Unlike a Mass effect (medicine), mass effect, it is not due to the local presence of cancer cells. Paraneoplastic syndromes are typical among middle-aged to older patients, and they most commonly present with cancers of the Lung cancer, lung, Breast cancer, breast, Ovarian cancer, ovaries or lymphatic system (a lymphoma). Sometimes, the symptoms of paraneoplastic syndromes show before the diagnosis of a Malignant, malignancy, which has been hypothesized to relate to the disease pathogenesis.
