Gastric cancer

Gastric cancer, also known as stomach cancer, is any malignant tumor that arises from cells in any of the layers of the stomach.

Treatment characteristics

Some of the symptoms are;

Poor appetite and weight loss (without dieting)

Abdominal pain

Unspecified discomfort in the abdomen, feeling of fullness from any food, however small,  indigestion

Acidity or burning

Nausea and/or vomiting, with or without blood

Swelling or accumulation of fluid in the abdomen

Blood in stool

These are risk factors, among others, for this pathology:
Age and gender (usually patients between 55 and 70 years old and more men than women)
A diet too rich in salt (salted, pickled, smoked…)
Genetic predisposition from hereditary factors

There are different treatments depending on the stage of the disease.

In stages I to III the tumor is usually considered “resectable” and therefore operable. In these cases we will undergo a surgical intervention known as gastrectomy (with or without lymphadenectomy depending on the condition). This intervention consists of removing, totally or partially, the stomach and the possible affected areas (nodes or other parts of tissues). After this intervention, the use of chemotherapy and even radiotherapy can be considered as post-surgical therapies to try to eradicate the cancer.

In stage IV the tumour is considered “unresectable” and therefore the main treatment to fight it will be chemotherapy which can be combined with other drugs, surgery and radiotherapy.

The result varies depending on each patient, their physical condition and the tumour stage.

If we are in the first two phases, the probabilities of overcoming this disease are very high.

The probabilities of being clean of cancer diminish according to the stage so there will be cases in which our treatment is focused on maintaining a quality of life as satisfactory as possible.

This will depend on the stage in which the disease has been detected. Your recovery time may range from two to three months or more, depending on your individual case, your doctor may specify a longer period of time.


If you came to us in the early stages, you may be able to return home after a month or two, although you will have to maintain a close follow-up with your medical team (in your country or in ours) to check your progress.

You must bear in mind that the first five years after the initial treatments are the most critical in terms of relapses, but after this time, if the results of the control tests confirm it, we can say that we have overcome the disease.

The 5-year survival rate for people with stomach cancer is 31%. This statistic reflects the fact that most people are diagnosed when the cancer has already spread to other parts of the body.


If stomach cancer is found before it has spread, the 5-year survival rate is usually higher, but it depends on the stage of the cancer found during surgery. 


If the cancer is diagnosed and treated before it has spread from the stomach, the 5-year survival rate is 67%. If the cancer has spread to nearby tissues or organs or to regional lymph nodes, the 5-year survival rate is 31%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 5%.
