Radiation necrosis, a focal structural lesion that usually occurs at the original tumor site, is a potential long-term central nervous system (CNS) complication of radiotherapy or radiosurgery. Edema and the presence of tumor render the CNS parenchyma in the tumor bed more susceptible to radiation necrosis. Radiation necrosis can occur when radiotherapy is used to treat primary CNS tumors, metastatic disease, or head and neck malignancies. It can occur secondary to any form of radiotherapy modality or regimen.

Answer: Maintenance therapy
Explanation:
This is a type of maintenance therapy that is used usually at the beginning of the treatment. Methadone is also opioid which means that is addictive but it is not the same as heroin.
Methadone is also bad, but it is safer for patients, it is taken orally, it is not injected as heroin so it cannot lead patients to various diseases such as HIV. Another different and good thing is that there is no need for the crime of stealing when it comes to methadone.
- This type of therapy is used as a beginning of the treatment because there is no other way when a person is heavily addicted. After this, there is detoxication, which is a hard treatment for heroin addicts but it can lead to healing.
