About this trail:
cancer is essentially a disease of mitosis. cancer begins when a single cell transform, or converts from a normal call to a cancer cell. DNA mutation occurs in one genes control growth.

  • cancer cells can't die
  • normal cells divide about 50 times then die.
  • cancer cells have unusual numbers of chromosomes
mitosis and cancer are related because they are forms in with cells multiply and divide to produce new cells and  help the organism survive.

It is probably most sensible not to deliberately sun bathe at all. But if you are going to then
  • Cover up with a hat, long sleeved shirt and trousers if you are out in the sun when it is hottest        
  • Do not sit in the sun when it is hottest - during noon and 3pm         
  • Wear a sunscreen of at least protection factor 15 and reapply it regularly.  Generally, the higher the sun protection factor (SPF) the better, particularly for children.
  • stop smoking
  • try eating healthy, eat 5 portions of fruit and vegetables a day, eat plenty of fiber, cut down on fat, salt,and sugar.
  • keep your sun exposure low, particularly if you are fair skinned.
