Colorectal Adenomas Containing Carcinoma

The incidence of cancer in an adenoma increases as the size of the adenoma increases.

Thirty percent (30%) of villous adenomas > 5 cm contain an invasive carcinoma.

However, even a 4-mm adenoma may contain an invasive cancer (208).

Conversely, large sessileadenomas measuring >20 cm in greatest diameter without malignant change can be observed.
