COLORECTAL CANCER: SYMPTOMS YOU SHOULDN'T IGNORE AND TREATMENT OPTIONS

Colorectal cancer, affecting the colon or rectum, is one of the most common cancers in India, with incidence rates rising steadily over the past two decades. The good news is that colorectal cancer is highly treatable when detected early, with survival rates exceeding 90 percent for early-stage disease. Understanding the symptoms, risk factors, and treatment options is essential for early detection and successful treatment.







Understanding Colorectal Cancer

Colorectal cancer begins when cells in the colon or rectum grow abnormally and form tumors. The colon and rectum are parts of the large intestine, responsible for processing waste and absorbing water and nutrients. Most colorectal cancers develop slowly over many years, typically starting as polyps, which are small growths on the inner lining of the colon or rectum. While not all polyps become cancerous, certain types, particularly adenomatous polyps, have the potential to transform into cancer over time.

Several factors increase the risk of developing colorectal cancer. Age plays a significant role, with most cases occurring in people over 50, though younger adults are increasingly being diagnosed. Family history matters, as individuals with close relatives who had colorectal cancer face higher risk. Personal medical history including inflammatory bowel diseases like ulcerative colitis or Crohn's disease, or previous colorectal polyps or cancer increases risk. Lifestyle factors such as diet high in red and processed meats, low in fiber, lack of physical activity, obesity, smoking, and heavy alcohol consumption all contribute to increased risk.

In India, changing dietary patterns, sedentary lifestyles, and increased life expectancy contribute to rising colorectal cancer rates, particularly in urban areas like Ahmedabad.

Warning Signs You Should Never Ignore

Early colorectal cancer often causes no symptoms, which is why screening is so important. However, as the disease progresses, various symptoms may appear. Persistent changes in bowel habits are often the first noticeable sign. This includes diarrhea, constipation, or changes in stool consistency lasting more than a few days, feeling that the bowel doesn't empty completely, or narrowing of stool (pencil-thin stools).

Blood in the stool is a serious warning sign, whether bright red or very dark. Abdominal discomfort including persistent cramps, gas, pain, or bloating should not be ignored. Unexplained weight loss without trying to lose weight warrants medical attention. Constant weakness or fatigue that doesn't improve with rest, and feeling that you need to have a bowel movement when there's no need to are also important symptoms to watch for.

Many people dismiss these symptoms, attributing them to hemorrhoids, diet changes, or stress. While these conditions can cause similar symptoms, it's crucial to consult a doctor for proper evaluation. In Indian culture, discussing bowel habits is often considered taboo, leading to delayed diagnosis. Overcoming this hesitation could save your life. Cancer hospitals in Ahmedabad like Zanish Cancer Hospital provide confidential, compassionate evaluation for digestive symptoms.

The Importance of Screening

Screening can detect colorectal cancer before symptoms appear and identify precancerous polyps that can be removed before they become cancerous. Current screening recommendations suggest that adults at average risk should begin screening at age 45, while those with risk factors may need to start earlier.

Several effective screening methods are available. Colonoscopy is considered the gold standard, allowing doctors to view the entire colon and rectum, remove polyps during the procedure, and is recommended every 10 years if results are normal. Flexible sigmoidoscopy examines the lower part of the colon and is performed every five years. Stool-based tests like fecal occult blood test (FOBT) or fecal immunochemical test (FIT) detect hidden blood in stool and should be done annually. CT colonography, or virtual colonoscopy, uses CT scanning to create images of the colon and is done every five years.

In India, colonoscopy facilities are available in most major cities and many district hospitals. At Zanish Cancer Hospital in Ahmedabad, state-of-the-art colonoscopy equipment and experienced gastroenterologists ensure comfortable, accurate screening. While some people fear the procedure, modern colonoscopy is performed under sedation and is generally painless. The temporary discomfort is minor compared to the life-saving benefits of early detection.

