Stomach and Colorectal Cancer Treatment in Varanasi: A Family Guide

Acidity, a heavy stomach, loose motions or a little blood in the stool are so common that most of us ignore them. Usually they are harmless. But when such problems keep coming back for weeks, or appear along with weight loss and weakness, they deserve a proper check. Cancers of the stomach, colon and rectum are among the digestive cancers seen regularly in Purvanchal, and they are often found late because early signs feel ordinary.

This guide is for patients and families who want to understand these cancers in simple words: what to watch for, which tests are done, how staging works, and what treatment looks like. At ZenHeal Cancer Hospital in Varanasi, a dedicated digestive cancer team handles diagnosis, surgery, chemotherapy and long-term follow-up for patients from Varanasi, Chandauli, Ghazipur, Jaunpur and nearby districts.

Treatment always depends on the exact type and stage of cancer, and it is decided by your oncologist after a full review. Use this article to prepare questions, not to make decisions on your own.

Warning signs in the stomach and bowel

Stomach (gastric) cancer

• Indigestion or burning that does not settle with usual medicines
• Feeling full after eating only a little
• Loss of appetite and unexplained weight loss
• Repeated vomiting, sometimes with blood
• Black, tarry stools, which can mean bleeding higher up in the gut
• Tiredness and breathlessness due to low haemoglobin (anaemia)

Colon and rectal (colorectal) cancer

• Blood in the stool or bleeding from the back passage
• A change in bowel habit lasting more than a few weeks, such as new constipation, loose motions or thinner stools
• A feeling that the bowel has not emptied fully
• Pain or a lump in the abdomen
• Anaemia without a clear reason, especially in older adults

Many people assume rectal bleeding is due to piles. Piles are indeed common, but the two can look similar. A doctor should examine anyone with ongoing bleeding, especially after the age of 40 or if there is a family history of bowel cancer.

Tests that confirm the diagnosis

Upper GI endoscopy

For suspected stomach cancer, an endoscopy is the key test. A thin flexible tube with a camera is passed through the mouth into the food pipe and stomach. A spray numbs the throat and mild sedation may be given. If the doctor sees an abnormal area, small tissue samples (biopsies) are taken.

Colonoscopy

For the colon and rectum, a colonoscopy lets the doctor look at the full large bowel. The bowel must be cleaned the day before with a prescribed liquid, which means several trips to the toilet. Follow the preparation instructions closely, because a poorly cleaned bowel can hide small lesions and the test may need to be repeated.

Biopsy

Only a biopsy can confirm cancer. The pathologist reports the cell type, and sometimes extra tests are done on the tissue that help choose medicines later.

CT scan and other tests

A contrast CT scan of the chest, abdomen and pelvis shows whether the cancer has spread to lymph nodes, the liver, lungs or the lining of the abdomen. For rectal cancer, an MRI of the pelvis is often advised to see exactly how deep the tumour has grown. Blood tests, including a tumour marker called CEA for colorectal cancer, give a baseline for follow-up.

Understanding staging

Staging describes how far the cancer has grown and spread. It is the single most important factor in planning treatment.

Early detection improves treatment options. Even in locally advanced disease, a combination of chemotherapy and cancer surgery is often planned with the aim of controlling the disease well. In advanced disease, treatment focuses on controlling the cancer, relieving symptoms and protecting quality of life.

Surgery for stomach, colon and rectal cancer

Surgery is the main treatment for many of these cancers when the disease can be removed completely. At ZenHeal Varanasi, these operations are led by Dr Pritesh Rajeev Singh, a surgical oncologist with 15 years of experience. He holds an MBBS, MS and MCh in Surgical Oncology from Dr B Borooah Cancer Institute, Guwahati, and his interests include GI, colorectal, stomach and oesophageal cancer surgery, lymph node dissection and locally advanced cancers. See Dr Pritesh Rajeev Singh's profile for details.

Gastrectomy

For stomach cancer, part of the stomach (partial gastrectomy) or the whole stomach (total gastrectomy) is removed along with nearby lymph nodes. The remaining gut is joined so food can pass. Patients learn to eat smaller, more frequent meals afterwards.

Colectomy and rectal surgery

For colon cancer, the affected segment of bowel and its lymph nodes are removed and the ends are joined. Rectal cancer surgery is more delicate because the rectum lies deep in the pelvis near the bladder, nerves and the muscles that control stool. Depending on the tumour's position, the surgeon may be able to join the bowel, or may create a stoma, either temporary or permanent.

Anaesthesia and recovery

Anaesthesia for major cancer surgery is led by Dr Maithili Thakur, an anaesthesiologist and critical care expert with more than 14 years of experience. After surgery, patients who need close monitoring can be cared for in the hospital's 10-bed ICU. Most patients start sips of fluid and walking early, as advised by the team, which helps recovery.

