Vegetables and fruits contain vitamins and antioxidants that prevent the growth of Cancer. This is similar to the defence against infections. The immune mechanism will destroy what it finds abnormal. They also contain fibre that helps to prevent Colon Cancer. A high fibre diet prevents Colon Cancers because it dilutes the Cancer-causing irritant and also makes the motion move faster.
Cancer is commonly a disease of old age.
It can affect the young. Especially those who carry defective genes. These genes in the presence of environmental factors cause Cancer. They grow very fast. But younger people withstand treatment better.
