Colonic Polyps Benign Tumors
Some: There are different types of colon polyps. Some will not turn into cancer. But many (adenomatous polyps in particular) have a high likelihood of turning into cancer if not removed.

If you have a precancerous polyp, it can be removed before you get cancer. ...Read moreSee 2 more doctor answers
A tumor by any other name is a growth. It can be either benign or malignant, differentiated based upon the potential to spread (a malignant tumor is, by definition, a cancer). The best way to determine this is by a tissue biopsy, but we can make better predictions based on the organ of origin, physical ...Read more
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. ...Read more
Some: Most people with colon cancer do not have a strong family history, but some do. Anyone with a family history of colon cancer and/or colonic polyps should have a screening colonoscopy well before the age recommended for people with no family history (50). See your physician.

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. ...Read moreSee 1 more doctor answer
Depends: A thymoma is a malignant tumor of the thymus, and the seriousness depends on details in the pathology report. An ectopic thymus and a hamartoma are both benign, but if the report says "thymoma" then it is probably malignant although not necessarily very serious if completely removed.
