A primary cancer is where a cancer starts. Sometimes cancer cells can break away from the primary cancer and settle and grow in another part of the body. This new cancer growth is called secondary cancer. Secondary cancers are also called metastases.
Secondary liver cancer is when a cancer that started somewhere else in the body has spread to the liver. It is also called liver metastases.
Secondary lung cancer is when a cancer that started somewhere else in the body has spread to the lungs. It is also called lung metastases.
Secondary bone cancer is when a cancer that started in another part of the body has spread to the bones. It is also called bone metastases.
Secondary brain cancer is when a cancer that started in another part of the body has spread to the brain. It is also called brain metastases.
Leptomeningeal metastases mean cancer cells have spread to one of the membranes that surround the brain.
Coping with secondary cancer can be very difficult. Getting the help and support you and your family need can help.