Diagnosis Process

When symptoms or screening tests suggest colorectal cancer, doctors follow a systematic diagnostic approach. Physical examination includes a digital rectal exam where the doctor manually checks the rectum for abnormalities. Blood tests check for anemia or tumor markers, though these alone cannot diagnose cancer. Colonoscopy with biopsy allows the doctor to examine the entire colon and rectum, take tissue samples from suspicious areas, and remove polyps for examination. Imaging studies such as CT scans, MRI, or PET scans help determine if cancer has spread to other organs.

If cancer is confirmed, staging determines how far it has spread. Stages range from Stage 0 (very early, confined to inner lining) through Stage IV (spread to distant organs like liver or lungs). Staging is crucial for treatment planning and prognosis estimation. Advanced diagnostic capabilities at specialized cancer hospitals in Ahmedabad ensure accurate staging and personalized treatment planning.

Comprehensive Treatment Options

Colorectal cancer treatment depends on the cancer stage, location, and the patient's overall health. Most treatment plans involve multiple approaches. Surgery is the primary treatment for most colorectal cancers and comes in various forms depending on cancer stage and location.

For early-stage cancers, polypectomy removes polyps during colonoscopy, while local excision removes small cancers from the rectum without major surgery. For more advanced cancers, colectomy involves removing part of the colon along with nearby lymph nodes. The remaining healthy portions of the colon are reconnected. In some cases, a temporary or permanent colostomy may be necessary, where a portion of the colon is brought through the abdominal wall to allow waste elimination into a bag.

Rectal cancer surgery is often more complex due to the rectum's location in the pelvis. Low anterior resection removes the tumor while preserving the anus, abdominoperineal resection removes the rectum and anus, requiring permanent colostomy, and transanal excision removes small, early-stage rectal tumors through the anus.

Minimally invasive surgical techniques, including laparoscopic and robotic surgery, offer several advantages. Smaller incisions result in less pain and scarring, shorter hospital stays, faster recovery times, and similar cancer outcomes compared to open surgery. Zanish Cancer Hospital, a leading cancer hospital in Ahmedabad, specializes in minimally invasive colorectal cancer surgery, offering patients advanced treatment with optimal outcomes.

Chemotherapy uses powerful drugs to kill cancer cells throughout the body. It may be administered before surgery to shrink tumors (neoadjuvant chemotherapy), after surgery to eliminate remaining cancer cells and reduce recurrence risk (adjuvant chemotherapy), or for advanced cancer to control disease and relieve symptoms.

Radiation therapy uses high-energy beams to destroy cancer cells and is often used for rectal cancer before surgery to shrink tumors, after surgery to eliminate remaining cancer cells, or for advanced cancer to relieve symptoms like pain or bleeding.

Targeted therapy and immunotherapy represent newer treatment approaches. Targeted therapy drugs attack specific abnormalities in cancer cells, including medications targeting EGFR (epidermal growth factor receptor) or VEGF (vascular endothelial growth factor). Immunotherapy helps the immune system recognize and attack cancer cells, particularly effective for tumors with specific genetic markers like microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR).

The Role of Surgical Oncology in Colorectal Cancer

Surgical oncology expertise is critical for optimal colorectal cancer outcomes. Specialized surgical oncologists bring several advantages. They have extensive experience performing complex colorectal cancer surgeries, can handle complicated cases including recurrent cancers or tumors involving adjacent organs, are skilled in minimally invasive techniques, and understand the nuances of lymph node removal and ensuring clear surgical margins.

The surgeon's experience significantly impacts outcomes. Studies show that patients treated by high-volume surgeons at specialized centers experience lower complication rates, better functional outcomes, reduced need for permanent colostomy, and improved long-term survival rates.

At Zanish Cancer Hospital in Ahmedabad, the surgical oncology team focuses not just on cancer removal but also on preserving quality of life. Sphincter-preserving surgery maintains bowel control when possible, nerve-sparing techniques preserve sexual and urinary function, and enhanced recovery protocols minimize hospital stays and speed recovery. This comprehensive approach makes Zanish Cancer Hospital one of the preferred cancer hospitals in Ahmedabad for colorectal cancer treatment.

