Ionizing radiation, which often becomes a salvation for patients with oncology, is often associated with the development of complications. Radiation necrosis becomes a serious consequence of therapy. Also, people are exposed to him, whose professional activities are associated with frequent radiation exposure and high-voltage irradiation.
Features of development of radiation necrosis?
Necrosis appears in the form of foci in soft and bony tissues, and the timing of its development depends on many factors:
- general state of the organism;
- the amount of malicious training received;
- dose values.
Neurotoxic substances in antitumor drugs also cause disorders and radiation necrosis.
When the spinal cord is affected
Symptoms of spinal cord necrosis are manifested as fever, back pain and migraine. It is interesting that the disease can appear even due to trauma or microcrack. The most difficult disease is therapy, when it is located in the upper cervical spine. Necrosis quickly spreads both up and down the vertebral column.
Pathology is difficult enough to treat, and entails persistent severe disorders of body functions, often irreversible.
Defeat of the brain
In contrast to the pathology of the spinal cord, radiation necrosis of the brain has no symptoms. That is, all four stages, from paranecrosis to complete cell death, are asymptomatic. There may be insignificant headaches , but they are no different from the usual malaise.
Necrosis after radiation therapy appears when treating a tumor in the head. After exposure to the formation itself, the fluid accumulates in the brain's material, there is an edema that prevents the flow of blood, and, consequently, oxygen. This leads to partial or complete death of cells and tissues.
