👉 Odd-infection, also known as atypical or paraneoplastic infections, refers to a condition where an individual develops an immune response against their own tissues, often triggered by the presence of cancer. Unlike typical infections caused by pathogens like bacteria or viruses, which target specific cells or organs, odd-infections occur when the immune system mistakenly identifies normal host cells as foreign due to molecular mimicry or other mechanisms associated with cancer. This can lead to inflammation and damage in various parts of the body, even those not directly involved in the malignancy. For example, a patient with breast cancer might develop an infection in the liver or skin that isn't caused by bacteria or viruses but by the immune system's overactive response to cancer-related antigens. These infections can be challenging to diagnose and treat, as they often require a different approach from conventional treatments targeting pathogens.
