I’ve been stating this connection for years. Of course cancer is Pathogenic, of course long term or chronic disease is pathogenic, of course autoimmune is pathogenic. It’s all pathogenic if you look deep enough or are honest with yourself about the condition.
A new New England Journal of Medicine case report describes an extraordinary and previously undocumented phenomenon in which malignant cells found in a human patient originated from a parasitic tapeworm rather than from the host’s own tissues. The patient, a severely immunocompromised man with HIV infection, presented with invasive tumors in the lungs and lymph nodes composed of small, undifferentiated cells. Although the lesions exhibited classic features of cancer, their unusual morphology prompted further investigation, which revealed that the cells were nonhuman in origin.
Using molecular and genomic analyses, the investigators identified DNA from Hymenolepis nana, a dwarf tapeworm, within the tumor cells and demonstrated genetic alterations consistent with malignant transformation. These findings indicate that tapeworm cells had undergone neoplastic change and subsequently invaded human tissues, representing a novel disease mechanism that bridges infection and cancer. This case challenges traditional concepts of oncogenesis and underscores the complex interactions between pathogens, host immunity, and malignant disease.
