Paraneoplastic Neurologic Syndromes (PNS) are a group of rare disorders that occur in some individuals with cancer. These syndromes are not contagious and cannot be transmitted from person to person. PNS are caused by an abnormal immune response triggered by the presence of cancer in the body.
When a person develops cancer, their immune system may mistakenly attack healthy cells in the nervous system, leading to the development of PNS. The immune response is not directed against the cancer cells themselves, but rather against proteins expressed by both the cancer cells and the nervous system cells. This immune response can cause various neurological symptoms.
It is important to note that PNS are not caused by a virus, bacteria, or any other infectious agent. They are a result of the body's immune system reacting to the presence of cancer. Therefore, there is no risk of transmitting PNS to others through contact or close proximity.
Although PNS are not contagious, it is crucial to seek medical attention if any neurological symptoms develop in individuals with cancer. Early diagnosis and treatment of PNS can help manage symptoms and improve the overall prognosis.
