METASTASIS

Metastasis is the spread of a pathogenic specialist from an underlying or essential site to an alternative or auxiliary site in the host's body. The term is often used to refer to the metastasis of a cancerous tumor. The spread of cancer cells from where they originally framed to another part of the body. During metastasis, cancer cells break away from the first (essential) tumor, migrate through the blood or lymphatic system, and structure another tumor in various organs or tissues of the body. The new metastatic tumor is a type of cancerous growth similar to the essential tumor. Cancer occurs after cells are inherited to reproduce quickly and unsafe. This uncontrolled proliferation by mitosis produces an essential heterogeneous tumor. The cells that make up the tumor end up undergoing metaplasia, followed by dysplasia and then anaplasia, creating a malignant phenotype. This malignancy allows invasion to spread, followed by intrusion into a second site for tumorigenesis.
