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.

Leptomeningeal metastases

Coping with secondary cancer

Coping with secondary cancer can be very difficult. Getting the help and support you and your family need can help.

Secondary cancer resources and support

There are organisations, support groups and books to help you cope with symptoms and side effects caused by secondary cancer and its treatment.
