Chances are, you’ve heard the terms ”benign” and ”malignant” in reference to tumors, but what do these words mean? Read this lesson to learn more about benign tumors.
Definition of Benign Tumor
A benign tumor is a non-cancerous tumor (as opposed to a malignant tumor, which is cancerous) that forms somewhere in or on the body.
A benign tumor does not spread to surrounding tissues or other parts of the body, and it might or might not cause harm, based on its location and size.Each case of a benign tumor is individually reviewed to determine if treatment is necessary. Unlike malignant tumors, some benign tumors can be left alone and never cause any harm.
Causes of Benign Tumors
What causes a tumor to develop when it isn’t cancerous? As with many tumors, scientists are not completely sure. However, there are risk factors that increase the likelihood of a tumor developing.
These include radiation exposure (which can be environmental, industrial, or even in the form of radiation therapy treatment for cancer), family history of tumors and/or cancers, diet, stress, injury, and even infection.
Types and Examples of Benign Tumors
There are many types of benign tumors, so let’s jump in and start learning about some of them!
- Adenomas: These tumors form in the tissues that cover glands or gland-like structures in the body. They aren’t common and can develop into malignant tumors. One common example is a polyp that has formed in the colon.
- Fibromas: These tumors develop on connective tissues found anywhere in the body. They’re most commonly found in the uterus.
- Hemangiomas: These tumors are a type of birthmark and are caused by a buildup of blood vessels in a certain part of the body (usually the skin but sometimes another organ). They’re most commonly found on the head, neck, or trunk of the body.
- Lipomas: These are slow-growing tumors that form from fat cells.
They commonly run within families, but they also can form as a result of an injury.
- Papillomas: These tumors grow from epithelial tissues (those that cover organs or glands) and often develop in women as a result of contracting HPV (human papillomavirus).
Benign tumors are non-cancerous collections of cells. They don’t spread to the rest of the body unless they become malignant (cancerous). Scientists are still researching causes of these tumors, but it’s believed that radiation exposure, family history, diet, stress, infection, and injury might be risk factors that increase the likelihood of a benign tumor developing.There are several types of benign tumors, which can form almost anywhere in or on the body. Each occurence of a benign tumor should be monitored by a doctor to decide if further treatment is necessary
