Air travel and smoking cigarettes are two vastly different activities that expose individuals to different types of risks. While both can have health implications, they involve distinct mechanisms and levels of exposure. Let’s delve into the specifics of each to…
A PET scan, or Positron Emission Tomography scan, is a medical imaging technique that uses a small amount of radioactive material to help doctors see how tissues and organs are functioning inside the body. Because it involves radiation, many people…
## The Myth: Is a Chest X-ray Equal to Smoking 10 Cigarettes? You might have heard the claim that getting a chest X-ray is as harmful as smoking 10 cigarettes. This idea pops up in conversations about medical imaging and…
## Understanding Radiation from Chest CT Scans and Cigarettes Let’s start by breaking down what a chest CT scan is and why people sometimes compare its radiation to something as everyday as smoking cigarettes. A chest CT (computed tomography) scan…
Smoking one pack of cigarettes a day for a year exposes the body to harmful chemicals and radiation, but quantifying this exposure in terms of an equivalent radiation dose measured in millisieverts (mSv) is complex and not straightforward. However, rough…
Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive cancer that arises in the nasal cavity and paranasal sinuses. Because of its aggressive nature and complex location near critical structures like the eyes and brain, treating SNUC requires a carefully coordinated,…
Esthesioneuroblastoma, also known as olfactory neuroblastoma, is a rare type of cancer that originates from specialized nerve cells responsible for the sense of smell, located in the upper part of the nasal cavity. The exact cause of esthesioneuroblastoma is not…
Olfactory neuroblastoma is a rare type of cancer that originates in the upper part of the nasal cavity, specifically affecting the olfactory system responsible for the sense of smell. This condition is often overlooked initially because its symptoms can mimic…
Atypical teratoid rhabdoid tumor (ATRT) is a rare and aggressive type of cancer that primarily affects the central nervous system, especially in very young children. The cause of ATRT is fundamentally linked to genetic mutations, particularly involving genes that regulate…
Central neurocytoma is a rare type of brain tumor that originates from the cells of the central nervous system. These tumors are typically benign and are most commonly found in young adults. Despite their benign nature, central neurocytomas can cause…
