Imagine that you went for a scan for some other stomach problem. The doctor who looked at your report suddenly says, "There's something that looks like a small tumor in your liver." At that moment, your body goes numb, doesn't it? When we hear the word 'liver tumor', the fear of 'cancer' comes to most of our minds. But are all tumors that develop in the liver really cancer? Or is this not something to be afraid of? Today, we will talk about this in detail to resolve all the questions that are on your mind.
Simply put, what are these liver lesions?
A liver tumor, or as doctors call it, a ``Liver Lesion,'' is an abnormal growth of cells inside your liver. It's like a birthmark or a small lump on our skin. These are also called ``mass'' or ``tumor''.
The important thing is, not all of these nuts are the same. There are mainly two types:
1. Benign tumors: These are the most common. They are not cancerous. This means they do not spread to other parts of the body. Most of the time, they do not cause any harm. Most people live with these tumors throughout their lives without any problems.
2. Malignant tumors: These are the type we should be afraid of. These are called liver cancer. They can grow out of control and spread to other parts of the body. This is a serious condition that definitely requires medical attention.
Often, a person discovers that they have a tumor like this by chance during a scan done for another reason. So there's no need to panic right away. The important thing is to first find out exactly what type it is.
Benign tumors that are nothing to be afraid of
As we said, these are non-cancerous, or harmless, tumors that are often seen. There can be various reasons for them to occur. Let's look at the main types.
| Type of Lesion | A simple explanation |
|---|---|
| Focal Nodular Hyperplasia | This is a tumor that forms when liver cells clump together. It is usually thought to be caused by a change in a blood vessel that supplies blood to the liver. This is not harmful. |
| Hemangioma | This is like a bunch of blood vessels that are abnormally tangled together. It can be something that is present at birth. These are also usually harmless. But sometimes they can get a little bigger. |
| Liver Adenomas | These are also non-cancerous tumors. They usually form near the surface of the liver. They are most common in women who use hormonal medications, such as birth control pills. |
| Liver Cysts | These are like water-filled blisters. These fluid-filled sacs that form inside the liver usually don't cause any problems. |
The most important thing is that 99% of the above ``benign`` tumors do not show any symptoms. So don't panic even if you find out that you have one.
Types of malignant tumors to watch out for
Now let's talk about the cancerous tumors that we all fear. These can also occur in two main ways.
1. Primary Liver Cancer: Simply put, this cancer starts in the liver itself. Normal liver cells change abnormally and begin to divide uncontrollably. The two most common types of this type of cancer are ``Hepatocellular carcinoma'' and ``Cholangiocarcinoma'' (cancer of the bile ducts).
2. Metastatic Liver Cancer: This is when cancer that has started elsewhere in the body, such as the colon, lungs, or breasts, spreads to the liver through the bloodstream and forms liver tumors. This is also a serious condition.
What could be the symptoms of this?
Symptoms vary greatly depending on whether the tumor is noncancerous or cancerous.
Characteristics of non-cancerous (benign) tumors
These usually do not cause any symptoms. However, very rarely, if a tumor like the one mentioned above (Hemangioma) grows to a size of 30 centimeters (about a foot), it can press on nearby organs such as the stomach and gallbladder. If that happens,
- Stomach discomfort or pain
- A feeling of fullness
You may feel things like that. But this is a very rare occurrence.
Symptoms of malignant tumors
The symptoms of cancerous tumors are more distinct and obvious. If you have one or more of these, you should see a doctor immediately.
- A lump-like sensation under the right rib cage.
- Pain in the right side of the stomach or under the right shoulder.
- Yellowing of the whites of the eyes and skin (Jaundice).
- Weight loss for no reason.
- The food is tasteless.
- Constant fatigue and weakness.
- Abdominal bloating.
Why do these liver tumors occur?
The exact cause of non-cancerous tumors is not yet known, but experts believe that certain factors may contribute to this.
- Birth control pills or hormone therapy: The hormone estrogen in these can have an effect.
- Liver Fibrosis: Scarring of the liver due to long-term liver disease.
- Smoking: Smoking puts pressure on the liver.
