What is Rectal Cancer?
Rectal cancer is a type of malignancy that develops in the cells of the rectum, which is the lower part of the large intestine located just above the anus. It is a subset of colorectal cancer, which also includes cancers originating in the colon.
Rectal cancer occurs when normal cells in the rectum undergo abnormal changes and grow uncontrollably, forming a tumor. If left untreated, the cancer cells can spread to nearby lymph nodes and other organs through the bloodstream, a process known as metastasis.

Understanding the Rectum and its Function
The rectum is the terminal part of the large intestine, approximately 12-15 cm long, located just before the anus. Its main function is to store feces until they are ready to be expelled from the body during bowel movements. The rectum’s muscular walls allow it to stretch and accommodate waste material, and its lining detects the presence of stool, signaling the urge for defecation.
. The coordinated contraction and relaxation of the rectal muscles enable the controlled release of feces through the anus. Maintaining the rectum’s health and proper functioning is crucial for normal bowel control and overall digestive health.
Rectal Cancer Statistics and Prevalence
Rectal cancer is a significant global health concern. As part of colorectal cancer, it ranks as the third most commonly diagnosed cancer in both men and women. The incidence of rectal cancer varies worldwide due to factors such as lifestyle, genetics, and access to healthcare. Dr. Mohit Agarwal is renowned for his expertise as one of the best doctors for rectal cancer in New Delhi.
His specialization in oncology, with a focus on colorectal cancer, makes him a preferred choice for patients seeking the best rectal cancer doctor in Delhi or nearby. Early detection, regular screenings, and prompt medical attention are essential for improving outcomes in rectal cancer cases.
Types and Stages of Rectal Cancer
Adenocarcinoma: The Most Common Type
Adenocarcinoma is the most prevalent type of rectal cancer, accounting for the majority of cases. It originates from the glandular cells that line the inner surface of the rectum. These cells undergo abnormal changes and start to grow uncontrollably, forming tumors. Adenocarcinoma can develop in various parts of the body, but in the context of rectal cancer, it specifically refers to tumors in the rectal region.
Early detection and appropriate treatment are essential for improving the prognosis of adenocarcinoma, making it vital to undergo regular screenings, especially for individuals with risk factors such as a family history of colorectal cancer.
Squamous Cell Carcinoma and Other Rare Types
While adenocarcinoma is the most common type of rectal cancer, squamous cell carcinoma and other rare types can also occur. Squamous cell carcinoma arises from the squamous cells that make up the surface lining of the rectum. Compared to adenocarcinoma, squamous cell carcinoma is less frequent and may present unique challenges in diagnosis and treatment. Other rare types of rectal cancer include neuroendocrine tumors, gastrointestinal stromal tumors (GISTs), and sarcomas.
Diagnosis and treatment of these rare types often require a multidisciplinary approach, involving specialists like Dr. Mohit Agarwal, a reputed doctor for rectal cancer in New Delhi, to provide optimal care.
Staging of Rectal Cancer: TNM Classification
Staging is a crucial aspect of diagnosing and managing rectal cancer. The TNM (Tumor, Node, Metastasis) classification system is commonly used to stage rectal cancer and other malignancies. “T” indicates the size and extent of the primary tumor, “N” indicates the involvement of nearby lymph nodes, and “M” indicates the presence or absence of distant metastases. The combination of these factors helps determine the stage of rectal cancer, which influences treatment decisions.
Early-stage cancers have a higher likelihood of successful treatment, whereas advanced-stage cancers may require more aggressive therapeutic approaches. Accurate staging, along with the expertise of a top rectal cancer doctor like Dr. Mohit Agarwal in Delhi, is vital for effective treatment planning.
Importance of Staging for Treatment Planning
Staging plays a critical role in planning the most appropriate treatment for rectal cancer patients. Based on the extent of the disease, treatment options may include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these modalities. Staging helps oncologists like Dr. Mohit Agarwal, renowned for his expertise as one of the best rectal cancer doctors in Delhi, tailor treatments to the individual’s specific needs.
Early-stage cancers may be eligible for curative-intent treatments, while advanced stages may focus on palliative care to alleviate symptoms and improve quality of life. Accurate staging ensures that patients receive the most effective and suitable treatment, leading to better outcomes and improved chances of recovery.
Symptoms and Early Detection
Common Symptoms of Rectal Cancer
Symptoms of rectal cancer may include changes in bowel habits such as persistent diarrhea or constipation, blood in the stool (either bright red or dark), abdominal discomfort or pain, a feeling of incomplete bowel movement, unintentional weight loss, weakness, and fatigue. However, it's important to note that these symptoms can also be caused by various other conditions. If any of these symptoms persist or worsen, it is essential to seek medical evaluation and screening for early detection and timely treatment.
Importance of Early Detection and Screening
Early detection of rectal cancer significantly improves treatment outcomes and survival rates. Regular screenings, such as colonoscopies and fecal occult blood tests, can identify precancerous polyps or early-stage cancer, allowing for prompt intervention. Early detection provides more treatment options, including curative surgery, and reduces the need for aggressive treatments required at advanced stages. Considering the risk factors and potential symptoms, individuals over the age of 50 or with a family history of colorectal cancer should prioritize regular screenings.
