Introduction:
The incidence of colorectal cancer varies from country to country and even among cities in the country. Overall statistics may mask important trends based on sex and age, so the detailed statistics will be more useful. This study aimed to investigate the trend of colorectal cancer from 2007 to the last formal published data (2019) in Isfahan, Iran.
Method:
Colorectal cancer incidence and age-standardized rate were calculated using both data from the Isfahan Cancer Registration Center and Iran and World Standard Population. STATA software was used to calculate the frequency and incidence rates as well as ASR.
Results:
The total number of diagnosed CRC cases changed from 344 to 1093 between 2007 and 2019 in Isfahan Province. About 55% of all new cases were men, and they also were older on the average than women when diagnosed with cancer. Crude rate and ASR of CRC increased from 9.6 in 2007 to 27 and 22.6 in 2019 per 100,000.
Conclusions:
Although we have observed an increase in the trend of colorectal cancer (CRC) cases, this trend is heavily dependent on cancer registration policies. This should be taken into account by policymakers, as to make an accurate judgment of the trend, a comprehensive, unified, and high-quality registration policy must be considered.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
