How What is Stomach Cancer affect the body? Explained Uncontrolled cell growth in the gastric lining can lead to serious health issues. This condition, often referred to as stomach cancer, starts in the inner layer of the stomach. Over time, tumors may form, disrupting normal digestive functions and nutrient absorption.
When left untreated, these abnormal cells can spread to other organs. This process, known as metastasis, occurs through the lymphatic system or bloodstream. Common areas affected include the liver, making early detection crucial for effective treatment.
The stomach plays a vital role in breaking down food and processing nutrients. Any disruption to this system can lead to significant health challenges. Recognizing vague symptoms early can improve outcomes and provide better management options.
Understanding Stomach Cancer
Gastric cancer begins in the mucus-producing cells of the stomach lining. Over time, these abnormal cells can grow uncontrollably, forming tumors. This process often starts in the inner layers and may spread deeper into the stomach wall.
Origins of Adenocarcinoma
Most cases, about 95%, are adenocarcinomas. These develop in the mucus-producing cells of the stomach lining. Two main types exist: intestinal and diffuse. Intestinal grows more slowly, while diffuse spreads rapidly.
Role of H. pylori
Chronic inflammation caused by H. pylori infection damages the protective lining. This creates an environment where abnormal cells can thrive. Over time, this damage increases the risk of tumor formation.
Genetic Mutations
DNA mutations disrupt normal cell life cycles. These changes trigger uncontrolled growth, leading to the development of cancer cells. Genetic factors can also play a role in this process.
Tumor Formation
Tumors often start in the mucosa, the stomach’s inner layer. As they grow, they can invade deeper layers, including the muscle. This progression can lead to more severe health issues.
- Adenocarcinoma origins: Begins in mucus-producing cells.
- H. pylori’s impact: Damages the protective lining, increasing risk.
- Genetic mutations: Disrupt normal cell growth cycles.
- Tumor formation: Starts in mucosa, spreads to muscle layers.
- Growth patterns: Intestinal vs diffuse adenocarcinoma.
