Detailed explanation-1: -The spread of cancer cells from the place where they first formed to another part of the body. 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-2: -Rather, cancer has developed in one organ and spread to other areas. When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body.

Detailed explanation-3: -If they travel through the lymph system, the cancer cells may end up in lymph nodes. Most of the escaped cancer cells die or are killed before they can start growing somewhere else. But one or two might settle in a new area, begin to grow, and form new tumors.

Detailed explanation-4: -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.

Detailed explanation-5: -"In general, cancers that have spread to the lymph nodes are typically stage 2 or 3, ” says Juan Santamaria, MD, Nebraska Medicine surgical oncologist. “Many of these cancers are still treatable and even curable at this stage.
