How does pancreatic cancer start?
How does pancreatic cancer
start?
Cancer is a disease of cells—the building blocks that
form tissue in the body. Normal cells grow and then
divide to make new cells. New cells are made as the
body needs them. When normal cells grow old or get
damaged, they die. Cancer cells don’t do this. Cancer
cells make new cells that aren’t needed and don’t die
quickly when old or damaged.
See Figure 2.
Over
time, cancer cells grow and divide enough to form a
primary tumor. Primary tumors can grow large and
invade nearby tissues.