Diagnostic Tests: Digital Rectal Exam, Colonoscopy, Imaging
Various diagnostic tests aid in the detection and staging of rectal cancer. A digital rectal exam (DRE) involves the physical examination of the rectum by a healthcare professional to detect any abnormalities. Colonoscopy is a standard procedure to visualize the rectum and colon for polyps or tumors and can also be used for biopsy and polyp removal. Imaging techniques, such as CT scans, MRI, and PET scans, help determine the extent of cancer spread to nearby lymph nodes and other organs. These tests assist in accurate diagnosis and treatment planning under the care of experts like Dr. Mohit Agarwal, a highly-regarded rectal cancer doctor in Delhi.
Rectal Cancer Treatment Options
Surgery: Local Excision, Low Anterior Resection, Abdominoperineal Resection
Surgery is a common treatment for rectal cancer, with various techniques depending on the stage and location of the tumor. Local excision is used for early-stage, small tumors confined to the rectal lining. For more advanced cases, a low anterior resection removes the tumor while preserving most of the rectum and rejoining it to the colon.
In cases where sphincter preservation is not feasible, an abdominoperineal resection involves removing the rectum and anus, with the creation of a permanent colostomy. Surgical intervention is often combined with other treatments to improve outcomes.
Chemotherapy: Adjuvant and Neoadjuvant
Chemotherapy uses drugs to target and kill cancer cells. Adjuvant chemotherapy is administered after surgery to eliminate any remaining cancer cells and reduce the risk of recurrence. Neoadjuvant chemotherapy is given before surgery to shrink the tumor, making it more amenable to surgical removal. Both approaches aim to increase the chances of successful treatment and improve long-term outcomes for rectal cancer patients.
Radiation Therapy: External Beam and Brachytherapy
Radiation therapy uses high-energy rays to target and destroy cancer cells. External beam radiation delivers radiation from outside the body, precisely targeting the tumor. Brachytherapy involves placing a radioactive source inside or near the tumor. Radiation therapy is often used in combination with surgery or chemotherapy to treat rectal cancer, particularly for cases with locally advanced tumors or as part of a neoadjuvant approach to downsize the tumor before surgery.
Combined Modality Treatment for Advanced Stages
Advanced rectal cancer may require a combination of treatments, such as chemoradiation therapy before surgery, followed by additional chemotherapy after surgery to reduce the risk of recurrence. In some cases, targeted therapies may also be used in conjunction with standard treatments to target specific molecular abnormalities present in the cancer cells, leading to more effective and personalized treatment approaches.
Targeted Therapy and Immunotherapy in Rectal Cancer
Targeted therapy involves drugs that specifically target certain proteins or genes in cancer cells, blocking their growth or signaling pathways. Immunotherapy helps the body’s immune system recognize and attack cancer cells more effectively. While these treatments have shown promising results in other cancer types, their application in rectal cancer is still under investigation through clinical trials. Dr. Mohit Agarwal, a leading doctor for rectal cancer in New Delhi, can guide patients about the latest treatment options and their suitability for individual cases.
Colostomy and Stoma Care
Understanding Colostomy and Its Role
A colostomy is a surgical procedure that creates an opening (stoma) on the abdominal wall, allowing a portion of the colon to be brought to the surface. This helps divert feces from the rectum when normal bowel function is impaired due to rectal cancer or other conditions. The stoma allows waste to exit the body and is collected in a special bag attached to the abdomen. Understanding the role of colostomy is crucial for patients undergoing rectal cancer treatment, as it may significantly impact daily life and self-care routines. Seeking guidance from an experienced doctor for rectal cancer in New Delhi, like Dr. Mohit Agarwal, can help patients cope with the changes and manage stoma care effectively.
Coping with Colostomy and Stoma Care
Coping with colostomy and stoma care involves adapting to the physical and emotional adjustments after surgery. Patients need to learn how to empty and change the stoma bag, maintain proper hygiene, and handle potential issues like skin irritation. Stoma care products and support from stoma care nurses can be immensely helpful in this process. Dr. Mohit Agarwal, a top rectal cancer doctor in Delhi, can provide valuable guidance and resources for colostomy patients, ensuring they receive the best care and support to maintain their quality of life and overall well-being.
Emotional and Practical Support for Colostomy Patients
Colostomy patients may face emotional challenges in accepting the changes brought about by the procedure. Emotional support from family, friends, and mental health professionals is essential in helping patients cope with anxiety, depression, or body image concerns. Practical support in learning stoma care, dietary adjustments, and lifestyle modifications is equally crucial. Reputable doctors for rectal cancer in New Delhi, like Dr. Mohit Agarwal, offer comprehensive care, including emotional and practical support, to ensure patients receive the holistic care they need to navigate the challenges associated with colostomy and stoma care.
Managing Treatment Side Effects
Coping with Chemotherapy and Radiation Side Effects
Chemotherapy and radiation therapy are common treatments for rectal cancer, but they can bring about various side effects. Patients may experience fatigue, nausea, vomiting, hair loss, and changes in appetite. Coping with these side effects requires open communication with healthcare providers to manage symptoms effectively.
Proper hydration, a balanced diet, and sufficient rest are essential to help the body tolerate the treatments better. With expertise in rectal cancer treatment, Dr. Mohit Agarwal, a top doctor in Delhi, can guide patients through these side effects and offer support to enhance their treatment experience.
Nutritional Support during Treatment

Proper nutrition contributes to overall well-being, strengthens the immune system, and aids in recovery.
