What is prevention?
Cancerprevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer.
To prevent new cancers from starting, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor; anything that decreases your chance of developing cancer is called a cancer protective factor.
At the time of diagnosis, 58% to 64% of patients with carcinoids of the small intestine have metastatic disease in the regional lymph nodes or the liver.[1] Early surgical treatment should include removal of the mesentery by wedge resection and resection of lymph node metastases surrounding the mesenteric artery and vein to preserve intestinal vascular supply and to limit the intestinal resection.[2] With grossly radical tumor resections, patients may remain symptom free for extended periods of...

Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer.
Different ways to prevent cancer are being studied, including:
- Changing lifestyle or eating habits.
- Avoiding things known to cause cancer.
- Taking medicines to treat a precancerouscondition or to keep cancer from starting.
