Stomach cancer develops in the lining of the stomach. Also, known as Gastric cancer, it affects the elderly more than the adult. According to the American Cancer Society, about 6 of every 10 people diagnosed with stomach cancer each year are 65 or older. Also, the lifetime risk of developing stomach cancer is higher in men (about 1 in 101) than in women (about 1 in 155).Oncologist Dr Pankaj Kumar Pande, Director–Surgical Oncology, Max Super Speciality Hospital, Shalimar Bagh, Delhi explained that this form of cancer spreads through three main pathways: Direct spread, lymphatic spread, and bloodstream.1. Direct Spread: In its early stages, stomach cancer can invade nearby tissues and grow into the deeper layers of the stomach or spread to surrounding organs such as the oesophagus, liver, pancreas, or intestines.2. Lymphatic Spread: Cancer cells can travel through the lymphatic system. The most common areas affected are the regional lymph nodes near the stomach, particularly those around the liver and diaphragm.3. Bloodstream: "Cancer cells can enter the bloodstream and travel to distant parts of the body," which is a common route for stomach cancer to metastasize to distant organs.He further explained that cancerous cells spread from the original tumour to other parts of the body through a process called Metastasis. The most common sites for the spread are the liver, lymph nodes, peritoneum, lungs, bones, and ovaries. What Are the Early Warning Signs of Stomach Cancer?The early warning signs of stomach cancer are often subtle and can be easily overlooked. Some of the common early signs include:- Indigestion or Discomfort: Mild indigestion, bloating, or a feeling of fullness after eating can often be dismissed as normal but may indicate an early stage of stomach cancer.- Loss of Appetite: A lack of interest in food or feeling full quickly, which can be intermittently noticed and often attributed to stress or other non-cancer causes.- Unexplained Weight Loss: Losing weight without trying or experiencing an unexplained drop in appetite, which may signal cancer progression.- Abdominal Pain or Discomfort: Persistent or occasional pain in the stomach area, often after eating, can become more severe as the condition progresses.- Nausea or Vomiting: Nausea, sometimes accompanied by vomiting, may occur especially after meals and is linked to cancer blocking or irritating the stomach.- Heartburn or Acid Reflux: Persistent heartburn that doesn't respond to usual treatments could signal stomach cancer.Dr Pande notes that "In the early stages, these symptoms tend to be mild and intermittent," leading many to attribute them to less serious digestive issues. Unfortunately, this often results in the cancer being diagnosed at a more advanced stage.Recommended Lifestyle Changes After Cancer TreatmentAfter undergoing treatment for stomach cancer, adopting lifestyle and dietary changes can significantly improve recovery and reduce the risk of recurrence. Dr Pande advises patients to focus on a balanced diet, consisting of fruits, vegetables, whole grains, lean proteins, and fiber-rich foods, to aid digestion and overall health. "Eat small, frequent meals and stay hydrated with fluids like water or herbal teas," he recommends.As far a lifestyle alterations are concerned, he emphasizes the importance of regular physical activity, starting with light exercises to rebuild strength. He also suggests managing stress through relaxation techniques and prioritizing adequate sleep (7-9 hours a night) for effective healing. Additionally, regular check-ups and screenings are vital for ongoing monitoring.