Chemotherapy and the role of radiation

Chemotherapy uses medicines that kill fast-dividing cancer cells. For stomach cancer, it is often given both before and after surgery. For colon cancer, it is commonly given after surgery if the cancer had reached lymph nodes or had other higher-risk features. In advanced disease, chemotherapy, sometimes with targeted medicines, helps control the cancer and symptoms.

ZenHeal Varanasi has a day-care unit where many chemotherapy cycles are given without an overnight stay. The team also manages side effects such as nausea, mouth sores, loose motions, tingling in the fingers and low blood counts.

For rectal cancer, radiation (radiotherapy), often combined with chemotherapy, may be advised before surgery to shrink the tumour. When radiotherapy is needed, the Varanasi team coordinates it with the ZenHeal hospital in Prayagraj, where radiation oncology is delivered.

Living with a stoma: the basics

A stoma is an opening on the belly through which stool comes out into a bag. A colostomy is made from the large bowel; an ileostomy from the small bowel. Hearing this can be upsetting, but many people live active lives with a stoma, and many stomas made during rectal surgery are temporary and closed later.

• Before surgery: the team marks the best site on your belly so the bag sits comfortably.
• Bag changes: you and one family member will be taught how to empty and change the bag before discharge.
• Skin care: clean the skin around the stoma with plain water and dry it gently. Red or sore skin often means the bag opening is cut too large.
• Diet: start with soft foods, chew well and add foods slowly. Some foods cause more gas or loose output.
• When to call: if the stoma turns dark or black, stops working with belly pain and vomiting, or bleeds heavily, contact the hospital at once.

Prayer, bathing and normal daily activities, including travel, are possible with a stoma. Ask the team about supplies and how to manage at religious gatherings or on long journeys.

Food and nutrition through treatment

Digestive cancers directly affect eating, so nutrition needs extra attention.

• Eat small meals every two to three hours instead of three large meals, especially after stomach surgery.
• Include protein at every meal: dal, paneer, curd, eggs, soya, chicken or fish as per your diet.
• Soft khichdi, dalia, suji upma and well-cooked vegetables are usually easy to digest.
• Drink fluids between meals rather than with meals if you feel full quickly.
• During loose motions, take oral rehydration solution and avoid very spicy or oily food.
• Do not start herbal powders or supplements without telling your oncologist, as some interact with chemotherapy.

Weigh yourself every week and tell the team if you lose weight steadily.

Follow-up after treatment

Once active treatment ends, regular check-ups help spot any return of the disease early and manage long-term effects. ZenHeal Varanasi offers structured follow-up for five years. Visits are more frequent in the first two years and spaced out later. They usually include an examination, blood tests such as CEA where relevant, periodic CT scans, and colonoscopy or endoscopy at intervals your doctor recommends.

Family members of people with bowel cancer may also be advised to start screening earlier. Ask your oncologist what applies to your family.

How ZenHeal can help

Families choose ZenHeal because it is a cancer-only hospital where the surgeon, chemotherapy team, anaesthesia and ICU team, and counsellors work together on digestive cancers. We believe this makes it the best cancer hospital in Varanasi for people who want their stomach or bowel cancer care handled in one place, about 4 km from BHU and easy to reach from Chandauli and Ghazipur. A counsellor reviews your reports, books appointments and gives a clear estimate. Financial help through the NGO Love Heals Cancer may be available for eligible patients, and the counsellor will check whether your scheme or insurance applies.

Frequently asked questions

Is blood in the stool always a sign of cancer?

No. Piles and fissures are much more common causes. But because the symptoms can look alike, ongoing bleeding should always be checked by a doctor, and a colonoscopy may be advised.

Is colonoscopy uncomfortable?

Most people find the bowel preparation the hardest part. During the procedure, sedation is usually given, and many patients remember little of it. Some bloating afterwards is normal and settles within hours.

Will I definitely need a stoma after rectal cancer surgery?

Not always. It depends on how close the tumour is to the anal opening and on how the bowel heals. Many stomas are temporary and closed after a few months. Your surgeon will explain your situation before the operation.

Can I eat normally after stomach removal?

Most people return to a fairly normal diet over time, but with smaller and more frequent meals. Some need vitamin B12 injections and iron supplements long term. Your treating team will guide you as you adjust.

Does chemotherapy for bowel cancer always cause hair loss?

Not always. Several medicines commonly used for colorectal cancer cause only mild hair thinning. Your oncologist will tell you what to expect from your specific regimen.

How often should I come for check-ups after treatment?

Usually every three to six months in the first two years, then less often up to five years. The exact schedule depends on your stage and treatment.
