As temperatures drop in Texas, many people experience dry and itchy skin. While this is often a harmless result of cooler, drier weather, experts warn that persistent itchiness can sometimes indicate a more serious health issue.
Dr. Jennifer Maender, a dermatologist at Houston Methodist, explains that while most cases are minor, ongoing itching should not be ignored. “In many cases, it’s something minor,” says Dr. Maender. “But if it is skin cancer, catching it early makes a big difference.”
Research indicates that about 45% of squamous cell carcinomas cause uncomfortable itching. Other types of skin cancer such as basal cell carcinoma and melanoma may also lead to similar sensations. Dr. Maender points out that changes in how the skin feels—such as itching, pain or tingling—can be important clues alongside visible changes.
“While many people first notice skin cancer because of how it looks, sensation changes such as itching, pain or tingling can also be important clues,” Dr. Maender says.
She advises seeing a doctor if an itch lasts four to six weeks without improvement or if the itchy area appears unusual—such as changing shape or color or failing to heal. Itchy patches linked with redness, scaliness or inflammation may also warrant medical attention.
“If a basal cell carcinoma, squamous cell carcinoma or melanoma is itchy, you’ll often notice redness or irritation around the lesion,” says Dr. Maender. “That’s because the immune system is reacting to abnormal cells in the area.”
Persistent itching accompanied by other symptoms like fatigue, unexplained weight loss or fever should prompt further evaluation by a healthcare provider. Some internal cancers—including lymphoma and cancers affecting the liver, bile duct and pancreas—can present with widespread itchiness even without visible rashes.
Lymphoma frequently causes all-over itching; liver and bile duct cancers can raise bilirubin levels leading to itchiness and jaundice; pancreatic cancer blocking the bile duct can produce similar effects; inflammatory breast cancer may cause rash or itchiness on the breast.
“Kidney disease can also be a culprit,” Dr. Maender says. “While these cases are less common, they’re another reason persistent itching should never be ignored.”
Most cases of itchy skin during colder months are unrelated to cancer and instead stem from seasonal dryness, allergies, eczema or psoriasis.
“Many people develop drier, itchier skin as the weather cools,” Dr. Maender says. “Sometimes getting relief is as simple as switching to a fragrance-free moisturizer formulated for sensitive skin.”
Over-the-counter products can help relieve mild symptoms without increasing risk for more serious conditions: scratching does not make skin cancer spread faster but can break fragile skin and increase infection risk.
“The main risk is that scratching can break the skin and lead to infection,” says Dr. Maender. “That’s because the skin is often more fragile, making it easier to injure.”
Non-steroidal anti-itch ingredients like pramoxine and natural remedies such as colloidal oatmeal are recommended for daily use in managing dry or eczema-prone skin.
“These are excellent over-the-counter choices, especially for older adults who often develop drier, itchier skin,” notes Dr. Maender.
If symptoms persist despite home treatment—or if there are additional concerning signs—a medical evaluation is advised.
“Don’t ignore what your skin is telling you,” Dr. Maender says. “When something looks or feels off, it’s best to get it checked.”
