Colorectal cancer is a leading cause of cancer death globally. Early detection through colonoscopic surveillance and removal of precancerous lesions significantly improves treatment outcomes and prevents invasive carcinoma.
Area of Science:
- Oncology
- Gastroenterology
- Pathology
Background:
- Colorectal cancer is a significant global health burden, ranking as the third most diagnosed cancer in men and second in women in the USA.
- It is the second leading cause of cancer-related deaths worldwide, accounting for nearly 916,000 deaths annually.
- Despite its prevalence, colorectal cancer is highly treatable due to the colon's accessibility and the efficacy of colonoscopic surveillance.
Purpose of the Study:
- To discuss the clinical and pathological features of malignant tumors affecting the colon, rectum, appendix, and anus.
- To highlight the role of colonoscopic surveillance in diagnosing precancerous polyps and invasive carcinoma.
- To emphasize the preventive potential of removing precancerous lesions during colonoscopy.
Main Methods:
- Review of clinical and pathological data for various colorectal tumors.
- Analysis of the diagnostic capabilities of colonoscopy.
- Evaluation of the effectiveness of endoscopic polyp removal in cancer prevention.
Main Results:
- Colorectal cancer presents a spectrum of epithelial, hematolymphoid, and mesenchymal malignancies.
- Colonoscopic surveillance is crucial for early diagnosis and tissue acquisition.
- Endoscopic removal of precancerous lesions effectively prevents the development of invasive colorectal cancer.
Conclusions:
- Colorectal cancer is a major public health concern, but it is treatable and preventable.
- Colonoscopic surveillance is a vital tool for both diagnosis and prevention of colorectal cancer.
- Understanding the diverse pathological features of colorectal tumors is essential for effective management.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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...
