Early Warning Signs of Rectal Cancer Identified

Guide to Detection, Diagnosis, and Treatment
Rectal cancer is a prevalent yet often overlooked type of cancer that affects the last part of the colon, known as the rectum. Despite its prevalence, many people remain unaware of the signs and symptoms associated with this disease, leading to delayed diagnosis and treatment.

This article aims to provide an in-depth understanding of rectal cancer, including its symptoms, risk factors, diagnosis, and treatment options. By increasing awareness of rectal cancer and encouraging early detection, we hope to improve the prognosis and survival rates for those affected by this condition.

Let’s Start Straight Away.

Understanding Rectum Cancer

Rectal Cancer is a type of Cancer that Develops in the Rectum, which is the final section of the large intestine (colon) where stool is stored before being expelled from the body. It is a subtype of colorectal cancer, which includes cancers that occur in both the colon and rectum.

The incidence of rectal cancer in India varies across different regions; however, it is generally lower than in Western countries. According to the National Institute of Cancer Prevention and Research (NICPR), colorectal cancer ranks as the seventh most common cancer among men and the ninth most common cancer among women in India.

While specific statistics on Rectal Cancer alone are limited, its incidence is expected to rise due to changes in lifestyle and dietary habits.

• Age: Rectal cancer is more common in people aged 50 and older, although it can occur at any age.
• Family history: Having a close relative with colorectal cancer increases the risk of developing rectal cancer.
• Personal history of colorectal polyps or cancer: Individuals who have previously had colorectal polyps or cancer are at a higher risk of developing rectal cancer.
• Inflammatory bowel disease: People with inflammatory bowel diseases, such as Crohn’s disease or ulcerative colitis, have an increased risk of rectal cancer.

• Diet: A diet high in red and processed meats, low in fiber, fruits, and vegetables may increase the risk of rectal cancer.
• Lifestyle factors: Lack of physical activity, obesity, and smoking can also contribute to a higher risk of developing rectal cancer.
• Understanding these Risk factors and maintaining a healthy lifestyle can help reduce the Risk of Rectal Cancer.

What are the Symptoms of Rectal Cancer?

Symptoms of rectal cancer can vary among individuals, and some may not exhibit symptoms during the early stages. However, it is essential to be aware of the possible signs and consult a doctor if any persist or worsen.

• Common Symptoms of Rectal Cancer Include:

• Changes in bowel habits: This may include diarrhea, constipation, or alternating between the two, lasting for more than a few days.

• Rectal Bleeding: Bright red blood in the stool or on toilet paper after wiping can be a sign of rectal cancer.

• Blood in the stool: Dark, tarry stools or stools with blood mixed in may indicate rectal cancer.

• Abdominal pain or discomfort: Persistent abdominal pain, cramps, gas, or bloating could be associated with rectal cancer.

• Feeling of incomplete bowel movements: A constant urge to have a Bowel Movement or a sensation that the bowel does not empty completely can be a symptom of rectal cancer.
  
  

Understanding causes associated with colon cancer is crucial for early detection and treatment. Age, personal or family history of colon cancer or polyps, inflammatory bowel disease, and certain inherited syndromes are known to Heighten the Risk.

• Unexplained Weight Loss: Losing weight without any changes in diet or exercise habits may be a sign of rectal cancer.
• Fatigue or weakness: Rectal cancer can cause chronic fatigue or general weakness, often due to anemia from blood loss.
  
  Narrow Stools: Thinner-than-normal stools, sometimes described as “pencil-thin,” can be a symptom of rectal cancer.
  
  It is important to note that these symptoms can also result from non-cancerous conditions, such as hemorrhoids, Irritable bowel syndrome (IBS), or inflammatory bowel disease (IBD).

However, if you experience any of these symptoms consistently, it is crucial to Consult GI cancer specialist for a proper evaluation and Diagnosis.Early detection and treatment of rectal cancer can significantly improve the prognosis and Outcomes.

What are the Symptoms of Rectal Cancer?

