Having cancerous nodules in the colon does not necessarily mean metastasis, but can also be a primary lesion. In the early stage, colon cancer patients may form single or multiple cancerous nodules in the colon, which usually belong to primitive tumor foci and are not caused by metastasis. Some patients may have metastatic cancer in other parts of the body, such as lung cancer, liver cancer, etc. Cancer nodules found in colon during examination may mean metastasis. When cancerous nodules are found in the colon, patients should seek professional doctors for early evaluation to see if there is any metastasis of cancerous nodules. In addition, patients should have early and active treatment. Generally speaking, early surgical resection is recommended for colon cancer, followed by combined radiotherapy and chemotherapy (commonly used chemotherapeutic drugs include oxaliplatin, fluorouracil, etc., and the drugs should be taken in accordance with the doctor’s prescription.
