Detailed explanation-1: -Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis.

Detailed explanation-2: -Nearly all types of cancer have the potential to metastasize, but whether they do depends on a number of factors. Metastatic tumors (metastases) can occur in three ways: They can grow directly into the tissue surrounding the tumor. Cancer cells can travel through your bloodstream to distant locations in your body.

Detailed explanation-3: -For example, here are some common types of cancer and where they commonly metastasize: Breast cancer tends to spread to the bones, liver, lungs, chest wall, and brain. Lung cancer tends to spread to the brain, bones, liver, and adrenal glands. Prostate cancer tends to spread to the bones.

Detailed explanation-4: -Metastatic cancer is a cancer that has spread from the part of the body where it started (the primary site) to other parts of the body. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system.
