What Is Gastrointestinal (GI) Cancer?

GI (gastrointestinal) Cancers occur when abnormal cells in one or more parts of the digestive system grow uncontrollably. It is contingent upon the organ in question . The type of cancer . Common examples are stomach cancer, colorectal cancer, esophageal cancer, pancreatic cancer and liver cancer.

The symptoms, risk factors and treatment options can vary for each type. Some gastrointestinal cancers may not have clear symptoms in the early stages, so it’s important to be aware of any persistent or unusual changes in your digestive health.

What are the signs of gastrointestinal cancers?

Symptoms of gastrointestinal cancers vary with the affected organ, the size of the tumor and the stage of the disease. Some common warning signs are:

1. Unremitting abdominal pain or discomfort

Persistent abdominal pain, cramping or discomfort may be associated with a number of digestive conditions including gastrointestinal cancers. The pain may come after a meal, in a specific area of the abdomen, or for no obvious reason.

Most of the time, abdominal pain is caused by something other than cancer. However, persistent or unexplained abdominal pain should be checked out by a medical professional.

3. Unintentional Weight Loss

Unintentional loss of weight without modification in the diet, physical activity, or food habits could mean that you are suffering from an existing medical condition. Gastrointestinal malignancies can cause alteration in appetite, digestion, or nutrient absorption which results in loss of weight.

4. Changes in bowel habits

Unrelenting diarrhea, constipation, narrowing of stool, or changes in bowel movements could mean that something is wrong with your digestive system. These symptoms are often seen in individuals suffering from colorectal malignancies particularly if there is pain in the abdomen or presence of blood in the stool.

5. Bleeding in your vomit or stool

Blood in the stool can make the stool look dark and tarry or bright red. You can vomit blood in some upper digestive tract conditions. Many things can cause these symptoms, but you should never ignore them.

Vomiting blood, passing large amounts of blood or having black stools with dizziness or weakness needs urgent medical attention.

6. Trouble swallowing

If you keep having the sensation of food sticking when you swallow, or you have pain when you swallow, this can be a sign of cancer of the esophagus. Some people find it hard to swallow solid foods initially, and it gets worse over time.

If you find that swallowing is getting progressively more difficult, you should seek a medical assessment promptly.

7. Indigestion or ongoing bloating or feeling full quickly

Stomach or other gastrointestinal cancers in the stomach can cause frequent indigestion, unexplained bloating, nausea or feeling full after eating only small amounts of food. These symptoms are also frequently observed in many benign digestive diseases.

But persistent symptoms, especially those with decreased appetite or weight loss, should be evaluated by a doctor.

8. Tiredness and weakness

Ongoing tiredness or weakness. Gastrointestinal cancers can cause internal blood loss, or lead to anemia. Others may have low energy levels because they do not consume a lot or have a bad diet.

If you’re experiencing unexplained fatigue that lasts after a good night’s sleep, speak to your health care professional.

What are the risk factors and common causes of cancers of the gastrointestinal tract?

Gastrointestinal cancers are caused, like all cancers, by a complex series of interactions between genetics and environment. Such cancers are usually caused by a combination of genetic changes, exposure to environmental factors, lifestyle habits and in some cases existing health conditions.

1. Use of Alcohol and Tobacco Use

Tobacco use raises the risk of several cancers, including cancer of the esophagus, stomach, liver, and colon and rectum. Alcohol consumption is also associated with increased risk of some cancers of the gastrointestinal tract, particularly cancers of the esophagus, liver and colorectum.

Cancer risk can be reduced by avoiding tobacco and limiting or avoiding alcohol.

2. Poor diet and overweight

High consumption of processed meat, frequent consumption of red meat and a low intake of foods rich in fiber may increase the risk of colorectal cancer. Overweight and obesity are also associated with increased risk of a number of cancers, including colorectal cancer and esophageal adenocarcinoma.

Eating a diet high in vegetables, fruits, whole grains and other healthful foods and being physically active regularly helps improve general digestive health.

3. Chronic infections and inflammation

Some chronic infections and inflammations are linked with higher chances of developing some GI cancers.

H. pylori infection may lead to stomach cancer while chronic infections with hepatitis B and C are linked with the risk of developing liver cancer. Patients who suffer from chronic inflammatory bowel disorders, such as ulcerative colitis or Crohn’s disease, may have an increased chance of developing colorectal cancer.

Proper medical treatment will minimize these risks.

4. Genetic and family history factors

People who have a close relative with certain gastrointestinal cancers may be at increased risk, especially if cancer occurs at a young age or in more than one family member.

Hereditary syndromes such as Lynch syndrome and familial adenomatous polyposis can considerably increase the risk of colorectal cancer. If you have a strong family history, you might consider talking to your doctor about genetic counseling and earlier or more frequent screening.

5. Age and Pre-existing Medical Conditions

Many gastro-intestinal cancers risk increases with age. Other conditions, such as Barrett's esophagus, cirrhosis of the liver and some stomach or intestinal abnormalities can also increase the risk of certain cancers.

Having a risk factor doesn't mean that a person will necessarily get cancer. Similarly, people with gastrointestinal cancer may have no known risk factors.

How Are Cancers of the GI System Diagnosed?

Diagnosis starts with a medical history, assessment of symptoms and physical examination. Depending on the suspected cancer, the doctor may suggest blood tests, stool tests, imaging studies, endoscopy or colonoscopy.

Often, a biopsy (examination of a small sample of tissue in a laboratory) is required to confirm the diagnosis. More tests can help determine the stage of the cancer and help with treatment decisions.

The appropriate tests depend on the person's symptoms, medical history and the organ involvement that is suspected .

How to Reduce Your Risk of Gastrointestinal Cancers?

While some gastrointestinal cancers are preventable, the following habits may reduce risk:

• Avoid tobacco and limit or avoid alcohol.

• Exercise often and keep a healthy weight.

• Eat a well-rounded diet with plenty of vegetables, fruits, and whole grains.

• Talk to your doctor about recommended colorectal cancer screening.

• If symptoms persist please consult a medical professional

• Be evaluated and treated for relevant chronic conditions and infections.

• If you have a family history of gastrointestinal cancer, discuss genetic counseling or screening at a younger age.

Screening recommendations vary by age, personal history, family history and local clinical guidelines.

When to consult a doctor?

Don’t ignore persistent abdominal pain, unexplained weight loss, blood in the stool, changes in bowel habits, difficulty swallowing or persistent digestive discomfort. Having these symptoms does not mean you have cancer, but an early assessment can help to find out the cause.
