Stomach Cancer By: Amanda Cook
Bio 101
November 29, 2012 Introduction Stomach is a important organ of the digestive system.
When food is swallowed, it travels down the esophagus. (nutrients are absorbed)
Food enters stomach. (it is further digested into a liquid form)
The liquid moves into the small intestine. Stomach cancer is also known as gastric cancer
Forms when cells multiply at a uncontrollable, rapid rate
If left untreated, it can spread to lymph nodes, and even to the lung and ovaries Who Gets Stomach Cancer? Thesis Today I will be discussing...

Who can get stomach cancer
The causes and risk factors
Treatment The number of stomach cancer cases have decreased significantly in the past 60 years.

Between 1950 and 1980, the death rate decreased by:
59% in men
65% in women.

By the end of 2012, in the United States there will be:
21,320 cases of stomach cancer
15,070 people with die from it International Agency for Research on Cancer Study Done By Johns Hopkins University Treatment Surgery
Radiation therapy.
Most patients receive more than type of treatment. Surgery A patient either has a partial gastrectomy or total gastrectomy

Partial surgery is performed for tumors that are located at the lower part of the stomach

Total gastrectomy is performed for tumors that are located at the upper part of the stomach. partial full Chemotherapy Chemotherapy uses drugs to kill cancer cells

The drug is given through a vein

It can harm normal cells

People experience different types of side effects:
a higher chance of infections, bruises, or the feeling of weakness.
hair lost
poor appetite
vomiting Radiation Therapy Uses high-energy rays to kill cancer cells

Normal cells are also damaged.

Combined with chemotherapy to treat stomach cancer

People experience different side effects.
Nausea and diarrhea
Red, dry, tender, itchy skin
Make a person very tired Conclusion From my research on stomach cancer, I believe scientists and doctors will continue to focus mainly on Helicobacter pylori and how it causes stomach cancer, since the cause is not yet known.

I hope that by finding out more information about how H. pylori relates to stomach cancer, researchers can find a better way to prevent people will from developing stomach cancer. Work Cited ("Stomach Cancer.") ("Stomach Cancer.") There are different types of stomach cancer:
carcinoid cancer
gastrointestinal stormal tumor

90% to 95% of the cases are adenocarcinoma. ("Stomach Cancer.") adenocarcinoma originates in glandular cells, which are found in the lining of the stomach (A.D.A.M. Editorial) It is still the sixth most common cancer for both men and women in the world.

Japan has the highest rate of stomach cancer:
78 cases per 100,000
10 cases per 100,000 (United States)

Most people who get stomach cancer are over the age of 50. (Whitehouse, Michael) ("What Are the Key Statistics about Stomach Cancer?") (Whitehouse, Michael) ("Stomach Cancer.") Twice as many men get stomach cancer compared to women ("Stomach Cancer.") Cause and Risk Factors Doctors and scientists do not know the exact causes of stomach cancer.

They do know that people who have certain risk factors are more likely to develop stomach cancer.

A risk factor is anything that affects a person's chance of getting the disease like stomach cancer. ("Risk Factors.") Risk Factors: •Infection in the stomach by a bacteria called Helicobacter pylori


•Family history and heredity

•Being a male over 50 years old

•Pernicious anemia (low count of blood cells caused by lack of vitamin B12)

•Previous surgery to remove the end of the stomach for peptic ulcer disease

•Chronic gastritis (inflammation of the stomach)

•Adenomatous type of polyps


•Being over weight ("Gastric Cancer.") (RelayHealth) Helicobacter Pylori Infection with H. pylori bacteria seems to be a major cause of stomach cancer

Long-term infection can lead to inflammation and pre-cancerous changes in the lining of the stomach

Stomach cancer patients have a higher rate of H. pylori infection than people without cancer ("What Are the Risk Factors for Stomach Cancer?") H pylori infect the inner lining (mucosa) of the stomach

Analysis of 12 studies showed the risk of stomach cancer was six times higher for H. pylori-infected people than for uninfected people ("Risk Factors.") I am going to be focusing on: Helicobacter pylori (H. pylori)

Diet Diet Greatly linked to stomach cancer

High diet in foods that are smoked, salted, or pickled cause an increase risk It is thought to be that 70% to 90% of stomach cancer begins due to H. pylori (Wood-Moen, Robin.) Nitrates and nitrites:

found in cured meats, some drinking water, and vegetables

can be converted by H. pylori into compound that can cause stomach cancer ("What Are the Risk Factors for Stomach Cancer?") ("Risk Factors.") People who switched from a Japanese diet, which is high in sodium to an American diet had a decrease chance of getting stomach cancer (Cherath, Lata Roberts) ("Treatment.") ("Treatment.")
