What is the cause of malignant neoplasm?Causes of neoplastic disease In general, cancerous tumor growth is triggered by DNA mutations within your cells. Your DNA contains genes that tell cells how to operate, grow, and divide. When the DNA changes within your cells, they don’t function properly. This disconnection is what causes cells to become cancerous.
