At first, Sarah chalked it up to allergies. A slight itch on her arms became a persistent irritation that spread across her entire body. It was spring, after all—pollen, dust, maybe even a new detergent. But when antihistamines didn’t work and the itching got worse—keeping her up at night, disrupting her work—she started to worry.

She visited her primary care doctor, who suggested it was probably eczema or a seasonal allergy flare-up. But something didn’t sit right. There were no rashes, no hives, no obvious skin reactions—just an intense, unrelenting itch from the inside out.

A dermatologist ruled out common skin conditions and, noting that her liver enzymes were slightly elevated in a routine blood test, referred her to a specialist. That’s when the truth started to unfold.

Further testing revealed the real culprit: a rare form of Hodgkin lymphoma.

In some cases, intense, unexplained itching (also called pruritus) can be an early warning sign of certain cancers—particularly lymphomas. It’s often caused by the immune system reacting to cancer cells or the release of specific proteins in the blood. While not the most common symptom, it’s a recognized one—especially when no external cause is found.

Sarah began treatment soon after the diagnosis. Early detection made a huge difference in her prognosis. While chemotherapy and radiation were tough, she’s now in remission and recovering well.