Diagnosis of rectal cancer involves a combination of physical examinations, tests, and procedures to determine the presence and extent of cancer. These diagnostic methods may include:

• Physical exam: The doctor will begin with a thorough examination, which may involve a digital rectal exam (DRE). During a DRE, the doctor inserts a gloved, lubricated finger into the rectum to feel for any abnormalities or masses.
• Stool tests: Stool tests can help detect blood in the stool, which may be a sign of rectal cancer. The fecal occult blood test (FOBT) or fecal immunochemical test (FIT) are commonly used for this purpose.
• Imaging tests: Imaging tests help visualize the rectum and surrounding structures to identify tumors or abnormalities. Some common imaging tests for rectal cancer diagnosis include:

• Colonoscopy: A thin, flexible tube with a camera on the end (colonoscope) is inserted through the rectum, allowing the doctor to examine the entire colon and rectum.
• Biopsies: A biopsy involves removing a small sample of tissue from the suspicious area for examination under a microscope. During a colonoscopy or sigmoidoscopy, the doctor can take a biopsy using special tools passed through the scope.
  The pathologist then examines the sample to determine if cancer cells are present and, if so, the type and grade of cancer.
  

• Flexible sigmoidoscopy: Similar to a colonoscopy, but only examines the lower part of the colon, including the rectum.
• Endorectal Ultrasound: A probe is inserted into the rectum, using sound waves to create images of the rectum and nearby tissues. This helps determine the depth of tumor invasion and if lymph nodes are involved.
• Computed tomography (CT) Scan: A CT scan creates detailed cross-sectional images of the body, which can help identify tumors and assess their spread.
  Magnetic resonance imaging (MRI): An MRI uses powerful magnets and radio waves to generate detailed images of the rectum and surrounding tissues, which can help plan treatment strategies.

Treatment & Prognosis for Rectal Cancer

Treatment for rectal cancer depends on the stage of the cancer, the patient’s overall health, and personal preferences. Common treatment options include:

• Surgery: Surgery is often the primary treatment for rectal cancer, with the goal of removing the tumor and surrounding tissue. Surgical options include:
• Local Excision: For early-stage rectal cancer, a surgeon may remove the cancerous tissue and a small portion of the surrounding healthy tissue through the anus.
• Low anterior Resection (LAR): In this procedure, the surgeon removes the cancerous part of the rectum and nearby lymph nodes, reconnecting the healthy portions of the rectum and colon.
• Abdominoperineal resection (APR): This surgery involves removing the entire rectum, part of the colon, and the anal opening. A colostomy is created to allow waste to exit the body.

• Chemotherapy: Chemotherapy uses drugs to destroy cancer cells or prevent them from growing. It can be administered before surgery (neoadjuvant chemotherapy) to shrink the tumor or after surgery (adjuvant chemotherapy) to kill any remaining cancer cells.
• Radiation therapy: Radiation therapy uses high-energy rays to destroy cancer cells. Like chemotherapy, radiation therapy can be used before surgery to shrink the tumor or after surgery to kill any remaining cancer cells. It may also be used in combination with chemotherapy to enhance treatment effectiveness.
• Targeted therapy: Targeted therapies are drugs that specifically target the changes in cancer cells that help them grow and divide. These therapies may be used in combination with chemotherapy or other treatments for advanced rectal cancer.
• Immunotherapy: Immunotherapy helps boost the body’s immune system to recognize and attack cancer cells. It may be an option for patients with advanced rectal cancer that has not responded to other treatments.

Prognosis for Rectal Cancer

The prognosis for rectal cancer varies depending on the stage at diagnosis, the patient’s overall health, and the effectiveness of the treatment. Early detection and treatment are crucial for a better prognosis. The survival rate for rectal cancer is relatively high when detected early.

Several factors can affect the prognosis, including the stage of the cancer, the type and grade of cancer cells, the patient’s age and overall health, and the effectiveness of the treatment plan.
It is essential to maintain regular follow-ups with your doctor to monitor your progress and ensure the best possible outcome.
