Intestinal Polyps Are Benign Neoplasms and the First Stage in Development

Intestinal polyps are benign neoplasms and the first stage in development of colon cancer.These findings support the notion that:

B) an accumulation of mutations in specific genes is required for the development of cancer.
C) tumor invasion and metastasis progress more slowly in the gastrointestinal tract.
D) apoptosis is triggered by diverse stimuli including excessive growth.
