Chest pain in cancer patients can arise from various factors. It can be directly related to the cancer itself, such as when a tumor in the chest or lung area exerts pressure on surrounding tissues and nerves. Additionally, cancer metastasis to the bones, lungs, or pleura can also cause significant discomfort. Other times, chest pain may be a side effect of cancer treatments, including chemotherapy, radiation therapy, or surgery. For some patients, pre-existing conditions unrelated to cancer, such as cardiovascular disease, can also contribute to chest pain.
