Difference Between Benign and Malignant Tumors (With Table)

A Tumor is a mass of abnormal cells in the body. It is caused when cells divide more than they are supposed to and do not get destroyed later. This causes a cluster of cells to be formed in our body. Tumors can be classified into two categories: Benign Tumor and Malignant Tumor.

Benign vs Malignant Tumors

The difference between Benign and Malignant Tumors is that Benign Tumors are often not as concerning, but on the other side, Malignant Tumors can be threatening. Benign Tumors, unlike Malignant Tumors, stay where they were originated and do not spread as much. The majority of Benign Tumors develop slowly. The growth rate of Malignant Tumors is generally rather fast.

Benign Tumors place and do not spread to other parts of the body and stay where they were originated. They do not expand to other areas of the body or local structures. Benign Tumors have defined boundaries and develop slowly. Normally, Benign Tumors aren’t an issue. They can, however, become big and crush adjacent structures, producing discomfort or other medical issues.

Malignant Tumors have uncontrolled cell growth that spreads locally or to distant locations. Malignant Tumors are cancerous (ie, they invade other sites). They spread through the circulation or lymphatic system to distant locations. Metastasis is the medical term for this type of spread.

Comparison Table between Benign and Malignant Tumors

Parameters of comparisonBenign TumorMalignant Tumor
EffectBenign Tumor is less harmful than Malignant tumor.Malignant Tumor is made up of cancerous cells hence it can be more of a threat to the body.
Growth rateBenign Tumors have a slow growth rate. Malignant Tumors have a faster growth rate and spread quickly.
Capability to spreadBenign Tumors do not spread and remain where they originate.Malignant Tumors can travel through lymph nodes and can spread to different parts of the body.
Threat If the Benign Tumor is not much threat to our health, it can be sometimes ignored.It is not wise to disregard Malignant Tumors. Malignant Tumors can secrete substances causing tiredness, and loss in weight.
Possibility of recursionBenign Tumors rarely return, and if they do, they remain on their site of origin.Malignant Tumors can return and spread around, causing them to be life-threatening.

What is Benign Tumor?                                           

The Benign Tumor cells are not cancerous. It won’t spread to other parts of the body or infect neighboring tissues. Unless it is pushing on adjacent tissues, nerves, or blood arteries and causing harm, a benign tumor is less concerning. Benign Tumors include fibroids in the uterus and lipomas.  

Removal of Benign Tumor can be done by contacting a specialized surgeon. They may grow to be quite big, weighing up to pounds. When they form in the brain and crowd the usual structures in the enclosed area of the skull, they can be hazardous. They can push on critical organs and obstruct pathways.

Certain benign tumors can develop into malignant cancers. These are constantly monitored and may need to be surgically removed. Colon polyps can become cancerous, therefore they’re generally removed surgically. Some benign tumors, such as intestinal polyps, are regarded as precancerous and must be removed to avoid turning cancerous.

 Benign tumors seldom return after being removed, but when they do, it’s generally in the same location. The growth rate of Benign tumors is slow, and hence they do not spread in the other parts of the body. Sometimes, Benign tumors can be disregarded too, if they are not that concerning.

What is Malignant Tumor?                            

Malignant’ refers to a group of cells that are cancerous, and are capable of spreading in our body. A Malignant Tumor can spread very quickly, through lymph nodes. This process of spreading harmful cancerous cells in the body is called Metastasis.

Cancer may strike many parts of the body. Luckily, there is also no apparent sign of tumor growth in over 90% of individuals who have a malignant tumor identified. Nevertheless, this does change the possibility of limited regions of dissemination existing.

Our bodies are continuously producing new cells to replace the ones that have died. In certain cases, DNA is damaged throughout the process, resulting in aberrant cell development. Instead of dying, they keep multiplying faster than the immune system can manage, eventually creating a tumor.

Cancer cells can break out from tumors and migrate to other regions of the body via the circulation or lymphatic system. The cancerous cells which spread to many other regions of the body are identical to the originals, and they can infiltrate different organs.

Main Differences between Benign and Malignant Tumors

  1. Benign Tumors do not have cancerous cells like Malignant which makes them less harmful than Malignant Tumors.
  2. Benign Tumor cells have slower growth than Malignant Tumors.
  3. A Benign Tumor does not spread from its original location, Malignant Tumors, however, can travel through lymph nodes and can spread to different parts of the body.
  4. If the Benign Tumor is not much threat to our health, it can be ignored. However, Malignant Tumors can secrete substances causing tiredness, and loss in weight.
  5. Benign Tumors seldom return after being removed, Malignant Tumors can return causing them to be life-threatening.


Both Benign and Malignant Tumors are the type of tumors, which is an abnormal mass found in our body. Benign Tumors are curable and are not that much of a threat, it is not the same case in Malignant though. Malignant tumors can spread through bloodstreams and can come as a warning to our health.

Benign Tumors can be ignored sometimes if they are safe, however, sometimes the big masses of them can suffocate or compress the trachea causing pain and breathing problems. In that case, it is advised to get them removed. When a Malignant Tumor is discovered in the body, its treatment includes chemotherapy with systematic surgery.
