So, let us unravel the fascinating world of colorectal cancer markers and discover how they are revolutionizing the way we detect and manage this disease.

Understanding Colorectal Cancer

Before delving into colorectal cancer markers, it is crucial to understand the basics of this disease. Colorectal cancer is a type of cancer that originates in either the colon or the rectum. It is the third most common cancer in both men and women in the United States, with an estimated 149,500 new cases and 53,200 deaths expected in 2021 alone.

There are several risk factors associated with the development of colorectal cancer. These include age (the risk increases with age), a family history of the disease, a personal history of polyps or inflammatory bowel disease, a sedentary lifestyle, a diet high in red and processed meats, smoking, and excessive alcohol consumption.

The symptoms of colorectal cancer can vary, depending on the location and stage of the tumor. Some common symptoms include:

• Blood in the stool or rectal bleeding
• Changes in bowel movements, such as persistent diarrhea or constipation
• Abdominal pain or discomfort
• Unexplained weight loss
• Fatigue

Early detection of colorectal cancer is crucial for successful treatment and improved prognosis. This is why regular colorectal screening is highly recommended, especially for individuals over the age of 50 or those with a family history of the disease. Screening methods include:

1. Colonoscopy: This is the most effective screening tool for detecting colorectal cancer. It involves the examination of the entire colon and rectum using a flexible tube with a camera.
2. Fecal immunochemical test (FIT): This is a non-invasive test that detects hidden blood in the stool, which can be an early sign of colorectal cancer.
3. Flexible sigmoidoscopy: This procedure involves the examination of the lower third of the colon, using a flexible tube similar to a colonoscopy.

In addition to risk factors and screening methods, genetic mutations also play a significant role in the development of colorectal cancer. Certain inherited genetic mutations, such as those in the APC, MLH1, MSH2, and PMS2 genes, can increase the risk of developing this disease. Genetic testing may be recommended for individuals with a family history of colorectal cancer to identify these mutations and guide treatment decisions.

Risk Factors for Colorectal Cancer

Understanding the basics of colorectal cancer, including its risk factors, symptoms, and the importance of early detection through regular colorectal screening, is crucial for effective prevention and treatment.
