Rectal cancer is a significant health concern that affects thousands of individuals each year. Understanding the complexities of this disease and the available treatment options is crucial for patients and their families. A Los Angeles colorectal surgeon offers invaluable insights and expertise in diagnosing, treating, and managing rectal cancer. This article explores the various aspects of rectal cancer, including risk factors, symptoms, diagnostic procedures, treatment options, and the importance of multidisciplinary care.
Understanding Rectal Cancer
Rectal cancer occurs when malignant cells form in the tissues of the rectum, the last part of the large intestine. Often developing from polyps, rectal cancer can go unnoticed in its early stages, which is why awareness and regular screenings are essential.
Risk Factors
Several factors can increase the risk of developing rectal cancer:
- Age: Individuals over 50 are at a higher risk.
- Family History: A family history of colorectal cancer or polyps can increase risk.
- Genetic Syndromes: Conditions such as Lynch syndrome and familial adenomatous polyposis significantly raise the likelihood of developing rectal cancer.
- Lifestyle Factors: Poor diet, physical inactivity, obesity, smoking, and heavy alcohol consumption can also contribute to an increased risk.
Understanding these risk factors is vital for individuals and their healthcare providers in developing preventive strategies.
Symptoms of Rectal Cancer
Rectal cancer may present with various symptoms, including:
- Changes in bowel habits (diarrhea or constipation)
- Blood in the stool
- Unexplained weight loss
- Abdominal discomfort or pain
- A feeling of fullness or the need to have a bowel movement despite an empty rectum
Recognizing these symptoms early can lead to prompt medical consultation and potentially lifesaving interventions.
The Role of a Los Angeles Colorectal Surgeon
A Los Angeles colorectal surgeon specializes in diagnosing and treating diseases of the colon, rectum, and anus. The expertise of such a surgeon is essential in managing rectal cancer effectively.
1. Diagnosis
The diagnosis of rectal cancer typically involves several steps:
- Medical History and Physical Exam: The surgeon will review the patient’s medical history and conduct a physical examination.
- Digital Rectal Exam (DRE): This procedure allows the surgeon to feel for any abnormalities in the rectum.
- Imaging Tests: CT scans or MRIs may be ordered to determine the extent of cancer spread.
- Colonoscopy: This vital procedure allows direct visualization of the rectum and colon, enabling the surgeon to take biopsies of any suspicious areas.
Accurate diagnosis is the cornerstone of effective treatment planning.
2. Treatment Options
Once diagnosed, treatment options for rectal cancer depend on the stage of the disease and the overall health of the patient. Common treatment modalities include:
a. Surgery
Surgery is often the primary treatment for rectal cancer. A Los Angeles colorectal surgeon may perform:
- Polypectomy: Removal of polyps during a colonoscopy.
- Local Excision: Removal of a small section of the rectum containing cancer.
- Rectal Resection: In more advanced cases, a more extensive section of the rectum may be removed, and the remaining parts may be reconnected.
b. Radiation Therapy
Radiation therapy uses high-energy rays to target cancer cells. It may be used before surgery (neoadjuvant therapy) to shrink tumors or after surgery (adjuvant therapy) to eliminate any remaining cancer cells.
c. Chemotherapy
Chemotherapy involves the use of drugs to kill cancer cells. It may be used in combination with other treatments, especially in more advanced stages of rectal cancer.
d. Targeted Therapy
Targeted therapies are newer treatments that target specific pathways involved in cancer growth. These may be an option for patients with specific genetic markers.
3. Multidisciplinary Care
Managing rectal cancer requires a collaborative approach. A Los Angeles colorectal surgeon works alongside oncologists, radiologists, nutritionists, and other healthcare professionals to provide comprehensive care. This multidisciplinary team approach ensures that all aspects of a patient’s health are considered and that treatment plans are tailored to individual needs.
Importance of Early Detection
Early detection of rectal cancer significantly improves treatment outcomes. Regular screenings, especially for individuals over 50 or those with risk factors, can lead to the identification of cancer at a more manageable stage. The five-year survival rate for rectal cancer is significantly higher when detected early, emphasizing the importance of preventive care.
Screening Guidelines
The American Cancer Society recommends that individuals begin regular screenings for colorectal cancer at age 45. Screening options include:
- Colonoscopy: Every ten years for average-risk individuals.
- Flexible Sigmoidoscopy: Every five years.
- CT Colonography: Every five years.
Following these guidelines can help in the early detection of rectal cancer, improving the chances of successful treatment.
Lifestyle Changes and Prevention
While not all cases of rectal cancer can be prevented, specific lifestyle changes can help reduce the risk. Recommendations include:
- Healthy Diet: A diet rich in fruits, vegetables, and whole grains can promote bowel health.
- Regular Exercise: Physical activity can help maintain a healthy weight and reduce cancer risk.
- Limiting Alcohol and Tobacco: Reducing alcohol consumption and avoiding tobacco can lower the risk of developing colorectal cancer.
Individuals can take proactive steps toward reducing their cancer risk by adopting a healthy lifestyle.

Conclusion
The expertise of a Los Angeles colorectal surgeon is vital in the battle against rectal cancer. Colorectal surgeons play an essential role in improving patient outcomes through early diagnosis, comprehensive treatment options, and a multidisciplinary approach. Regular screenings and awareness of symptoms are crucial for early detection, ultimately leading to better survival rates. For those facing the challenges of rectal cancer, consulting with a qualified colorectal surgeon, such as Dr. Armen Gregorian, MD, can provide the guidance and care needed to navigate this journey.
