Normal cells become cancerous when the signaling pathways dictating cell cycle and death go awry. These processes involve a number of genes and proteins and can vary among tissues and organs. Cell transformation can be the result of genetic mutations, cell stress, or viruses. These components make cancer a very complex disease to prevent or cure. Many potential treatments and cures are being investigated for the myriad causes of cancer, including cancer vaccines, enzyme suppression, gene therapy, and the prevention and monitoring of drug resistance. Get a look at cancer cell formation and possible cures.
