Rectal Cancer: Symptoms, Causes, and Treatment

Rectal cancer is a type of cancer that starts in the rectum, the final part of the large intestine. It is significant because early detection and treatment are crucial for better outcomes. Rectal cancer is among the most common cancers worldwide, with a higher prevalence in older adults. Understanding the signs and symptoms, such as changes in bowel habits or blood in the stool, is vital for prompt medical attention. Regular screenings can help in early diagnosis and effective management of rectal cancer.

Causes of Rectal Cancer

Rectal cancer can develop due to various factors. These can include:

• Genetic mutations
• Family history of colorectal cancer
• Poor diet high in red or processed meats
• Smoking and alcohol consumption
• Inflammatory bowel diseases like Crohn's or ulcerative colitis

Symptoms of Rectal Cancer

Recognizing the symptoms of Rectal Cancer is crucial as early detection significantly improves outcomes. Being aware of the signs can lead to timely diagnosis and treatment. Symptoms of Rectal Cancer may include:

• Blood in the stool
• Changes in bowel habits (diarrhea, constipation, or narrowing of stools)
• Feeling like the bowel does not empty completely
• Abdominal discomfort (bloating, cramps, or pain)
• Unexplained weight loss
• Fatigue or weakness
• Anemia

Diagnosis of Rectal Cancer

Diagnosing Rectal Cancer accurately is crucial for timely treatment and better outcomes. Several diagnostic methods help determine the presence and extent of the disease:

• Digital rectal exam (DRE) to feel for lumps or abnormalities
• Colonoscopy for direct visualization of the rectum and biopsy
• Imaging tests like CT scans, MRI, and PET scans to assess tumor size and spread
• Endorectal ultrasound to evaluate tumor depth and lymph node involvement
• Blood tests to check for tumor markers like CEA

Treatment Options for Rectal Cancer

When it comes to treating Rectal Cancer, personalized care plays a pivotal role in achieving the best outcomes. Tailoring treatments to each individual's specific needs and circumstances is crucial. Here are the main approaches to treating Rectal Cancer:

Surgery

• Surgery involves removing the tumor and nearby healthy tissue.
• It is the primary treatment for early-stage rectal cancer.
• The main objective is to completely remove the cancerous tissue.
• The steps may include local excision, low anterior resection, or abdominoperineal resection.

Chemotherapy

• Chemotherapy uses drugs to kill cancer cells or stop their growth.
• It can be used before or after surgery to shrink tumors or eliminate remaining cancer cells.
• The primary goal is to destroy cancer cells throughout the body.
• Chemotherapy may involve several cycles of treatment over a specified period.

Radiation Therapy

• Radiation therapy uses high-energy rays to kill cancer cells.
• It is often used before surgery to shrink the tumor or after surgery to destroy remaining cancer cells.
• The main objective is to target and eradicate cancer cells in the rectal area.
• It typically involves daily treatments for several weeks.

Prevention and Management of Rectal Cancer

When it comes to preventing or managing Rectal Cancer, lifestyle changes and proactive measures play a crucial role in improving outcomes. Here's how you can take charge of your health:

Lifestyle Modifications:

• Eat a balanced diet rich in fruits, vegetables, and whole grains.
• Maintain a healthy weight through regular exercise and physical activity.
