Understanding Stomach Cancer: Types, Symptoms, and Treatment Procedures
What is Stomach Cancer?
Stomach cancer, also known as gastric cancer, begins in the cells lining the stomach. It can develop in various parts of the stomach and spread to nearby organs if left untreated. This cancer often progresses without noticeable symptoms in the early stages, making early detection challenging. Kingsway Hospital in Nagpur provides comprehensive diagnostic and treatment options to manage stomach cancer, aiming for the best outcomes through personalized care.
Types of Stomach Cancer
Stomach cancer can be classified into different types based on where it originates and its cellular characteristics:
- Adenocarcinoma: The most common form of stomach cancer, originating in the cells that line the stomach and produce mucus and other fluids.
- Lymphoma: Cancer that begins in the lymphatic tissue, which can be present in the stomach.
- Gastrointestinal Stromal Tumors (GISTs): Tumors that begin in the connective tissue of the stomach, often affecting the muscle layer.
- Carcinoid Tumors: Rare tumors that originate from hormone-producing cells in the stomach lining.
Risk Factors
Several factors can increase the risk of stomach cancer:
- Age: People over 50 are at a higher risk.
- Gender: Men are more likely to develop stomach cancer than women.
- Family History: A family history of stomach cancer or certain genetic conditions (such as hereditary diffuse gastric cancer) increases the risk.
- Helicobacter pylori Infection: A bacterial infection that causes chronic inflammation in the stomach and increases the risk of cancer.
- Diet: Diets high in smoked, salted, or pickled foods and low in fruits and vegetables may increase the risk.
- Tobacco and Alcohol Use: Smoking and heavy drinking are known risk factors.
- Obesity: Being overweight increases the risk of developing stomach cancer.
Symptoms of Stomach Cancer
Early-stage stomach cancer often doesn’t cause symptoms, which makes early detection difficult. As the cancer progresses, symptoms may include:
- Abdominal Pain or Discomfort: Persistent or unexplained pain in the upper abdomen.
- Bloating and Fullness: Feeling bloated or full even after eating small amounts of food.
- Nausea and Vomiting: Vomiting, especially with blood or material that looks like coffee grounds.
- Unexplained Weight Loss: Sudden and significant weight loss without a clear cause.
- Difficulty Swallowing: A feeling of food getting stuck in the throat or chest.
- Fatigue and Weakness: Feeling unusually tired or weak.
- Blood in Stool or Vomit: Visible blood in the stool or vomiting may indicate advanced stages of stomach cancer.
Diagnosis of Stomach Cancer
At Kingsway Hospital in Nagpur, a range of diagnostic tests are used to confirm the presence of stomach cancer:
- Endoscopy: A thin, flexible tube with a camera (endoscope) is inserted through the mouth to examine the stomach lining and take tissue samples for biopsy.
- Biopsy: Tissue samples taken during endoscopy are examined under a microscope to confirm cancer.
- Imaging Tests: CT scans, MRI, and PET scans help determine the size and spread of the tumor.
- Upper GI Series (Barium Swallow): A special X-ray examination that provides images of the stomach and upper part of the intestines.
- Blood Tests: While not specific for stomach cancer, blood tests can provide information about overall health and detect anemia, which can result from bleeding in the stomach.
Stages of Stomach Cancer
Staging is critical for determining the most appropriate treatment. The stages of stomach cancer are as follows:
- Stage I: Cancer is localized within the stomach and has not spread to lymph nodes.
- Stage II: Cancer has spread to nearby tissues or lymph nodes.
- Stage III: Cancer has spread to nearby structures, such as the esophagus, liver, or other organs.
- Stage IV: Cancer has spread to distant parts of the body, such as the liver, lungs, or distant lymph nodes.
Treatment Options for Stomach Cancer
The treatment approach for stomach cancer depends on the stage, type, and location of the cancer, as well as the patient’s overall health. Kingsway Hospital in Nagpur offers a range of advanced treatment options:
Surgery
Surgery is the most common treatment for early-stage stomach cancer:
- Subtotal Gastrectomy: Removal of part of the stomach, typically when the cancer is confined to one area.
- Total Gastrectomy: Removal of the entire stomach. The remaining part of the digestive system is then reconnected to the small intestine.
- Lymph Node Removal: Lymph nodes near the stomach may also be removed if cancer has spread to them.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells or stop their growth and may be recommended for more advanced stages:
- Neoadjuvant Chemotherapy: Given before surgery to shrink the tumor and make it easier to remove.
- Adjuvant Chemotherapy: Given after surgery to reduce the risk of recurrence.
- Palliative Chemotherapy: For advanced stomach cancer, chemotherapy may help manage symptoms and improve quality of life.
Radiation Therapy
Radiation therapy uses high-energy rays to target cancer cells. It may be used in combination with surgery or chemotherapy:
- External Beam Radiation Therapy: Delivered from outside the body, this therapy targets the tumor.
- Palliative Radiation Therapy: To reduce symptoms such as pain, bleeding, or blockage caused by the tumor.
Targeted Therapy
Targeted therapies focus on specific proteins or mutations in cancer cells to stop their growth. Targeted drugs can be used in combination with other treatments to improve outcomes, especially in advanced cases.
Immunotherapy
Immunotherapy is designed to enhance the body’s immune system to fight cancer. It may be an option for patients with specific biomarkers or advanced stomach cancer that has not responded to traditional treatments.
Supportive Care and Rehabilitation
Kingsway Hospital in Nagpur focuses on providing comprehensive supportive care to manage the symptoms of stomach cancer and improve the quality of life:
- Pain Management: Medications and techniques to alleviate pain, especially for patients with advanced disease.
- Nutritional Support: Specialized dietary counseling to manage weight loss and prevent malnutrition, especially after surgery or chemotherapy.
- Psychosocial Support: Emotional and mental health support for both patients and their families, helping them cope with the challenges of cancer treatment.
- Physical Therapy: Rehabilitation to help regain strength and mobility, especially after surgery or during recovery from chemotherapy.
Preventive Measures
While stomach cancer cannot always be prevented, several steps can help reduce the risk:
- Helicobacter pylori Treatment: Treating H. pylori infections early can reduce the risk of stomach cancer.
- Healthy Diet: A diet rich in fruits, vegetables, and whole grains, and low in processed and smoked foods can lower the risk.
- Avoid Smoking and Excess Alcohol Consumption: These habits increase the risk of stomach cancer and should be avoided.
- Regular Medical Check-ups: Early detection through screening and addressing symptoms promptly can improve the chances of successful treatment.
