Colorectal Cancer

Colorectal cancer, which includes cancers of the colon and rectum, is the third most common type of cancer worldwide. Understanding the risks associated with this disease and the available treatment options can significantly improve outcomes and survival rates. This blog post aims to delve into these topics and shed light on colorectal cancer.

Understanding Colorectal Cancer

Colorectal cancer usually starts as benign growths, known as polyps, on the inner lining of the colon or rectum. Over time, these polyps can become cancerous. Symptoms of colorectal cancer include changes in bowel habits, abdominal discomfort, unexplained weight loss, and fatigue.

Risk Factors for Colorectal Cancer

Several risk factors increase the likelihood of developing colorectal cancer:

1. Age

While colorectal cancer can affect people of all ages, the risk significantly increases after the age of 50.

2. Family History

Having a close relative with colorectal cancer can increase your risk, especially if the relative was diagnosed at a young age.

3. Diet

A diet high in red or processed meats and low in fruits, vegetables, and whole grains can increase the risk of colorectal cancer.

4. Lifestyle Factors

Physical inactivity, obesity, smoking, and heavy alcohol consumption can all contribute to an increased risk of colorectal cancer.

5. Certain Medical Conditions

Individuals with a history of inflammatory bowel disease (Crohn’s disease or ulcerative colitis) are at a higher risk.

Treatment Options for Colorectal Cancer

There are several treatment options for colorectal cancer, and the choice often depends on the stage of the cancer and the patient’s overall health.

1. Surgery

Surgery is often the primary treatment for early-stage colorectal cancer. Polyps may be removed during a colonoscopy, or a segment of the colon or rectum may be removed (colectomy or rectal resection).

2. Chemotherapy

Chemotherapy, which uses drugs to destroy cancer cells, is typically used after surgery if the cancer has spread to lymph nodes.

3. Radiation Therapy

Radiation therapy uses high-energy rays to kill cancer cells and is often used in conjunction with chemotherapy for rectal cancer.

4. Targeted Therapies

These treatments target specific elements of cancer cells to stop their growth and spread.

5. Immunotherapy

This relatively new type of treatment boosts the body’s natural defences to fight cancer.


The risk of colorectal cancer can be significantly reduced by maintaining a healthy lifestyle, regular screening, and prompt attention to symptoms. While being diagnosed with colorectal cancer can be daunting, understanding the treatment options available can provide hope and lead to better outcomes. It’s essential to have open conversations with healthcare providers to make informed decisions about your health.
