Metastatic Cancers
Metastatic cancers refer to tumors that originate in another part of the body and then spread to the central nervous system (CNS). These types of cancers are more prevalent compared to primary cancers. Lung cancer accounts for approximately 50% of all metastatic brain and spinal cord tumors. Additionally, other cancers that can metastasize to the CNS include melanoma, nasopharyngeal cancer, colon cancer, breast cancer, kidney cancer, and cancers of unknown primary origin.
Diagnostic Tests
Medical professionals employ various diagnostic tests and imaging procedures to confirm the presence of cancer. The diagnostic process usually commences with a thorough physical examination and review of the patient’s medical history to identify any abnormal lumps or underlying health issues. Additionally, a neurological examination may be conducted to assess any loss of function in the brain, spinal cord, or nerves. In many cases, medical imaging techniques like CT scans, MRI scans, or PET scans are instrumental in detecting tumors or abnormal cell growth. If an imaging test reveals the presence of a tumor, surgeons often perform a biopsy to definitively establish the tumor’s existence and determine its severity.
