    some can not
   Many of these diseases have no cure but can be
        Causes of noninfectious diseases
   Genetics:
     Can inherit the gene that causes the disease
     Can be born with it
     Can be a characteristic that is a risk factor for
      a particular disease (race, skin color, age,

    is      cancerous
        Malignant – cancerous tumor
        Benign – non cancerous tumor
        Metastasis – the spread of cancer from where it first
         develops to other parts of the body
 Surgery – can remove part or all of the
  malignant tumor
 Radiation – can kill cancer cells or slow
 Chemotherapy – chemicals that kills the
  cells in an effort to kill cancerous ones

        Protecting Your Skin
 Always wear sun block, at least 15 SPF
 Avoid peak sun hours
 Protect your eyes
 Be familiar with moles, freckles, and any
  other skin imperfection
 See a dermatologist yearly, especially if
  skin cancer runs in the family or you spend
  a lot of time in the sun
   SPF means skin protective factor meaning the degree of
    which sunscreen protects your skin from direct rays.
   An SPF 10 means it protects you from 90% of the direct
    rays and that if you apply a SPF 10 then theoretically
    you can lay stay in the sun for 10 hours and get the
    equivalent of one hour unprotected sun.
   An SPF of 15 gives you 93% protection from the sun,
    An SPF of 30 gives you 97% as well as SPF 40.
   Apply liberally (1 ounce should cover entire body) and
    reapply after swimming or excessive sweating.
        Sunscreen vs Sunblock
   There are 2 types of rays:
     UVA which causes premature aging
     UVB causes cancer

 Sunscreen only protects you from UVA
 Sun block protects from both types of rays
 To protect your skin from both types of
  rays, look for ingredients: zinc oxide,
  titanium dioxide, and octocrylene
