Can cancer cause itchy skin?

Itching (pruritus) can indeed occur in some cancer patients. While pruritus is a common dermatological symptom, persistent, widespread, unexplained itching may signal an underlying malignancy—particularly one located near the affected skin area.

In addition to pruritus, certain cancers may manifest with blistering skin lesions. For instance, patients with cancer—especially those with lymphoid malignancies—may develop herpes zoster–like skin eruptions; the incidence increases with age. Similar zosteriform lesions have also been reported in esophageal, gastric, colorectal, lung, and prostate cancers. Moreover, erythematous patches, papulovesicles, small vesicles, or grouped urticarial plaques may appear on the posterior axillary region, sacrum, buttocks, or lateral forearms. In severe cases, patients may develop dermatitis herpetiformis–like eruptions.
