Many people think of cancer when they hear the word “tumor.” But not all tumors are cancerous.
If you have been diagnosed with a tumor or you suspect you may have one, it’s important to know about the different types of tumors and the risks they pose.
What Is a Tumor?
A tumor is a cluster of abnormal cells that develop into a lump or growth. Depending on the type of cells it contains, a tumor can be benign, precancerous/premalignant, or malignant.
- A benign tumor does not contain cancerous cells.
- A precancerous or premalignant tumor contains abnormal cells that could become cancerous.
- A malignant tumor contains cancerous cells.
What Causes Tumors?
It’s usually not possible to pinpoint the exact cause of a tumor, but certain risk factors may increase a person’s chances of developing one. These include (but are not limited to):
- Genetics
- Age
- Exposure to toxins, radiation, or chemicals
- Chronic inflammation or infection
- Local trauma or injury
- Diet
- Stress
It’s important to see a doctor or oncology specialist right away if you see or feel an abnormal lump or growth anywhere on your body. If you are diagnosed with a tumor, your healthcare provider will determine whether it is benign or malignant and develop a treatment plan for you.
