What is the difference between neoplasm and malignancy?
Benign neoplasms do not grow aggressively, do not invade the surrounding body tissues, and do not spread throughout the body. Malignant neoplasms, on the other hand, tend to grow rapidly, invade the tissues around them, and spread, or metastasize (me-TAS-ta-size), to other parts of the body.

What causes 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.

The initial draft hierarchy organizes the neoplasm core set under three main headings (malignant, benign, and uncertain/mixed), with limited cross-listing. Several simplified hierarchies may well be needed; user input will be important in deciding on the most useful organization and scope for these.
