Metastasis is the process by which cancer cells spread from their original site to other parts of the body. It typically occurs in the later stages of cancer, when the cancer has had time to grow and spread. While metastasis can occur in any stage of cancer, it is most common in the advanced stages, where the cancer has had time to spread further and become more aggressive.
What is Metastasis?
Metastasis is the process by which cancer cells spread from their original site to other parts of the body. It usually occurs when cancer cells break away from the primary tumor, enter the bloodstream or lymphatic system, and travel to other areas of the body. Once there, they can form new tumors or invade other tissues.
When Does Metastasis Occur?
Metastasis can occur in any stage of cancer, but it is most common in the later stages when the cancer has had time to spread further and become more aggressive. Metastatic cancer is often more difficult to treat than cancer that has not yet spread. Treatment for metastatic cancer typically involves a combination of chemotherapy, radiation, and/or surgery.
How Can Metastasis Be Prevented?
Metastasis can be prevented or slowed down by early detection and treatment of cancer. This is why regular screening and checkups are important for people at high risk for cancer. Proper treatment of the primary tumor can also help reduce the risk of metastasis. Other methods of prevention include lifestyle changes, such as quitting smoking and maintaining a healthy weight.
