Colorectal Cancer
Colorectal cancer is known to be a common and potentially cancer. This issue is known to affect the colon or rectum. With early detection and timely treatment, many cases of colorectal cancer can be effectively managed or even cured.
Understanding Colorectal Cancer:
Colorectal cancer, also known as colon cancer or rectal cancer, occurs when abnormal cells grow uncontrollably in the colon or rectum, forming tumors. Over time, these tumors can invade nearby tissues and spread to other parts of the body, a process known as metastasis. Colorectal cancer often develops from precancerous polyps or adenomas that grow on the inner lining of the colon or rectum.
Risk Factors:
Several factors may increase the risk of developing colorectal cancer, including:
- Age: The risk of colorectal cancer increases with age, with the majority of cases diagnosed in individuals over 50 years old.
- Family History: A family history of colorectal cancer or certain hereditary conditions, such as familial adenomatous polyposis (FAP) or Lynch syndrome, can increase the risk of developing the disease.
- Personal History: Individuals with a personal history of colorectal cancer or certain types of polyps are at higher risk of developing the disease.
- Lifestyle Factors: Lifestyle factors, including a diet high in red and processed meats, low in fiber, lack of physical activity, obesity, smoking, and excessive alcohol consumption, may increase the risk of colorectal cancer.
- Inflammatory Bowel Disease: Chronic inflammatory conditions of the colon or rectum, such as ulcerative colitis or Crohn’s disease, can increase the risk of colorectal cancer.
Symptoms:
Common symptoms of colorectal cancer may include:
- Alterations in bowel habits, like constipation, diarrhea, or narrow stools
- Blood in the stool or rectal bleeding
- Abdominal discomfort, cramping, or pain
- Unexplained weight loss
- Fatigue or weakness
- Iron deficiency anemia
Screening and Early Detection:
Early detection through regular screening is crucial for improving colorectal cancer outcomes. Recommended screening tests may include:
- Colonoscopy: Colonoscopy is considered the gold standard for colorectal cancer screening and involves examining the entire colon and rectum with a flexible, lighted tube called a colonoscope.
- Fecal Occult Blood Test (FOBT): FOBT is a non-invasive test that checks for hidden blood in the stool, which may indicate the presence of colorectal cancer or precancerous polyps.
- Flexible Sigmoidoscopy: Flexible sigmoidoscopy is similar to colonoscopy but examines only the lower part of the colon and rectum.
- Stool DNA Test: Stool DNA testing detects specific genetic changes associated with colorectal cancer in stool samples and may be used as an alternative to other screening methods.
LifeCode’s Treatment Options:
LifeCode Healthcare offers a range of treatment options for colorectal cancer tailored to each individual’s unique needs and preferences. The multidisciplinary team of healthcare professionals collaborates to develop personalized treatment plans that may include:
-
Surgery:
- Colectomy: Surgical removal of the affected portion of the colon.
- Proctectomy: Surgical removal of the rectum.
- Polypectomy: Taking out of some small polyps while having a colonoscopy.
- Lymphadenectomy: Removal of nearby lymph nodes for staging purposes.
-
Chemotherapy:
- Adjuvant Chemotherapy: Chemotherapy may be recommended after surgery to reduce the risk of cancer recurrence.
- Neoadjuvant Chemotherapy: Chemotherapy may be given before surgery to shrink tumors and improve surgical outcomes.
- Palliative Chemotherapy: This is well used for overcoming symptoms and enhancing the quality of life for patients. This goes well with advanced-stage cancer.
-
Radiation Therapy:
- External Beam Radiation: High-energy beams are targeted at the tumor site to destroy cancer cells.
- Brachytherapy: Radioactive sources are placed directly inside the body near the tumor site to deliver targeted radiation.
- Adjuvant Radiation: Radiation therapy may be used after surgery to reduce the risk of cancer recurrence.
-
Targeted Therapy:
- Monoclonal Antibodies: Targeted therapy drugs, such as cetuximab and panitumumab, may be used to block specific proteins that promote cancer growth.
- Anti-Angiogenesis Drugs: Targeted therapy drugs, such as bevacizumab, may be used to inhibit the formation of new blood vessels that feed tumors.
-
Immunotherapy:
- Immune Checkpoint Inhibitors: Immunotherapy drugs, such as pembrolizumab and nivolumab, help the immune system recognize and attack cancer cells.
-
Clinical Trials:
- LifeCode Healthcare offers access to cutting-edge clinical trials investigating new treatments and therapies for colorectal cancer. It helps in providing eligible patients with opportunities to participate in innovative research and receive potentially life-saving interventions.
Preventive Measures:
While it may not be possible to prevent colorectal cancer entirely, certain lifestyle alterations and risk-reduction strategies might all help in lowering the risk:
- Maintain a Healthy Lifestyle: Eat a balanced diet rich in fruits, vegetables, and whole grains, limit red and processed meats, maintain a healthy weight, exercise regularly, avoid smoking, and limit alcohol consumption.
- Get Screened Regularly: Follow recommended screening guidelines based on age, family history, and other risk factors. Screening can help detect colorectal cancer early when it is most treatable.
- Know Your Family History: Be aware of your family’s history of colorectal cancer and discuss any concerns with your healthcare provider.
- Consider Genetic Counseling: If you have a family history of colorectal cancer or certain genetic conditions, consider genetic counseling and testing to assess your risk and explore preventive options.

Who should consider undergoing a colorectal cancer genetic test?
Individuals with a personal or family history of colorectal cancer, particularly those with multiple affected relatives or early-onset cases, may benefit from a colorectal cancer genetic test to assess their risk and guide medical management.
What specific genes does a colorectal cancer genetic test analyze, and how do they contribute to cancer development?
Colorectal cancer genetic tests analyze genes such as APC, MLH1, MSH2, MSH6, PMS2, and others associated with hereditary colorectal cancer syndromes, including familial adenomatous polyposis (FAP), Lynch syndrome (hereditary nonpolyposis colorectal cancer), and other inherited forms of the disease.
Are there lifestyle factors that interact with genetic predispositions identified through a colorectal cancer genetic test?
Yes, lifestyle factors such as diet, exercise, smoking, alcohol consumption, obesity, and exposure to environmental carcinogens can interact with genetic predispositions to influence colorectal cancer risk and outcomes.
How does a colorectal cancer genetic test contribute to precision medicine and personalized treatment plans?
A colorectal cancer genetic test allows for the identification of individuals at increased risk, enabling personalized screening, prevention, and treatment strategies tailored to each patient’s genetic profile, ultimately improving outcomes and quality of care.
What research advancements are expected in colorectal cancer genetic testing?
Ongoing research aims to further refine colorectal cancer genetic testing by identifying additional genetic risk factors, improving testing accuracy, expanding the range of conditions covered, and integrating genomic data into clinical practice for more effective colorectal cancer prevention and treatment strategies.
