Colorectal cancer ranks among the most common cancers and affects both men and women. Detecting cancer at an early stage improves treatment outcomes and survival rates. By understanding the disease, its symptoms, causes, and available treatments, individuals are more equipped to seek timely medical intervention and improve their prognosis.
What Is Colorectal Cancer?
Colorectal cancer begins in the colon or rectum, organs that make up the lower part of the digestive system. It typically starts as growths called polyps, which form on the inner lining of the colon or rectum. While most polyps are noncancerous, some can develop into cancer over time. Early-stage colorectal cancer is often confined to the colon or rectum, while advanced stages may spread to other parts of the body.
This type of cancer falls under the category of gastrointestinal cancers and is often classified based on its location. Colon cancer occurs in the colon, while rectal cancer develops in the rectum. Screening tests, such as colonoscopies, are used to detect polyps or cancer in its earliest stages.
What Are the Symptoms?
This cancer often doesn’t show symptoms in its early stages, making regular screenings valuable. When symptoms do appear, they can vary widely and should not be ignored.
- Changes in bowel habits
- Rectal bleeding or blood in the stool
- Darker-than-usual stools
- Unexplained weight loss
- Abdominal pain or discomfort
- Persistent fatigue
Early detection can make a significant difference in treating this cancer.
What Causes It?
Risk factors for this cancer include age (50 years or older), a family history of colorectal cancer, and genetic mutations, such as those associated with Lynch syndrome. Lifestyle factors also play a role. Diets high in red and processed meats, low physical activity, smoking, and excessive alcohol consumption are linked to an increased risk of this cancer.
Chronic conditions that affect the digestive system, such as inflammatory bowel disease, ulcerative colitis, or Crohn’s disease, may also contribute. Obesity and type 2 diabetes are associated with a higher risk. While some risk factors are unavoidable, lifestyle changes can mitigate others.
What Are the Benefits of Early Detection?
Detecting cancer early has an impact on treatment success and survival rates. When caught in its initial stages, colorectal cancer is usually localized and easier to treat effectively. Treatments are often less invasive at this stage, which reduces recovery time and improves quality of life.
Early detection may also prevent cancer entirely. Colonoscopies enable physicians to identify and remove polyps before they develop into cancer. This preventive aspect makes routine screening a key part of healthcare for individuals within higher-risk categories.
How Is Colorectal Cancer Treated?
Treatment varies depending on the stage and individual factors. Early-stage cancer is often managed through minimally invasive surgery, which involves removing cancerous polyps or small sections of the colon or rectum. This approach is typically sufficient when cancer is confined to the inner layers of these organs.
More advanced cases often require a combination of treatments. Surgery may involve partial or total removal of the colon or rectum. Chemotherapy targets cancer cells that may have spread beyond the original site and is used before or after surgery to reduce tumor size or eliminate lingering cancer cells. Radiotherapy may also be employed to destroy cancer cells.
