Stomach cancer, also known as gastric cancer, is a serious health concern that affects thousands of individuals worldwide. It arises when cancerous cells form in the lining of the stomach and can spread to other parts of the body if left untreated. In India, stomach cancer is among the leading causes of cancer-related deaths, necessitating early detection and effective treatment. This blog aims to shed light on stomach cancer, its risk factors, symptoms, diagnosis, and the various treatment options available in India.
Understanding Stomach Cancer
Stomach cancer typically develops over time and is influenced by a combination of genetic, environmental, and lifestyle factors. Some of the risk factors associated with stomach cancer include:
Helicobacter pylori infection: A bacterial infection that causes inflammation and ulcers in the stomach lining, increasing the risk of cancer.
Age and gender: Stomach cancer is more common in people over the age of 50, and men tend to have a higher incidence of the disease compared to women.
Diet: Consuming a diet high in smoked, salted, or pickled foods, as well as low in fruits and vegetables, may increase the risk.
Family history: Individuals with a family history of stomach cancer or certain genetic conditions, such as hereditary diffuse gastric cancer (HDGC), are at higher risk.
Smoking and alcohol consumption: These lifestyle factors have been linked to an increased risk of stomach cancer.
Symptoms of Stomach Cancer
The early stages of stomach cancer may not present any noticeable symptoms, making early detection challenging. However, as the disease progresses, individuals may experience the following symptoms:
- Persistent indigestion or heartburn
- Abdominal pain or discomfort
- Loss of appetite and unintentional weight loss
- Feeling full after eating small amounts of food
- Nausea and vomiting
- Swelling in the abdomen
- Blood in the stool or black, tarry stools
Diagnosis of Stomach Cancer
Detecting stomach cancer at an early stage significantly improves the chances of successful treatment. The diagnostic process may involve:
Endoscopy: A thin, flexible tube with a camera (endoscope) is inserted through the mouth to examine the stomach lining and collect tissue samples for biopsy.
Imaging tests: CT scans, MRIs, and PET scans may be used to assess the extent of cancer spread and identify potential metastases.
Biopsy: A tissue sample collected during endoscopy is examined under a microscope to confirm the presence of cancerous cells and determine the cancer's stage and type.
Blood tests: Certain blood markers may be elevated in cases of stomach cancer, helping in the diagnostic process.
Treatment of Stomach Cancer in India
India has made significant advancements in cancer care, offering a wide array of treatment options for stomach cancer patients. The most suitable treatment plan depends on factors such as the stage of cancer, the patient's overall health, and the presence of any underlying medical conditions. The primary treatment modalities for stomach cancer in India include:
Surgery: Surgery is the mainstay of treatment for early-stage stomach cancer. Depending on the tumor's size and location, surgeons may perform subtotal or total gastrectomy (partial or complete removal of the stomach), along with lymph node dissection to remove potentially cancerous lymph nodes.
Chemotherapy: Chemotherapy involves the use of powerful medications to kill cancer cells or stop their growth. It may be administered before surgery (neoadjuvant chemotherapy) to shrink the tumor or after surgery (adjuvant chemotherapy) to reduce the risk of cancer recurrence.
Radiation therapy: Radiation therapy uses high-energy X-rays or other particles to target and destroy cancer cells. It may be combined with chemotherapy as a part of the treatment plan.
Targeted therapy: Targeted therapies specifically target certain proteins or genetic mutations present in cancer cells, effectively blocking their growth and spread.
Immunotherapy: Immunotherapy harnesses the body's immune system to recognize and attack cancer cells. It has shown promising results in treating advanced or metastatic stomach cancer.
Palliative care: Palliative care focuses on alleviating symptoms and improving the quality of life for patients with advanced stomach cancer. It aims to manage pain, provide emotional support, and address other issues to enhance overall well-being.
Conclusion
Stomach cancer is a significant health concern, but early detection and access to effective treatments can significantly improve patient outcomes. India has emerged as a leading destination for advanced cancer care, with its world-class hospitals and highly skilled medical professionals offering a range of treatment options. By promoting awareness, encouraging regular health check-ups, and leveraging the latest medical advancements, India is making significant strides in the battle against stomach cancer, providing hope and improved quality of life for patients and their families.
