STOMACH CANCER
Cancer starts when cells in the body begin to grow out of control. Cells in early any part of the body can become cancer. Stomach cancer, also called gastric cancer is a cancer that starts in the stomach. Stomach cancer should not be confused with other cancers that can occur in the abdomen, like cancer of the colon, liver, pancreas or small intestine because these cancers may have different symptoms, different outlooks, and different treatment.
The stomach is a sac-like organ that holds food and starts to digest it by secreting gastric juice. The food and gastric juice are mixed and then emptied into the first

As a cancer grows from the mucosa into deeper layers, the stage becomes more advanced and the prognosis is not good.
STOMACH CANCER
The different types of stomach cancers includes:
-Adenocarcinoma: These cancers develop from the cells that form the inner most lining of the stomach (mucosa). About 90% to 95% of cancers of the stomach are adenocarcinomas.
-Lymphomas: These are cancers of the immune system tissue that are sometimes found in the wall of the stomach. About 4% of stomach cancers are lymphomas.
-Gastointestinal stromal tumor (GIST): These are rare forms of cells in the wall of the stomach called Interstitial cells of Cajal. Some of these tumors are non-cancerous; others are cancerous. Although GISTs can be found anywhere in the digestive tract, most are found in the stomach.
-Carcinoid Tumor: These are tumors that start in hormone-making cells of the stomach. Most of these tumors do not spread to other organs. About 3% of stomach cancers are carcinoid tumors.
- Other types of cancer, such as squamous cell carcinoma, small cell carcinoma, and leiomyosarcoma, can also start in the stomach, but these cancers are very
Over 95% of colorectal cancers are ad enocarcinomas. These are cancers of the glandular cells that line the inside of the colon and rectum. Other, less common type of tumors may also develop in the colon and rectum. Carcinoid tumors develop from hormone-producing cells of the intestine. Gastrointestinal stromal tumors develop in the connective tissue
The stomach is an organ that is part of the digestive system. The stomach is located in the upper left part of the abdominal cavity, below the diaphragm and next to the liver (Stomach, 2013). The inner walls of the stomach contain small pores called gastric pits. The gastric pits contain cells that secrete chemicals that aid in the digestion of food (Nguyen, 2015). In this essay, I will discuss the different cell types of the stomach, how they work together to provide the overall function of the stomach, why each organ requires different cell types, why the stomach can’t be comprised of just one cell type, and the advantage of having different types of cells.
the American Cancer Society there are benign tumors, which are rare and often develop in
Yet another widespread type of this kind of most cancers is peritoneal mesothelioma. This kind of peritoneal membrane layer aids inside housing of the organs inside stomach. Though peritoneal mesotheliomas usually are much less widespread as compared to pleural mesotheliomas, they're additional unpleasant and may trim down living requirement of the patient. Mesotheliomas
Pancreatic Cancer Axia College (2009) Pancreatic cancer is an abnormal, uncontrolled growth of the cells in the pancreas, which is a digestive gland located behind the stomach. The pancreas is both an endocrine and exocrine gland. Cancer of the exocrine pancreas is more common than cancerof the endocrine pancreas. Pancreaticcancer is the fourth leading cause of cancer related deaths among men and women. Pancreatic cancer remains both a challenge to diagnose and even a greater challenge to treat effectively. What is the pancreas? The pancreas is a spongy, tube-shaped organ about six inches long. The pancreas is located in the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen. The
Cancer is a very general term that can refer to many different diseases. The different major classifications of cancer are Carcinoma, Leukemia, Myeloma, Lymphoma, and Sarcoma. Carcinoma is a cancer of the external or internal linings of the body such as epithelial tissue. Leukemia is a cancer of the bone marrow. This is also known as blood cancer, because bone marrow is the site where blood cells are produced. Myeloma is a cancer found specifically in the plasma cells of bone marrow. Lymphoma is a cancer that develops in the lymphatic system. The cancer appears in the nodes, glands,
Ther are many less common pathological types. These types including cystadenocarcinomas, pancreatoblastoma ,adenosquamous carcinomas, signet ring cell carcinomas, hepatoid carcinomas, colloid carcinomas, undifferentiated carcinomas, and undifferentiated carcinomas with osteoclast-like giant cells which account for 1% of pancreatic cancers, and they have a better prognosis than the other exocrine types (Tobias et al., 2010).
