What are the growth patterns of adenomas?

Healthcare providers categorize adenomas based on how they grow. They can be:

• Tubular: Grows in a round or oval shape and is most common in small (less than ½ inch) adenomas.
• Villous: Grows in a shaggy, cauliflower-like pattern and is most common in larger adenomas.
• Tubulovillous: A mixture of the two growth patterns.

Tubular adenomas are more common than villous adenomas. They are less likely to turn into cancer than villous adenomas.
