Cancer is due to errors in the mode of living. ~ Duncan Bulkley
Cancer is an umbrella term for diseases characterized by uncontrolled cell growth. Cancer essentially emanates from environmental stimulus, though genetic expression tilts the risk for the disease.
Several epigenetic alterations characterize cancer, including lowering histone levels, which help activate the growth and ensure the survival of cancer cells. Cancer is a product of defective gene regulation, though the progression of cancer often has genetic repercussions as well.
