Stomach Cancer Survival RatesThursday, February 5th, 2009
The prognosis and stomach cancer survival rates depend on the type of Stomach Cancer as there are different types like Adenocarcinomas which is the most common type and Lymphomas which are not so common.
Stomach Cancer Survival Rates By Stage
The stage of the cancer is important as it indicates the size and spread of the tumor. The grade of the cancer cells indicate how aggressive the cancer cells are, in general the lower the grade of the cancer cells, the better will be the stomach cancer survival rates of the individual.
Stomach cancer causes 1 million deaths annually worldwide. It is the 4th most common cancer in the world and the 2nd most common for cancer related deaths after lung cancer.
Stomach Cancer Survival Rates: Cancer Definition
Stomach cancer is also called gastric cancer. It occurs slowly over a number of years. It is preceded by pre cancerous changes in the lining of the stomach that rarely produce any symptoms until in the advanced stage. Diagnosis is thus delayed and stomach cancer survival rates are consequently not good.
Treatment is threefold and depends on the stage of cancer at the time of diagnosis. Surgically most of the tumor is removed and then chemotherapy and radiation therapy are given to control the spread of the cancer and extend the survival rate. Complete cures are not a common occurrence.
Worldwide Stomach Cancer Survival Rates
The overall 5 year stomach cancer survival rate is 20%, which means only 1 in 5 will survive 5 years. However, if the cancer is localized, if it has not spread to the lymph nodes, at least 75% of patients survive for 5 years and eventually two thirds of these survivors are cured.
Stomach cancer survival rates based on the stages of the cancer give an overall 70% for 5 years. Unfortunately, only 1 % of all cases are detected at this stage. 6% of cases are detected at stage 2 and their 5 year survival rate is 42%. A reasonable number of patients are diagnosed at stage 3 and their survival rate is 20% for 5 years. An overwhelming majority of 80% Stomach Cancer cases is detected at stage 4 and their 5 year stomach cancer survival rates at this very advanced stage is barely 5%.
