Nephritis can arise in cancer patients due to several reasons. Firstly, certain cancers, such as renal cell carcinoma and multiple myeloma, directly affect the kidneys. Secondly, cancer treatments like chemotherapy, immunotherapy, and radiation therapy can have nephrotoxic effects, leading to inflammation and damage to the kidneys. Moreover, cancer-related conditions such as paraneoplastic syndromes can also contribute to the development of nephritis.
