Patients ask us why they have a tumor. Was it DNA? Something they did wrong? The answer may not be as simple as you think. Here, Dr. Joseffer provided a layman's explanation of why this has happened.
We do not usually have an explanation for why someone gets a brain tumor. While some types of tumor are clearly linked to environmental exposures, such as with lung cancer and smoking, there is no similar explanation for most brain tumors. People are often worried about cell phone use, but there is no conclusive evidence to support that belief. Tumors arise when cells lose the regulatory mechanisms that control their growth. This loss of regulation comes from changes in the DNA of the cells. These changes are often created randomly and we do not usually have an explanation for why it happened to an individual person.
