Characteristics of malignant tumor skin itching

The characteristics of malignant tumor skin itching mainly include no obvious inducement and continuous non-remission, extensive and stubborn itching, may be accompanied by other symptoms, night itching may be more obvious, can be repeated attacks, etc. 1. No obvious inducement and continuous non-remission This itching often can not find a clear external cause, such as mosquito bites, dry skin, etc., and lasts for a long time difficult to subside. This is because tumor cells may produce some bioactive substances, such as histamine, which cause skin paresthesia and itching. 2. Pruritus is widespread and stubborn. It may involve multiple parts of the body, not limited to one part, and conventional antipruritic treatment is ineffective. This is due to the extensive action of tumor-related abnormal substances in the body. 3. May be accompanied by other symptoms In addition to itching, patients may also be accompanied by jaundice, emaciation, fatigue and other tumor-related manifestations. The combination of these symptoms suggests that it is necessary to be highly alert to the possibility of malignant tumors. 4. Night itching may be more obvious. In the quiet state at night, patients may feel more sensitive to itching, resulting in increased itching at night and affecting sleep quality. 5. Recurrent attacks Even if the itching is temporarily relieved after certain treatment, it may reappear, showing the characteristics of recurrent attacks. This has a certain relationship with the persistence and progression of the tumor. In conclusion, when there is no obvious cause, persistent, extensive and stubborn skin itching, accompanied by other abnormal manifestations, the possibility of malignant tumor should be highly suspected, and timely medical examination and diagnosis should be carried out in order to detect and treat potential malignant tumor at an early stage.