Multidisciplinary Cancer Care

Effective colorectal cancer treatment requires coordination among multiple specialists. A comprehensive team typically includes surgical oncologists performing cancer removal, medical oncologists managing chemotherapy and targeted therapies, radiation oncologists providing radiation treatment, gastroenterologists performing diagnostic procedures and managing digestive issues, pathologists analyzing tissue samples and identifying genetic markers, radiologists interpreting imaging studies, nutritionists addressing dietary needs and managing side effects, stoma nurses helping patients adjust to colostomies if needed, and psychologists and counselors providing emotional support.

Regular multidisciplinary team meetings ensure that treatment plans are optimized for each patient's unique situation. This collaborative approach at Zanish Cancer Hospital leads to better outcomes and improved quality of life for colorectal cancer patients throughout Gujarat.

Living with and After Colorectal Cancer

Treatment completion marks the beginning of a new phase focused on recovery and monitoring. Follow-up care is essential and includes regular physical examinations every three to six months initially, then annually. Blood tests check for tumor markers like CEA (carcinoembryonic antigen), colonoscopy monitors for new polyps or cancer recurrence, and imaging studies like CT scans check for cancer spread.

Many patients experience side effects from treatment, including fatigue, changes in bowel habits, dietary restrictions or sensitivities, and sexual or urinary dysfunction following pelvic surgery. Working with your healthcare team helps manage these issues effectively.

Dietary and lifestyle adjustments can improve recovery and reduce recurrence risk. Eating a high-fiber diet with plenty of fruits, vegetables, and whole grains, limiting red and processed meat consumption, maintaining a healthy weight through balanced diet and regular exercise, engaging in physical activity for at least 150 minutes weekly, avoiding tobacco and limiting alcohol consumption, and managing stress through meditation, yoga, or counseling are all beneficial practices.

For patients with colostomies, adjustment takes time but most people adapt well and return to normal activities. Specialized nurses at cancer hospitals in Ahmedabad like Zanish Cancer Hospital provide training on stoma care, and support groups connect patients with others who have similar experiences.

Prevention Strategies

While not all colorectal cancer can be prevented, risk can be significantly reduced through several measures. Regular screening starting at age 45 is the most effective prevention strategy, detecting and removing precancerous polyps before they become cancer. Dietary modifications including eating plenty of fruits, vegetables, and whole grains, limiting red meat to a few times per week, avoiding processed meats like sausages and bacon, and choosing healthier cooking methods like grilling, baking, or steaming instead of frying all help reduce risk.

Maintaining physical activity through at least 30 minutes of moderate exercise most days helps maintain healthy body weight and reduces colorectal cancer risk. Weight management is crucial, as obesity significantly increases colorectal cancer risk. Limiting alcohol to no more than one drink per day for women and two for men, and avoiding tobacco in all forms are important preventive measures.

For individuals with family history or genetic conditions like Lynch syndrome or familial adenomatous polyposis (FAP), genetic counseling and testing may be recommended, along with earlier and more frequent screening starting in the 20s or 30s for some high-risk individuals, and in some cases, preventive medications or surgery.

Addressing Common Concerns

Many patients have concerns about colorectal cancer treatment. Regarding colostomies, while some patients require permanent colostomies, many are temporary, and modern stoma care products are discreet and effective, allowing most people to maintain active lifestyles. Surgical recovery varies, but minimally invasive approaches typically allow return to normal activities within four to six weeks. Most patients maintain good quality of life after treatment.

Treatment costs can be significant, but many government hospitals offer subsidized or free cancer treatment, private health insurance often covers cancer treatment, and NGOs and charitable organizations provide financial assistance for cancer patients. Don't delay treatment due to cost concerns; explore available support options with the financial counselors at Zanish Cancer Hospital or other cancer hospitals in Ahmedabad.

When to Consult a Specialist

You should seek consultation with a colorectal cancer specialist or surgical oncologist if you experience persistent bowel habit changes lasting more than two weeks, notice blood in your stool, experience unexplained weight loss or persistent abdominal pain, have a family history of colorectal cancer, are due for screening based on your age or risk factors, or have been diagnosed with colorectal cancer and need treatment planning.

Early consultation ensures access to comprehensive diagnostic evaluation, expert surgical care, coordinated multidisciplinary treatment, and the latest treatment options including clinical trials.
