous tumors consist of many cells that are much smaller than normal.

Detailed explanation-5: -Cancer is basically a disease of uncontrolled cell division.