Cancerous tumors occur when the DNA of liver cells becomes damaged and begins to grow abnormally and uncontrollably. There are several main factors that increase this risk.
- Cirrhosis: A condition in which the liver becomes completely shrunken and filled with scars due to factors such as excessive alcohol consumption and fatty liver.
- Chronic Hepatitis B and C Infections: These two viral infections are the leading causes of liver cancer.
How exactly does the doctor find this?
If you suspect you have a liver tumor, your doctor will do several tests to confirm exactly what type it is.
You can't immediately tell 100% whether it's cancer or not by looking at a report. You need to do step-by-step tests.
1. Asking you for details: First, the doctor will ask you carefully about your symptoms, your family history, the medications you take, and whether you drink alcohol.
2. Physical examination: The abdomen is palpated to check for swelling of the liver and a lump.
3. Imaging Tests: These tests help to clearly see the inside of the liver.
- Ultrasound Scan
- CT Scan
- MRI Scan
4. Blood Tests: These tests are done to check liver function and to check for things called ``Tumor Markers'' that are elevated in the blood in some types of cancer.
5. Liver Biopsy: This is the most definitive and final confirmation. Here, a very small piece of tissue is taken from the liver tumor using a thin needle and examined under a microscope to see if it contains cancer cells or normal cells.
What are the treatments?
Treatment options depend on whether you have a noncancerous or cancerous tumor.
- For non-cancerous (benign) tumors:
Most of the time , no treatment is needed. Your doctor may just do a scan from time to time to see if it's getting bigger. But only if the tumor is very large and causing symptoms like abdominal pain, can surgery be done to remove the tumor .
- For malignant tumors:
There are several treatment options for this. The doctor will determine the best treatment based on the size of the tumor, its spread, and the patient's overall health.
- Hepatectomy: Surgical removal of the part of the liver that contains the tumor.
- Ablation Therapy: Destroys cancer cells by sending extreme heat, extreme cold, or chemicals into the tumor.
- Chemotherapy: Giving powerful drugs to destroy cancer cells.
- Liver Transplantation: Complete removal of the diseased liver and transplantation of a healthy liver.
Can the liver heal these tumors on its own?
The liver is one of the most amazing organs in our body. It has the amazing ability to regenerate itself by making new cells. For example, even if half of the liver is surgically removed, the remaining part can grow back to the size of a complete liver.
Also, the liver has the ability to repair damage caused by some liver diseases. Therefore, it is possible that damage caused by some non-cancerous tumors may also heal.
But remember this: The liver can never heal a malignant tumor on its own. It definitely requires proper medical treatment.
Is there a way to prevent these from forming?
There is no surefire way to prevent non-cancerous tumors. However, there are many things we can do to reduce our risk of developing cancerous tumors, which are the most serious problem. Simply put, that means keeping our liver healthy.
- Avoid alcohol and smoking: These are two of the main enemies that put excessive stress and damage on the liver.
- Protect yourself from the hepatitis virus: Get vaccinated against hepatitis B. Avoid unprotected sex and sharing needles.
- Eat a balanced diet: Eat more vegetables, fruits, and lean proteins (fish, chicken). Limit foods high in fat and sugar.
- Maintain a healthy weight: Controlling body weight can prevent damage to the liver caused by fat accumulation (Fatty Liver).
It's normal to feel scared when you find out you have a liver tumor. But the most important thing is not to panic, but to get the right tests and find out exactly what kind of tumor it is. Talk openly with your doctor about all your fears and questions. Getting the right information is the best way to get rid of unnecessary fear.
Take-Home Message
- Not all tumors seen in the liver are cancerous. The majority are harmless, non-cancerous (benign) tumors.
- Most of the time, these tumors are discovered by accident. They don't cause any symptoms.
- If you have stomach pain that lasts more than a few days, especially on the right side, be sure to see a doctor.
- The best way to protect yourself from cancerous tumors is to protect your liver by avoiding alcohol and smoking, and adopting a healthy lifestyle.
- If you have any questions about your test results or treatment, talk to your doctor openly about them. Don't be afraid.
