Before cancer appears, the body may show early warning signs—especially in the hands and feet. These subtle symptoms are often overlooked but could indicate deeper health issues.

First, persistent numbness or tingling in the hands or feet may signal nerve damage caused by conditions like **multiple myeloma or certain types of leukemia**. As the article notes, “This numbness can result from tumors pressing on nerves or the cancer affecting nerve function.”

Second, **swelling without injury**, especially in the hands or feet, may suggest lymphoma or kidney-related cancers. This occurs when “lymph nodes or organs are compromised, leading to fluid buildup.”

Third, **skin changes** like dark spots, unusual bruising, or sores that don’t heal can indicate skin cancer or blood cancers. The article explains, “Some cancers reduce blood platelet counts, causing unexplained bruising.”

Finally, constant **pain or discomfort in extremities**, not caused by physical strain, might point to bone or blood cancers. “When cancer spreads to the bones, it can cause persistent aches—particularly in the hands or feet,” the article states.

While these signs don’t always mean cancer, noticing and addressing them early can lead to faster diagnosis and better outcomes.
