Have you been experiencing frequent stomach pain, unexplained weight loss, changes in bowel habits, or digestive problems that simply won’t go away? Perhaps you have been blaming these symptoms on unhealthy eating habits, stress, acidity, or your busy lifestyle.
While many digestive issues are caused by common gastrointestinal conditions, persistent symptoms can sometimes indicate something more serious, including stomach cancer or colon cancer.
One of the biggest challenges with digestive cancers is that they may not cause noticeable symptoms during their early stages. This makes it important to pay attention to unusual changes in your body and seek medical advice when something doesn’t feel right.
At Apollo Hospitals, Delhi, Dr. Asit Arora, Oncologist, provides specialist consultation for individuals seeking evaluation and treatment for stomach cancer, colon cancer, and other gastrointestinal cancers. Understanding the warning signs is an important first step towards timely diagnosis and appropriate care.
What Are Stomach Cancer and Colon Cancer?
Stomach cancer, also known as gastric cancer, develops when abnormal cells grow uncontrollably in the inner lining of the stomach. As the disease progresses, it may affect the stomach’s ability to digest food and cause symptoms such as abdominal discomfort, reduced appetite, and unexplained weight loss.
Colon cancer develops when abnormal cells grow in the colon or large intestine. In some cases, it begins as small growths called polyps, which may gradually develop into cancer over time. Colorectal cancer can affect the colon or rectum and may cause changes in bowel habits, rectal bleeding, and abdominal discomfort.
According to GLOBOCAN 2022 estimates, India recorded approximately 43,060 new stomach cancer cases and 43,360 new colorectal cancer cases among men. These figures highlight the importance of cancer awareness, timely medical evaluation, and appropriate screening.
Early Signs of Stomach Cancer You Should Never Ignore
Stomach cancer can be difficult to identify during its early stages because its symptoms may resemble common digestive problems, such as acidity, bloating, or indigestion.
However, certain persistent symptoms deserve medical attention.
Common warning signs include:
- Frequent Indigestion: Regular discomfort, bloating, or a burning sensation after meals.
- Feeling Full Quickly: Experiencing fullness even after eating a small amount of food.
- Unexplained Weight Loss: Losing weight without making changes to your diet or exercise routine.
- Loss of Appetite: Not feeling hungry or noticing a significant change in eating habits.
- Persistent Stomach Pain: Experiencing abdominal discomfort or pain that does not improve.
- Repeated Nausea or Vomiting: Frequent episodes of nausea or vomiting without an obvious explanation.
- Difficulty Swallowing: Feeling that food gets stuck while swallowing.
- Blood in Vomit or Black Stools: These may indicate bleeding in the digestive tract and require prompt medical evaluation.
Not every episode of acidity or stomach pain indicates cancer. However, if symptoms persist, become worse, or occur alongside unexplained weight loss, it is important to consult a healthcare professional.
What Are the Early Signs of Colon Cancer?
Colon cancer may develop without noticeable symptoms during its early stages. When symptoms do appear, they often involve changes in bowel habits or digestive health.
Some common warning signs include:
- Blood in the Stool: Bright red blood or unusually dark, black stools.
- Changes in Bowel Habits: Persistent constipation, diarrhoea, or alternating episodes of both.
- Incomplete Bowel Emptying: Frequently feeling that your bowel has not completely emptied after passing stool.
- Persistent Abdominal Discomfort: Regular cramps, gas, bloating, or stomach pain.
- Unusual Tiredness: Ongoing fatigue or weakness, sometimes associated with anaemia caused by slow blood loss.
- Unexplained Weight Loss: Losing weight without a clear reason.
These symptoms can also occur due to conditions such as piles, infections, irritable bowel syndrome, and other digestive disorders. A proper medical evaluation helps identify the underlying cause.
Why Do People Develop Stomach and Colon Cancer?
There is rarely a single reason behind the development of digestive cancers. Several lifestyle, genetic, and medical factors may increase a person’s risk.
Common risk factors for stomach cancer include:
- Helicobacter pylori (H. pylori) infection.
- Tobacco use.
- Frequent consumption of heavily salted or preserved foods.
- A family history of stomach cancer.
- Certain inherited genetic conditions.
- Chronic inflammation of the stomach lining.
Common risk factors for colon cancer include:
- Increasing age.
- Family history of colorectal cancer or colon polyps.
- A personal history of colorectal polyps.
- Inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis.
- Excessive alcohol consumption.
- Obesity and physical inactivity.
- Diets high in processed meat and certain unhealthy eating patterns.
Having one or more risk factors does not necessarily mean you will develop cancer. Similarly, people without recognised risk factors can also develop stomach or colon cancer.
How Are Stomach and Colon Cancer Diagnosed?
If you experience persistent symptoms or have risk factors associated with digestive cancers, your doctor may recommend specific investigations based on your medical history and clinical assessment.
The diagnostic process may include:
Your doctor will discuss your symptoms, family history, lifestyle, previous medical conditions, and any changes in your digestive health.
2. Blood Tests
Blood investigations may help identify anemia, nutritional deficiencies, or other abnormalities. However, blood tests alone cannot confirm or rule out stomach or colon cancer.
3. Upper GI Endoscopy
An endoscopy involves inserting a thin, flexible tube with a camera through the mouth to examine the oesophagus, stomach, and upper part of the digestive tract. A biopsy may be performed if abnormal tissue is identified.
4. Colonoscopy
A colonoscopy allows doctors to examine the inside of the colon and rectum using a flexible camera. During the procedure, certain polyps can be removed and suspicious tissue samples can be collected for further examination.
5. Imaging Tests
CT scans and other imaging investigations may help determine the location and extent of the disease when cancer is suspected or confirmed.
6. Biopsy and Further Investigations
A biopsy involves examining a small tissue sample under a microscope to determine whether cancer cells are present and identify the cancer type. Additional tests may be recommended to guide treatment decisions.
Timely diagnosis helps doctors understand the condition and develop an appropriate treatment strategy.
What Treatment Options Are Available for Stomach and Colon Cancer?
Treatment for stomach and colon cancer depends on several factors, including the type of cancer, its stage, location, spread, and the patient’s overall health.
Depending on the diagnosis, treatment options may include:
- Surgery: Involves removing the cancerous part of the stomach or colon, along with nearby lymph nodes when necessary.
- Chemotherapy: Uses specialised medicines to destroy cancer cells or slow their growth. It may be recommended before or after surgery or in advanced disease.
- Targeted Therapy: Uses medicines designed to act on specific proteins or genetic changes found in certain cancer cells.
- Immunotherapy: Helps the immune system recognise and attack cancer cells in selected patients.
- Radiation Therapy: Uses high-energy radiation to target cancer cells. It is commonly considered in certain rectal cancers and selected stomach cancer cases.
Not every patient requires all these treatments. Some individuals may benefit from surgery alone, while others may need a combination of therapies.
Your oncologist will explain the available options, expected benefits, possible side effects, and treatment goals before recommending an individualised care plan.
