What is dysplasia in colon?
“Dysplasia” is a term that describes how much your polyp looks like cancer under the microscope. Polyps that are only mildly abnormal are said to have low-grade (mild or moderate) dysplasia, while polyps that are more abnormal and look more like cancer are said to have high-grade (severe) dysplasia.
How long does it take for low-grade colon dysplasia to turn into cancer?
The process is estimated to take 10 years — a period that leaves ample opportunity for early discovery and treatment. We’ll get to the detection part, but first, let’s explain what goes into a colon polyp forming and turning cancerous.
Does colon dysplasia always lead to cancer?
Dysplasia is another pre-cancerous condition. It means there’s an area in a polyp or in the lining of the colon or rectum where the cells look abnormal, but they haven’t become cancer.
What is cytologic dysplasia?
Cytological dysplasia is evident at low magnification and occupies the full thickness of the epithelium. The columnar dysplastic cells have basal hyperchromatic nuclei with pseudostratification, increased mitotic activity and loss of polarity and cytoplasm ranges from eosinophilic to amphophilic.
How is colon dysplasia treated?
If the lesion is flat with low-grade dysplasia, one can either suggest colectomy (especially if multifocal) or repeat the colonoscopy in three to six months to look for other evidence of dysplasia (which, if present, colectomy would be recommended).
How is colon dysplasia diagnosed?
Diagnosis of dysplasia Dysplasia-associated lesion or mass (DALM) detected by colonoscopy in long-standing ulcerative colitis an indication for colectomy.
How is dysplasia treated?
In most cases, mild dysplasia resolves on its own and doesn’t become cancerous. Your doctor may recommend follow-up in a year to check for additional changes. If you have severe dysplasia (CIN II or III), your doctor may recommend treatment, such as surgery or other procedures to remove the abnormal cells.
What is high grade dysplasia?
High grade dysplasia (HGD) refers to precancerous changes in the cells of the esophagus. Gastroesophageal reflux disease (GERD) can be complicated by Barrett’s esophagus (BE), a change in the normal esophageal cells to intestinal-like cells. BE cells can become abnormal or dysplastic.
Is high grade dysplasia in colon cancer?
Polyps that are only mildly abnormal are said to have low-grade (mild or moderate) dysplasia, while polyps that are more abnormal and look more like cancer are said to have high-grade (severe) dysplasia. As long as your polyp has been completely removed and does not show cancer, you do not need to worry about dysplasia in your polyp.

Are all colon polyps precancerous or worse?
These types of polyps are not cancer, but they are pre-cancerous (meaning that they can turn into cancers). Someone who has had one of these types of polyps has an increased risk of later developing cancer of the colon. Most patients with these polyps, however, never develop colon cancer.
