Itchy skin - a warning sign of cancer

Itchy skin can be an early sign of several cancers related to blood cells, skin, liver, and gallbladder.

Itching is often caused by direct skin irritations such as pollen, dry skin, or changes in weather, or indirectly by consuming certain foods. Other medical conditions such as liver disease, kidney disease, or cancer can also be causes. In these cases, itching is often directly related to dermatitis, the accumulation of bile acids under the skin, or chemicals released by tumors.

Blood cancer

All types of cancer involving blood cells can potentially cause itching, but the most common are Hodgkin's lymphoma, leukemia, and cutaneous T-cell lymphoma.

Cutaneous T-cell lymphoma is a rare type of cancer that starts in T cells, a type of white blood cell that can attack the skin, causing rash-like redness, scaly patches, or pus-filled lesions. Itching may persist for years before the cancer develops.

Skin cancer

Skin cancer is a common type of cancer that causes itching. Typically, it's caused by skin cells growing out of control, with a number of skin changes including itching, pain, warts, ulcers, etc.

Other symptoms may include jaundice, abdominal pain, fluid accumulation in the abdomen (ascites), and abdominal cramps.

Vulvar and anal cancer

Itching in the vulva, vagina, or anal area can have many different causes, but sometimes it can be due to a malignant tumor in these areas.

Breast cancer

In addition to the diseases mentioned above, some treatments can cause itchy skin, such as chemotherapy or the use of medications to kill cancer cells. Some medications can cause allergic reactions or hepatitis, leading to itching. Treatments that stimulate the patient's immune system to fight cancer can cause this condition, especially after treatment, when the skin begins to heal.

Patients should see a specialist if they suspect skin itching is due to cancer, or if the itching lasts longer than two days, if they have dark, tea-colored urine, jaundice, or if they scratch until they bleed. Bright red itchy areas that worsen with medication, blisters, scabs, pus, foul-smelling discharge, or facial swelling are also dangerous warning signs.
