The term 'abnormal genetic material' in the context of cancer specifically refers to altered genes that can lead to uncontrolled cell growth. In cancer, mutations or changes in the genetic material can cause cells to bypass the normal regulatory mechanisms that control cell division and growth. These altered genes may result from factors such as environmental influences, lifestyle choices, or random errors in DNA replication.

When these genes become dysregulated, they can lead to the formation of tumors and the spread of cancer. This is in stark contrast to normal functional genes and those that regulate healthy cell division, which work to maintain proper growth and division of cells. Similarly, gene mutations that have no impact would not be classified as 'abnormal' since they do not change the normal functioning of the cell. Thus, the alteration of genes that results in disregulated growth is what characterizes cancer-related genetic abnormalities.
