Detailed explanation-1: -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-2: -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-3: -Stage 4 cancer has spread from its original location to distant parts of the body. It’s sometimes referred to as metastatic cancer. This stage may be diagnosed years after the initial cancer diagnosis and/or after the primary cancer has been treated or removed.

Detailed explanation-4: -Lymph nodes are one of the most common places for cancer to spread. The liver, lungs, and bones are also common sites of metastasis. Certain types of cancer are more likely to spread to certain organs. For example, prostate cancer has a tendency to spread to bones.
