Early Warning Symptoms of Stomach Cancer, Including Symptoms, Risk Factors, and When to See a Doctor
Stomach cancer, also referred to as gastric cancer, occurs when there is an abnormal growth of cells in the stomach lining. At an early stage of this disease, one is likely to experience symptoms that are usually mistaken for digestive complications.
Indigestion, bloating, appetite loss, or occasional stomach discomfort does not automatically mean that you have cancer. However, it should not be overlooked, especially if the symptoms keep recurring or persisting.
Knowing the warning signs of stomach cancer will assist in early diagnosis.
Stomach Cancer
Stomach cancer is characterized by the growth of cancerous tumors within the stomach due to the growth of abnormal cells in an uncontrolled manner.
It develops in various parts of the stomach, and symptoms will vary with where the cancer starts and at which stage the cancer is.
Sometimes at the early stage of cancer, there may be no symptoms at all.
What are some Early Symptoms of Stomach Cancer?
Some of the early signs of stomach cancer can mimic several other common GI disorders. They include the following:
1. Indigestion
Indigestion, or discomfort after eating, can be one of the symptoms requiring medical attention due to its persistence.
Indigestion is quite common, although its frequent occurrence should not be ignored.
2. Becoming Satiated Rapidly
Some individuals become satiated quickly when consuming even just a little bit of food.
This is known as early satiety and requires evaluation if it is a frequent occurrence along with other symptoms.
3. Unexplained Weight Loss
Unexplained weight loss, which can result from a variety of factors, is an issue that does not require any immediate action.
However, in combination with digestive symptoms, unexplained weight loss is a situation worth investigating.
4. Persistent Upper Abdomen Discomfort
There are various digestive diseases that cause pain, pressure, or discomfort in the upper abdomen.
Understanding the nature of the discomfort helps a physician to understand what kind of further investigation is required.
5. Nausea or Vomiting
Prolonged episodes of nausea or recurrent bouts of vomiting may suggest a problem with the stomach or other parts of the digestive system.
Vomiting of blood or anything that resembles coffee grounds is considered an emergency situation.
6. Difficulty in Swallowing
If a tumor forms around the upper part of the stomach, difficulty in swallowing becomes another common symptom of this illness.
7. Black or Tar-like Stools
Upper gastrointestinal bleeding may result in the appearance of black or tar-like stools.
Although there may be multiple reasons for gastrointestinal bleeding, this symptom should not be overlooked.
What are the Causes of Stomach Cancer?
There is no one definite cause for the development of stomach cancer. There are some risk factors that could possibly lead to stomach cancer.
Risk factors are such as:
Growing older
Family history of stomach cancer
Inherited genetic syndromes
Chronic stomach inflammation
Helicobacter pylori infection
Smoking
Diets rich in specific preserved and processed foods
The presence of a risk factor does not necessarily result in cancer development. However, cancer can occasionally develop in people who do not have any known risk factors.
When Should You See a Doctor?
It may be necessary to see a doctor if there are digestive symptoms that:
Persist for several weeks
Keep recurring
Slowly worsen
Are coupled with unexpected weight loss
