Colon vs rectal
Colon cancer is treated primarily with surgery and chemotherapy. Rectal cancer often requires combined chemoradiation before surgery for the best outcome.
Colorectal Cancer Treatment in Hyderabad
Colorectal cancer is the fastest-growing cancer in young adults in Indian metros. The screening age is 45, not 50. Dr. Madhav Danthala provides treatment planning, chemotherapy, targeted therapy, and immunotherapy at Omega Hospitals, Gachibowli, and Peoples Polyclinic, Manikonda.
What is Colorectal Cancer?
Colon and rectal cancers arise from the lining of the bowel, most often from adenomatous polyps that grow over years. Modern treatment is shaped by molecular profile, not just stage.
MSI-high tumours
About 15% of colorectal cancers have defective DNA-repair (MSI-high). These respond exceptionally well to immunotherapy — often better than to chemotherapy alone.
KRAS, BRAF, HER2
Molecular markers shape targeted therapy choice. Every advanced colorectal cancer should be molecularly profiled at diagnosis.
When to See a Doctor
Most causes of these symptoms are benign. The pattern that matters is when something is new, persistent, or accompanied by other warning signs.
Blood in stool
Persistent or recurrent rectal bleeding, especially after age 45 or with other symptoms.
Change in bowel habit
New constipation or diarrhoea persisting more than three weeks, or the feeling of incomplete emptying.
Unexplained weight loss
More than 5 kg lost in a few months without dietary or activity change.
Iron-deficiency anaemia
Unexplained low haemoglobin in any adult — particularly men or post-menopausal women — should prompt colonoscopy.
Dr. Danthala's Approach
Colorectal cancer treatment in 2026 is increasingly molecularly guided.
Molecular profiling first
MSI status, KRAS, NRAS, BRAF, and HER2 are tested at diagnosis to guide therapy choice and identify candidates for immunotherapy.
More than one path
For rectal cancer, total neoadjuvant therapy and watch-and-wait protocols are increasingly defensible alternatives to immediate surgery in selected patients.
Clear, structured communication
Every consult ends with a written summary of the plan, expected timeline, and the trade-offs of each option.
Frequently Asked Questions
At what age should I start colonoscopy screening in India?
The recommended screening age was lowered from 50 to 45 in 2021 and has been adopted globally including in India. Young-onset colorectal cancer (under 50) is now the fastest-growing cancer in some Indian metros.
Does blood in stool always mean cancer?
No. The most common cause is haemorrhoids. However, persistent or recurrent blood — especially in anyone over 45, or with changes in bowel habits, weight loss, or anaemia — should be evaluated promptly.
What is MSI-high colon cancer?
MSI-high describes a tumour with defective DNA-repair machinery. About 15% of colon cancers are MSI-high. These respond exceptionally well to immunotherapy. MSI status should be tested in all colorectal cancers at diagnosis.
When should I start screening earlier than 45?
If a first-degree relative had colorectal cancer (start at 40 or 10 years before their diagnosis), with inflammatory bowel disease, previous adenomatous polyps, or hereditary syndromes like Lynch syndrome.
What does treatment usually involve?
Early-stage colon cancer: surgery, sometimes followed by chemotherapy. Rectal cancer: often combined chemoradiation followed by surgery. Advanced disease: chemotherapy plus targeted therapy or immunotherapy depending on molecular profile.
