The striking example in The Journal of the American Medical Association aims to prove ________.
A: the five years following surgery is dangerous in that there is much likelihood to have recurrence.
B: surgical removal is not reliable because it could not eliminate all cancer cells of colon cancer.
C: The Journal of the American Medical Association often reports the latest discovery in science.
D: Western diet, in some uncertain way, excites the growth of cancer cells after the surgery.

- Lung cancer is the No.1 cancer to kill American people. No cancer kills more American than lung cancer.
- EGCG can inhibit the growth of cancer cells or induce apoptosis of cancer cells through multiple pathways, among which the key mechanism is achieved mainly through ( ). A: anti-angiogenesis B: blocking the growth cycle of cancer cells C: inhibiting the expression of some transcription factors D: regulating cell-related signal transduction mechanism
- The American Medical Association was founded in 1847 they produced a work called the first edition of the American Medical Association Code of Medical Ethics.
- We evaluated the associations between serum omega-3 and omega-6 poly-unsaturated fatty acid levels and colon cancer risk in a study conducted between 1997 and 2002. We included 363 cases of colon cancer and 498 disease-free controls. Serum omega-3 poly-unsaturated fatty acid levels were inversely associated with colon cancer risk. Subjects in the upper 33% of serum omega-3 poly-unsaturated fatty acids had a 33% lower risk of colon cancer as compared with subjects in the lower 33% of serum omega-3 poly-unsaturated fatty acids. In contrast, the risk of colon cancer was increased by omega-6 poly-unsaturated fatty acids by 68%. This is the first study that simultaneously finds an inverse association of serum omega-3 poly-unsaturated fatty acids and a positive association of omega-6 poly-unsaturated fatty acids with colon cancer. The study design is a:
- The American Medical Association supports smoking and published research on the subject.