Stomach Cancer is cancer of the stomach which is also known as Gastric Cancer. It is a disease where malignant cells arise from the lining of the stomach which could eventually grow into a tumor found in the upper part of the abdomen and just below the ribs. Since the stomach is a part of the body’s digestive system, it produces acids and enzymes that break down food before passing through the small intestine which can cause the cancer to develop in any part of the stomach and spreads up towards the esophagus. The cancer happens over a period of a few years of bad acids being ate or inhaled which causes inflammation in your gut called gastritis, long-lasting anemia that continues to grow in the stomach that can also put you at a higher risk to get cancer. Although, not knowing exactly what makes stomach cancer cells, smoking, being overweight, exposure to coal, metal, timber industries all put you at a higher risk of receiving the cancer.
Cancer is a class of diseases characterized by out-of-control cell growth. Colon cancer forms when this uncontrolled cell growth happens in the cells of the large intestine. Most colon cancers originate from small, noncancerous (benign) tumors called adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps may grow into malignant colon cancers over time if they are not removed during colonoscopy - a procedure looking at the inner lining of the intestine. Colon cancer cells will invade and damage healthy tissue that is near the tumor, causing many complications. After malignant tumors form, the cancerous cells may travel through the blood and lymph systems, spreading to other parts of the body. These
About 10% to 20% of cancers that start in the liver are intrahepatic cholangiocarcinoma. These cancers start in the cells that line the small bile ducts (tubes that carry bile to the gallbladder) within the liver.
Who can get colon cancer? Everyone can get colon cancer but your risk of getting it increases after the age of 50 and increases even further after the age of 62. (American Cancer Society) According to the American Cancer Society 137,000 people have been diagnosed with colon cancer and 50,310 people have died from this disease in 2014. So what are the causes of colon cancer? About 70% of all cancer cases are based around the environment. (National cancer institute) As well as the environment your diet also plays a role in either preventing cancer or getting it. Many diets that are high in fat, red meat, calories, and a significant amount of alcohol consumption can lead to colon cancer. As for diets with high fiber
One of the leading causes of death in the world is cancer. There are various types of cancers but the one that will be discussed is gastric cancer, also referred to as stomach cancer. Gastric cancer is difficult to diagnose at an early stage due to the fact that the symptoms of the disease are quite similar to the symptoms of every day stomach issues such as indigestion, loss of appetite, and heart burn, just to name a few (Gastric Cancer Treatment 2015). In most cases, the cancer is not discovered until it is in a more advanced stage and as a result oncologists find it extremely difficult to cure it. Gastric cancer is a complex disease that is categorized in four different stages and that have many different treatments for it.
In pancreatic cancer, cancer cells in the pancreas grow and multiply quickly, which can cause a tumor to grow. In stage 4 pancreatic cancer, a cancerous tumor has begun in the pancreas and has spread beyond the pancreas into parts of the body far from the pancreas. It may also have spread to the lymph nodes and the organs and tissues found near the pancreas. The effect of this tumor on the body depends on where the tumor is, how it has spread, and how large it is. If the tumor blocks the flow of bile, which is produced in the
Stomach cancer, also known as gastric cancer, is a type of cancer that develops slowly over many years. Most frequently, stomach cancer starts in the lining of the stomach otherwise knows as the mucosa, and then develops into the other layers of the stomach. There are many ways in which stomach cancer spreads. In some cases it invades near by organs or it can also travel through the bloodstream to for cancer in other organs. There are many statistics and organizations of support for stomach cancer, as well as, symptoms, risk factors, screening and diagnosis’ and, treatments. Like all cancers, stomach cancer is a deathly disease and one of the major leading causes of cancer deaths in countries other than the U.S.
It is called malignant because not only can it invade into adjacent organs but unfortunately a cancer can spread to other tissues and that can be life threatening. Cancer can actually occur anywhere in the body because there are cells everywhere in the body. In women, one of the most common cancers of course is breast cancer, in men prostate cancer and in men and women, lung cancer and colon cancer are common cancers. It is important to understand that the cancer that occurs in one individual is very different from the cancer that occurs in another. Everyone is different; a lung tumor in one person will be different from a lung tumor in another person. Once a diagnosis of cancer is made, the next obvious question is what do you do? There are several things that are really relevant, for example, the stage of the cancer which is information about where is the cancer? You say it’s a particular kind of cancer? How much cancer is present? Has is spread? Is it in lymph nodes? Has it spread to other organs of the body? Cancer affects everyone in one way or another. Whether it is a family member, loved one or ourselves, cancer has touched our lives.
