Anemia is a condition marked by a deficiency of healthy red blood cells or hemoglobin, leading to fatigue, weakness, and pale skin. While anemia has many causes—such as nutritional deficiencies, chronic diseases, or blood loss—it can sometimes be an early warning sign of something more serious, such as stomach cancer.
At Action Cancer Hospital, the Department of Medical Oncology often encounters patients who initially present with unexplained anemia, which later turns out to be related to underlying gastrointestinal malignancies, including stomach cancer. Recognizing this link is essential for early diagnosis and effective treatment.
What Is Stomach Cancer?
Stomach cancer, also known as gastric cancer, develops in the lining of the stomach. It usually begins in the mucosa—the innermost layer—and gradually invades deeper layers over time. The disease often goes unnoticed in its early stages, as symptoms like indigestion, bloating, or mild discomfort are easily mistaken for common digestive issues.
However, as the cancer grows, it can interfere with the stomach’s ability to absorb nutrients or cause internal bleeding—leading to chronic anemia.
How Stomach Cancer Leads to Anemia
There are several ways stomach cancer can cause anemia, both directly and indirectly:
1. Chronic Blood Loss
One of the most common causes is slow internal bleeding from the tumor. The cancerous growth may erode blood vessels in the stomach lining, causing small but continuous bleeding that may not be visible in stool. Over time, this leads to iron-deficiency anemia.
2. Poor Iron Absorption
Stomach cancer can also interfere with the stomach’s ability to produce acid and digestive enzymes, which are essential for iron absorption. Reduced acid production (hypochlorhydria) prevents the conversion of dietary iron into a form the body can easily absorb.
3. Nutritional Deficiencies
Patients with advanced stomach cancer often experience loss of appetite, nausea, or difficulty eating, leading to deficiencies in iron, vitamin B12, and folate, all of which are critical for red blood cell production.
4. Chronic Inflammation and Cancer Metabolism
In cancer patients, the body’s inflammatory response can suppress bone marrow function, reducing red blood cell production. This type of anemia is called anemia of chronic disease, commonly seen in individuals undergoing Medical Oncology treatments such as chemotherapy.
Early Warning Signs: When to Get Checked
The overlap between symptoms of anemia and stomach cancer can make early diagnosis challenging. However, being aware of subtle signs can make a crucial difference.
Common Symptoms of Anemia:
-
Persistent fatigue or weakness
-
Shortness of breath
-
Pale or yellowish skin
-
Dizziness or lightheadedness
-
Rapid heartbeat
Symptoms That May Suggest Stomach Cancer:
-
Unexplained weight loss
-
Loss of appetite or early fullness after eating
-
Indigestion or heartburn that doesn’t go away
-
Black or tarry stools (a sign of internal bleeding)
-
Abdominal pain or discomfort
If you experience persistent anemia without an identifiable cause, it’s essential to undergo further evaluation, including gastrointestinal investigations such as endoscopy.
Diagnosis: Identifying the Root Cause
At Action Cancer Hospital, the diagnostic approach involves a combination of tests to determine both the presence of anemia and its underlying cause.
1. Blood Tests
-
Complete Blood Count (CBC): Measures hemoglobin, hematocrit, and red blood cell indices.
-
Iron Studies: To check for iron-deficiency anemia.
-
Vitamin B12 and Folate Tests: Identify nutritional deficiencies.
2. Endoscopy
A gastroscopy (upper endoscopy) allows doctors to visually examine the stomach lining and collect biopsies if any suspicious areas are found. This is a key test to confirm stomach cancer.
3. Imaging Studies
CT scans, MRI, or PET scans are used to determine the extent of cancer spread and help plan further treatment.
4. Biopsy and Histopathological Analysis
Tissue samples are analyzed under a microscope to confirm the presence and type of cancer cells.
The Role of Medical Oncology in Treatment
Once a diagnosis of stomach cancer is established, a multidisciplinary team—led by the Medical Oncology department at Action Cancer Hospital—creates a personalized treatment plan.
1. Chemotherapy
Chemotherapy helps destroy cancer cells, shrink tumors, and manage metastasis. It may be used before surgery (neoadjuvant) to reduce tumor size or after surgery (adjuvant) to prevent recurrence.
2. Targeted Therapy
In some patients, targeted drugs are used to block specific pathways that cancer cells use to grow and divide. These therapies are often combined with chemotherapy for better results.
3. Immunotherapy
Immunotherapy boosts the patient’s immune system to recognize and fight cancer cells more effectively. It has shown promising results in advanced or metastatic stomach cancer.
4. Supportive Care for Anemia
Managing anemia is a vital aspect of overall treatment. The oncology team may recommend:
-
Iron or vitamin supplementation (oral or IV)
-
Blood transfusions in severe cases
-
Erythropoietin-stimulating agents (ESAs) to boost red blood cell production
Through comprehensive Medical Oncology care, patients receive both cancer-directed therapy and supportive management for symptoms like anemia, ensuring improved quality of life during and after treatment.
Importance of Early Detection
The link between anemia and stomach cancer underscores the need for timely medical evaluation. Many patients ignore fatigue or attribute it to stress, but persistent anemia should never be overlooked.
Early diagnosis of stomach cancer greatly improves survival rates. When detected at an early stage, treatment options are more effective, and patients can maintain better overall health outcomes.
Regular health checkups, awareness of symptoms, and access to advanced diagnostic facilities—such as those available at Action Cancer Hospital—are key to detecting gastric malignancies early.
