As of 2015, the best way to prevent metastatic cancer is by finding tumors early, removing and destroying them, according to the American Cancer Society. Early detection tests for colon cancer, breast cancer and cervical cancer make it more likely to find cancer before it spreads.Continue Reading
After the removal of the tumor, the American Cancer Society indicates doctors often provide other treatments to prevent spreading of cancer cells. Depending on the location of the tumor, options include radiation therapy and chemotherapy. These therapies along with emerging treatments help to locate and treat cells that break away from the initial tumor.
Even if an individual has the recommended tests, cancer may have metastasized before its discovery, indicates the American Cancer Society. There are no accurate early tests for some cancers, and others spread rapidly. However, having the screening tests reduces the chances of a tumor spreading to other tissues.
Metastatic tumors spread from one area of the body to another. A primary tumor located in the lung may transmit cancer cells through the blood to the brain. These cells continue to grow and divide forming a brain tumor. Lung tumors tend to metastasize more quickly than other types of tumors, according to Drugs.com. These secondary tumors continue growing until they are treated.Learn more about Cancer
