Introduction to Stomach Cancer
Stomach cancer is a type of malignancy that affects the stomach, which is a vital organ responsible for digesting food. The stomach is a sac-like structure located in the upper abdomen, and it plays a crucial role in breaking down food into smaller molecules that can be absorbed by the body. Stomach cancer occurs when abnormal cells in the stomach lining grow and multiply uncontrollably, forming a tumor. If left untreated, the tumor can invade surrounding tissues and spread to other parts of the body, such as the lymph nodes, liver, and lungs.
Types of Stomach Cancer
There are several types of stomach cancer, each with distinct characteristics and prognoses. The most common types of stomach cancer include:
Adenocarcinoma, which accounts for approximately 90% of all stomach cancer cases. This type of cancer originates in the glandular cells of the stomach lining.
Lymphoma, which is a type of cancer that affects the immune system and can occur in the stomach.
Gastrointestinal stromal tumor (GIST), which is a rare type of tumor that arises in the connective tissue of the stomach.
The Biggest Symptom of Stomach Cancer
The biggest symptom of stomach cancer is abdominal pain or discomfort. This symptom can manifest in different ways, such as a dull ache, a sharp pain, or a feeling of fullness or bloating in the upper abdomen. The pain or discomfort may be constant or intermittent and can worsen over time. In some cases, the pain may radiate to the back or chest, making it difficult to breathe or swallow.
