Tumors And Their Different Types

May 4, 2017

Everyone is familiar with the word cancer but not everyone really knows if it is the same as a tumor. A tumor is just a mass of tissue and may not necessarily be cancerous. They are classified into two major types.

  • Benign tumor
  • Malignant tumor

Below we explain the two types in detail.

  1. Benign tumor

In this case, the cells divide rapidly but are found only in one part of the body and do not spread to other parts of the body. They are relatively harmless and can be treated. But because the cells continue to multiply, they can become very large and cause problems to adjacent cells, tissue and organs. Due to this reason, they have to be treated in many cases. Below you can find some types of benign tumor

  • Adenoma

These are formed in the membrane covering the various glands, organs and other parts of the body. Though an adenoma is not cancerous, they have the potential to become one.

  • Fibroids

These are formed in the fibrous and connective tissues like the uterus and skin.

  • Hemangioma

Strawberry marks or red birthmarks are hemangiomas caused by accumulated blood cells. These usually go away with age.

  • Lipoma

These are caused due to the accumulation of fat cells and are usually harmless and painless. They can be found as small lumps on the skin.


  1. Malignant tumor

This is what is known as cancer and are progressive tumors that spread, resist treatment and have the potential to be fatal. Below are the different types of malignant tumor.

  • Carcinoma

In a carcinoma, the tissues that line the various organs are affected. The risk of this type of tumor increases with age.

  • Sarcoma

The tumor caused in the connective tissues, fat, nerves and bones is called a sarcoma.

  • Lymphoma

The blood-forming cells in the bone marrow cause this type of cancer and eventually causes cancer of the blood called as Leukemia.
