Detailed explanation-1: -Metastasis. In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor.

Detailed explanation-2: -In order to spread, some cells from the primary cancer must break away, travel to another part of the body and start growing there. Cancer cells don’t stick together as well as normal cells do. They may also produce substances that stimulate them to move.

Detailed explanation-3: -The most common type of cancer on the list is breast cancer, with 290, 560 new cases expected in the United States in 2022. The next most common cancers are prostate cancer and lung cancer.

Detailed explanation-4: -This means that the cancer cells can travel far from the original tumor and form new tumors when they settle and grow in a different part of the body. Metastases can also develop when cancer cells from the main tumor break off and grow in nearby areas, such as in the liver, lungs, or bones.
