Web(4) Cancer cells often have unusual numbers of chromosomes or mutations in chromosomes. Aging, exposure to toxins (like components of tobacco tar), mutagens (like ultraviolet light) all cause mutations in genes and cancer; but normal errors in DNA replication can lead transformation of the cell if they occur in a crucial gene. WebGenes and Cancer Cancer begins when some of the genes in a cell become abnormal, causing the cell to grow and divide out of control.
