Detailed explanation-1: -As a cancerous tumor grows, the bloodstream or lymphatic system may carry cancer cells to other parts of the body. During this process, the cancer cells grow and may develop into new tumors. This is known as metastasis.

Detailed explanation-2: -In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.

Detailed explanation-3: -Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis.

Detailed explanation-4: -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-5: -Localized-Cancer is limited to the place where it started, with no sign that it has spread. Regional-Cancer has spread to nearby lymph nodes, tissues, or organs. Distant-Cancer has spread to distant parts of the body.
