When abnormal mutations occur in a cells DNA, the cell will normally die. However, the cells sometimes continue to divide at an out of control rate forming clumps of cells. These clumps of cells grow into a mass of tissue called tumors. Tumors are either malignant or benign. Malignant tumors are cancerous. The out-of-control, mutated cells continue to divide as they invade and damage tissue and organs. Cancer cells can easily break away from the tumor and enter into the lymphatic system or the bloodstream, this allows the cells to form new tumors in other organs or other parts of the body.
Benign tumors are non-cancerous because the cells remain normal and do not pose a health risk.
Toxic-atoms known as free radicals can cause Injury to cells and to their DNA molecules.
Free radicals attack us in pollutants such as chemicals, poor diet, cigarette smoke, bad fats, processed foods, genetically altered foods, nitrates in smoked meats or environmental pollutants. A free-radical is a highly reactive toxic-atom that can easily destroy body tissues.
Free radicals damage the delicate structure of the cells causing cellular aging. This type of cellular aging leads to other diseases including heart disease and cancer.
The good news is with a strong immune system and plenty of antioxidant-rich foods, free-radicals can be neutralized.
