In the United States, more than 30% of people over the age of 50 will develop diverticulosis, a condition marked by small pouches in the colon wall. While the disorder can lead to undesirable side effects, like inflammation, bleeding and constipation, diverticulosis does not appear to cause colon cancer.
How often does diverticulitis turn into cancer?
A minor risk factor for colorectal cancer is diverticulitis. Colorectal cancer has a 1.9% one-year incidence rate in patients with diverticulitis.
How do I know if I have diverticulitis or colon cancer?
Conclusion: When there are no pericolonic lymph nodes adjacent to a segment of colonic wall thickening, with pericolonic inflammatory changes, the most likely diagnosis is diverticulitis. When pericolonic lymph nodes are present, with or without pericolonic edema, the most likely diagnosis is colon cancer.
Will diverticulitis turn into cancer?
The risk of having colorectal cancer after an episode of acute diverticulitis is 44-fold higher than that of an age- and gender-adjusted reference population.
Can colon cancer be mistaken for diverticulitis?

After diverticulitis with abscess formation or free perforation (Hinchey I–IV), it was was 91 % (CI 75 to 100) after 5 years, 85 % (CI 62 to 103) after 10 years, and 69 % (CI 40 to 95) after 15 years. Figure 2 shows the estimated relative long-term survival in all patients in relation to ASA score at admission.
What are the symptoms of stage 1 colon cancer?
Early symptoms of colon cancer might include blood in the stool; persistent problems in defecating (long-lasting diarrhea or constipation); feelings of cramping, distension or pain in the area of the bowel; or a persistent decrease in the size of the stool.

What is considered severe diverticulitis?
The most common symptoms of simple diverticulitis are abdominal or pelvic pain, abdominal tenderness, and fevers. Complicated diverticulitis occurs when secondary complications results after an attack of diverticulitis, and these complications include abscess formation and perforation of the colon with peritonitis.
Is diverticulitis a serious condition?
Most people with diverticulitis recover completely. But, at its most severe, a pouch can burst open, spilling fecal matter directly into a person’s bloodstream. This results in an immediate risk of developing a blood infection called sepsis, which can be life-threatening.
What are the stages of diverticulitis?
