Colorectal cancer is one of the most common cancers worldwide, ranking as the third most frequently diagnosed cancer and the second leading cause of cancer-related deaths. According to the World Health Organization, more than 1.9 million new cases of colorectal cancer were reported globally in 2020. These numbers highlight why it is critical to understand what is colorectal cancer, how it develops, its symptoms, and what treatment options exist. In Bangalore, patients benefit from the expertise of Dr. Mathangi J, Senior Consultant and In-charge of Radiation Oncology at Gleneagles Cancer Institute, who has treated over 12,000 cancer patients with advanced therapies.
When people ask about colorectal cancer meaning, they want a simple explanation of a complex disease. Colorectal cancer refers to cancers that begin in the colon or rectum, which are parts of the large intestine. These cancers usually start as small, benign growths called polyps, which may turn malignant over time. Understanding the meaning of colorectal cancer helps patients and families recognize that it is not just one disease, but a spectrum of conditions that can vary in aggressiveness and treatment requirements.
While many people use the term colon cancer interchangeably with colorectal cancer, there is a subtle distinction. Colon cancer specifically starts in the colon, while rectal cancer originates in the rectum. Together, they form colorectal cancer. Both share similar risk factors, such as poor diet, sedentary lifestyle, obesity, smoking, and genetic predisposition. Dr. Mathangi emphasizes that early detection of colon cancer greatly improves survival rates, and screening colonoscopies are a powerful tool to identify polyps before they become cancerous.
The colorectal cancer ICD 10 code is C18-C20, representing malignant neoplasms of the colon, rectosigmoid junction, and rectum. Accurate coding is important not only for insurance and hospital records but also for international cancer statistics and research. For patients, this classification means that healthcare professionals can track and compare treatment outcomes across the world, ensuring that therapies remain evidence-based and globally benchmarked.
Accurate colorectal cancer diagnosis is the cornerstone of successful treatment. Diagnosis typically involves a combination of:
At Gleneagles Cancer Institute, Dr. Mathangi leverages cutting-edge imaging and pathology support to ensure precision in diagnosis. This allows for a tailored treatment plan that maximizes effectiveness while minimizing side effects.
Recognizing symptoms of colorectal cancer is crucial for early detection. These include:
Unfortunately, many symptoms are vague and overlap with less serious conditions, which is why regular screening is essential, particularly for those above 45 years of age or with a family history of colorectal cancer.
Awareness campaigns often include content like colorectal cancer in Hindi to reach a wider audience in India. Communicating in regional languages ensures that vital health information is not lost due to language barriers. In states like Karnataka, Tamil Nadu, and across North India, delivering education about cancer symptoms and treatment in native languages empowers patients to seek timely care. Dr. Mathangi’s team contributes to awareness efforts that transcend linguistic boundaries, making life-saving knowledge accessible.
Colorectal cancer is highly treatable when detected early. Patients diagnosed at Stage I have survival rates exceeding 90%, while advanced Stage IV disease has significantly lower outcomes. This gap underscores why early screening and timely consultations with oncologists like Dr. Mathangi are critical. She stresses that prevention and detection should be community priorities, as delaying diagnosis leads to more aggressive treatment and reduced chances of survival.
As a Senior Radiation Oncologist with international training, Dr. Mathangi brings cutting-edge technologies into the treatment of colorectal cancer. She specializes in:
Her pioneering role in installing Asia Pacific’s first TrueBeam STx machine demonstrates her leadership in the field. These innovations not only improve survival outcomes but also enhance quality of life for patients.
According to Dr. Mathangi, cancers where radiation therapy is essential include:
Her department at Gleneagles Cancer Institute integrates these therapies into a patient-centered model that emphasizes holistic care, safety, and compassion.

Colorectal cancer meaning refers to cancers that arise in the large intestine’s last segments—the colon and the rectum. The disease spectrum ranges from early, polyp-derived tumors to locally advanced or metastatic disease. Understanding this meaning helps patients recognize why screening, accurate staging, and advanced radiotherapy planning with experts like Dr. Mathangi matter.
Colorectal cancer diagnosis is confirmed through colonoscopy and biopsy, then staged with imaging (CT/MRI/PET-CT) and blood markers (e.g., CEA). At Gleneagles Cancer Institute, Dr. Mathangi integrates imaging with precision radiotherapy planning to map the tumor, nodes, and organs at risk before recommending surgery, radiation, systemic therapy, or combined treatments.
The colorectal cancer icd 10 codes commonly span C18–C20 (malignant neoplasms of colon, rectosigmoid junction, and rectum). Accurate coding streamlines documentation, insurance, and registry reporting. For patients, it supports consistent care pathways and enables outcomes tracking that informs evidence-based decisions by specialists like Dr. Mathangi.
During your first visit, bring previous reports; her team will align your records with ICD-10 codes for seamless transition of care.
Symptoms of colorectal cancer may include persistent changes in bowel habits, rectal bleeding or blood in stool, abdominal cramps, unexplained weight loss, fatigue, and iron-deficiency anemia. These symptoms can overlap with benign conditions, so timely evaluation and screening with a specialist-led team are essential.
If you notice any of the above, contact Dr. Mathangi’s team for guidance.
Colon cancer starts in the colon, while rectal cancer starts in the rectum; together, they are termed colorectal cancer. Treatment depends on tumor location, stage, and biology. Under Dr. Mathangi’s care, patients receive individualized plans that may include surgery, systemic therapy, and advanced radiation (e.g., IGRT/RapidArc, SBRT, image-guided brachytherapy) to optimize control and preserve function.
For locally advanced rectal disease, short-course or long-course chemoradiation can shrink tumors pre-surgery and reduce recurrence risk.
