Heel pain in one foot is not an early sign of cancer. Cancer can cause heel pain as a symptom, but heel pain is mostly caused by other reasons such as trauma. Heel pain can be caused by tumors such as primary malignant bone tumors, which tend to grow in the epiphysis where the blood supply is rich. The heel bone has a richer blood supply, so it can grow in the heel area. The second kind of metastatic malignant bone tumor, such as lung cancer and other cancers, can metastasize to the lumbar vertebrae and vertebral arch root, resulting in spinal cord nerve compression leading to radiating pain in the heel, so it is possible to cause a heel pain. Heel pain can be caused by inflammation such as plantar fasciitis and subtalar bursitis, or by osteophytes and spurs on the heel bone, or it can be caused by trauma. To determine the exact cause of heel pain, it is necessary to go to the hospital for diagnosis to avoid excessive anxiety and to identify and treat the cause.
