For patients with liver cancer, if there is pain in the right shoulder, it is not necessarily continuous, which depends on the specific cause of the right shoulder pain. If the pain is caused by bone metastasis of liver cancer to the right shoulder, the pain is often severe and persistent. Bone is one of the more common sites of metastasis for liver cancer. For bone metastases of liver cancer, we can use imaging studies to detect clear bone destruction at the metastatic sites on X-rays, CT scans, and MRI. If the right shoulder pain in liver cancer patients is caused by other benign conditions, the pain may not necessarily be persistent. For instance, liver cancer patients may also experience shoulder pain due to other conditions such as rotator cuff injuries, periarthritis, or minor trauma, but this pain is not necessarily continuous.
