Treatments for Stomach Cancer

Stomach cancer is a serious illness that affects the stomach, the organ in our body where food goes after we eat it. When someone has stomach cancer, abnormal and harmful cells start growing in their stomach, and can make them feel sick. 

Methods that are used to treat cancer under the supervision of various professionals include:

  • Medications
  • Chemotherapy 
  • Radiation therapy 
  • Targeted therapy 
  • Immunotherapy 
  • Surgical methods 

Let’s dive into a bit of detail for each of the treatment methods:

1. Chemotherapy: 

This treatment involves using special drugs to fight and kill cancer cells throughout the body. The drugs can be given either through pills or injections into a vein. Chemotherapy can be compared to a team of superheroes traveling through the bloodstream, seeking out and destroying the harmful cancer cells wherever they may be hiding.

2. Radiation Therapy: 

Radiation therapy uses high-energy beams, such as X-rays or protons, to target and kill cancer cells. It is a bit like shining a spotlight onto the affected areas to damage and destroy the cancer cells. Radiation therapy can be given externally, where a machine directs the beams towards the stomach, or internally, where radioactive material is placed inside the body near the cancer. Doctors carefully plan radiation therapy to avoid harming healthy cells as much as possible.

3. Targeted Therapy: 

This type of treatment attacks specific changes in cancer cells that allow them to grow uncontrollably. Different targeted therapy drugs work in different ways. They can interfere with the signals that tell cancer cells to divide, or they can block the growth of blood vessels that supply nutrients to the tumor. Targeted therapy is like using a specially designed missile that seeks out and destroys only the cancer cells while leaving healthy cells unharmed.

4. Immunotherapy: 

Our immune system helps protect us against diseases, including cancer. Immunotherapy works by strengthening the body’s own immune response to fight cancer cells. It is like having an army of soldiers who are trained to recognize and attack the cancer cells, helping the body’s natural defenses in the fight against the disease.

It’s important to remember that each person’s situation is unique, so doctors will create a treatment plan that is best for that individual. They will take into account things like the stage of the cancer, the patient’s overall health, and other important factors.

Surgical methods

When it comes to surgery methods used to treat stomach cancer, there are a few different options that doctors may consider. Let’s delve into each of them in a little more detail:

1. Endoscopic Resection: 

This is a minimally invasive procedure where the doctor uses a thin, flexible tube with a camera called an endoscope to examine and remove early-stage cancerous tissues. It’s like using a tiny camera to check inside the stomach and do the needed repairs.

2. Subtotal Gastrectomy: 

In this operation, the doctor removes the part of the stomach where the cancer is located, along with nearby lymph nodes. The remaining stomach is then reconnected to the small intestine, allowing digestion to continue as normally as possible. It’s like taking out the affected section of a garden hose and reconnecting the ends.

3. Total Gastrectomy: 

This surgery involves removing the entire stomach to get rid of the cancer. After that, the surgeon creates a new connection between the esophagus (the tube that connects our mouth to our stomach) and the small intestine. It’s like removing the entire garden hose and replacing it with a new one.

After surgery, it may take time for the body to adjust to the changes. Eating smaller, more frequent meals and following a specific diet may be necessary for proper digestion. However, doctors and dietitians can help patients adjust to these changes and maintain good nutrition.


It’s important to remember that surgery may not be suitable for all stomach cancer patients, as it depends on the stage of the cancer and the overall health of the individual. That’s why doctors thoroughly assess each case and discuss the best possible treatment options with their patients.

Whenever you or someone you know experience the symptoms of stomach cancer it is always beneficial to consult a healthcare provider. The professionals help to judge the situation and diagnose the disease based on the individual’s specific condition.

Frequently Asked Questions (FAQs)

What are the stages of stomach cancer?

Stages  Definition  Symptoms  Treatment options Survival rates 
0 The cancer cells are found only in the innermost lining of the stomach. No specific symptoms in this stage Surgical removal of the affected area or endoscopic treatment to remove the affected tissue Survival rates are high around 90%
I Cancer cells begin to grow into deeper layers of the stomach wall but have not spread to lymph nodes yet. Abdominal pain, bloating, loss of appetite, unexplained weight loss Surgery to remove the tumor, chemotherapy, and radiation therapy The 5-year survival rate is around 60-90% (Depending on the tumor invasion)
II Tumors spread  into more layers of the stomach and might have reached nearby lymph node Persistent indigestion, nausea, stomach pain, and difficulty swallowing Chemotherapy and radiation therapy  The 5-year survival rate varies between 40-70% (depending on tumor size and involvement of lymph nodes)
III Cancer has spread to nearby tissues and lymph nodes but hasn’t affected the other organs Severe abdominal pain, vomiting blood, black stools, and fatigue Combination of surgeries, chemotherapy, and radiation therapy 5-year survival rate reduces to 20-40%
iV Most advanced stage, where cancer has spread to distant organs or tissues Severe pain, significant weight loss, jaundice, and fluid accumulation in the abdomen Chemotherapy, radiation therapy, and biological therapy (just to slow down the further spread) The 5-year survival rate is approximately 4-5%

How is anemia and stomach cancer related?

Anemia and stomach cancer can be related, but it’s important to understand that not everyone with one condition will have the other. Anemia is a condition where a person has a low number of healthy red blood cells. Stomach cancer, on the other hand, is a type of cancer that affects the stomach.

The reason these conditions can be related is that stomach cancer can cause bleeding in the stomach. This bleeding can lead to a decrease in the number of red blood cells (RBC), causing anemia. When a person has anemia, they may experience symptoms such as feeling tired, weak, or dizzy because their body doesn’t have enough healthy red blood cells to provide oxygen to their organs.

If someone has both stomach cancer and anemia, their doctor needs to find out the cause of the anemia. They may need to do more tests to understand if the anemia is due to bleeding from stomach cancer or another reason.

It’s always best to consult with a healthcare professional if you have concerns about your health or if you or someone you know may be experiencing symptoms like anemia. They can provide the necessary guidance and care.
