The Dutch word “gewas” can refer to both a crop and a tumor. In the context of agriculture, a gewas is a plant that is cultivated for its food, fiber, or other products. Some common gewassen include maize, wheat, rice, potatoes, and soybeans. In the context of medicine, a gewas is an abnormal growth of tissue that can be benign or malignant. Benign gewassen are typically harmless and do not spread, while malignant gewassen, also known as cancers, can invade and destroy surrounding tissue and spread to other parts of the body.
