diagnosis is so very important in the discovery of cancer.
a small nodule (smaller than a pea) can often go un-detected
by self-examination. IF your life was saved by early discovery
of a malignant growth, the discomfort and aggravation would be
worth it. here are a couple of sites about the susan komen
foundation, was founded in 1982 by Nancy Brinker to honor of the
memory of her sister, Susan Komen, who died from breast cancer .

another test which proves successful in early detection of
cancer is the colonoscopy....in which the colon is viewed and
this can prevent serious illness and death by early diagnosis.
