Metastasis is a process during which the cancerous cells migrate from one organ to another and invade other healthy tissues, converting them into cancerous forms. This process allows cancer cells to spread throughout the body. During metastasis, the organ from where the cancer cells spread is known as primary cancer, and the organ to which these cells invade and cause their conversion into cancer tissue is known as secondary cancer. For example, the spread of cancer tissues from the liver (primary) to the lungs (secondary).
