Be alert to skin cancer if skin itching occurs

Many people don’t know that itchy skin may be a sign of something wrong with the body or a manifestation of skin cancer . Its characteristic is that no changes can be seen on the surface of the skin, only unbearable itching, and any antipruritic drugs are ineffective. Let’s take a look at the details below.

Data show that 16%-30% of elderly people with malignant lymphoma, 25% of patients with reproductive organ malignant tumors, 25%-60% of elderly women with cancer, and 50% of patients with rectal malignant tumors will experience varying degrees of skin itching. Experts say that itching is closely related to visceral malignant tumors. The cause is currently unknown, but experts speculate that it may be that tumor tissue cells produce histamine and some bioactive substances. After these substances reach the skin through blood circulation, they stimulate the sensory nerve endings of the skin, causing varying degrees of skin itching, which is especially obvious in the early stages of the disease.

Localized itching may sometimes indicate the presence of tumors in nearby areas. For example, itching in the vulva is common in cervical cancer, itching around the anus indicates intestinal cancer, and itching in the nostril wall may indicate a brain tumor. However, the severity and duration of itching have nothing to do with tumors. Therefore, persistent itching of the skin with unknown cause should not be treated with scratching. It should be identified as soon as possible and treated promptly, because it may be a manifestation of skin cancer.
