DIET AND CANCER
Cancer is the second
leading cause of death in the United States. It is a disease characterized by
abnormal cell growth and can occur in any organ. In some way the genes lose
control of cell growth, and reproduction becomes unstruc-tured and excessive.
The developing mass caused by the abnormal growth is called a tumor, or neoplasm. Cancer is also called
neoplasia. Cancerous tumors are malignant, affecting the
structure and consequently the function of organs. When cancer cells break away
from their original site, move through the blood, and spread to a new site,
they are said to metastasize. The mortality rate
for cancer clients is high, but cancer does not always cause death. When it is
found early in its development, prompt treatment can eradicate it. Oncology is the study of cancer,
and a physician who specializes in cancer cases is called an oncologist.
