Although cancer may originate in many regions of the body, many patients die from cancerous growth in the lungs, lymph glands, or liver. This is most readily explained as

A) spreading of cancer by angiogenesis.
B) metastasis occurring more commonly in organs that have a filter effect.
C) proteinase enzymes making cancer particularly damaging to these tissues.
D) growth anywhere but in these organs is called benign.
E) due to these organs simply being more susceptible to cancer.
