Itching on the body is not related to cancer in any way. If a tumor has occurred and is diagnosed, whether itching on the body is caused by complications of the tumor, by some other related bad secretion’s causing itching on the body, or by high jaundice causing itching on the body, is even possible. If there is no diagnosis of tumor, the itchy skin is not related to tumor, so it is not necessary to consider tumor. Itchy skin has nothing to do with the occurrence of tumor. There is hardly any tumor that has itchy skin as a main symptom from early to late stage. If itchy skin is limited to two conditions: 1) high jaundice, which causes itchy skin after tumor causes high jaundice; 2) some abnormal secretion of tumor causes abnormal secretion of toxin, which occasionally causes itchy skin. A single itchy skin symptom is generally considered not to suggest the occurrence of tumor.
