While hives (chronic urticaria) can be a rare sign of various cancers, they are most commonly linked to blood cancers like lymphoma, leukemia, and multiple myeloma, but can also precede or accompany solid tumors such as breast, lung, liver, pancreatic, and neuroendocrine tumors, often due to immune responses or chemical releases, and warranting medical investigation for an underlying malignancy.
It's definitely rare, but a few cases of cancer have been linked to chronic hives. And at least one large population-based study suggests people with chronic hives may be at increased risk for developing certain kinds of cancer, like cancer of the blood or lymph nodes.
When a rash caused by skin lymphoma (also referred to as cutaneous lymphoma) is in its early stages, it often presents as small patches of dry, red skin on the torso, buttocks or another area of the body. At this stage, the rash often resembles dermatitis, eczema or psoriasis.
The most common autoimmune conditions seen with hives include thyroid disease, rheumatoid arthritis, and Type 1 diabetes. You can also experience hives if you have lupus, vasculitis, and liver diseases. If you have an autoimmune condition, you usually have other symptoms in addition to hives.
Cutaneous T-cell lymphoma, also called CTCL, can cause rash and slightly raised or scaly round patches on the skin. Sometimes other growths appear on the skin. There are several types of cutaneous T-cell lymphoma.
A Quick Review
A leukemia rash may develop due to the cancer cells that spread to the skin or in response to treatments. It's rare, and most rashes do not result from leukemia. Consult a healthcare provider if you have an unexplained rash.
Signs of Cancer
Eczema. Eczema can look like hives. Both have red patches of itchy skin. Eczema, however, also has small, raised bumps.
How patients described their first signs of lymphoma
a painless lump or swelling, usually in your neck, armpit or groin – this is the most common symptom. pain in the glands in your neck, armpit or groin when you drink alcohol. a high temperature. night sweats.
Chronic urticaria as a paraneoplastic syndrome preceding a cancer diagnosis has been reported for various malignancies, including breast,5, 6, 7 non-small cell lung,11 neuroendocrine,12 colorectal,13,14 prostate,15 and chronic lymphocytic leukemia.
Some general signs and symptoms associated with, but not specific to, cancer, include:
Hives that last longer than six weeks or with recurring outbreaks over a six-week period are most commonly caused by viral or bacterial infections like Helicobacter pylori (bacteria in the stomach), hepatitis or a dental infection. Autoimmune diseases like lupus and Hashimoto disease can also cause hives.
Hives are raised, itchy patches on your skin that are often caused by an allergic reaction, but not always. Surprising triggers include heat, pressure, sweat, mood, and infections, among other health conditions.
Hives are raised, itchy welts that often result from an allergic reaction and can appear suddenly, moving around the body. In contrast, rashes are usually flat, can vary in appearance, and may result from factors like viral infections, skin irritation, or eczema.
Early detection can dramatically improve cancer outcomes, but some cancers remain stubbornly difficult to diagnose at early stages. Pancreatic, ovarian, lung, liver, and kidney cancers present unique challenges that often delay diagnosis until the disease has advanced.
Only 5–10% of all cancer cases can be attributed to genetic defects, whereas the remaining 90–95% have their roots in the environment and lifestyle.
