Are small sessile colon polyps usually cancerous?

No ... ... On the contrary. The smaller the polyp, the less likely it is to be "cancerous". Sessile just means flat (harder to find) versus pedunculated (mushroom-shaped). The precancerous type of polyps are adenomatous and serrated polyps (documented on pathology). Hyperplastic polyps in general are almost always benign and never turn into cancer.

Are large, flat colon polyps cancerous more often that other polyps?

Yes. Truly either pedunculated ( i.E with stalk) or sessile (flat) can harbor a malignant or pre-malignant lesion. The flat ones are a little more worrisome, and size of lesion also plays a role. Biopsy is the key to diagnosis - if the lesion is large and flat, there is always the possibility that malignancy may exist elsewhere within the lesion and surgery or close follow up may be needed.
