A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Most cancers develop at their primary site but then go on to metastasize or spread to other parts of the body. These further tumors are secondary tumors.
Which cancer has highest recurrence rate?

How do you know where cancer is from?
Tests on the tissue sample
They might use immunohistochemistry (IHC) tests, which look for particular proteins on the surface of the cancer cells. These tests can sometimes tell which type of cell the cancer started in.
Is primary cancer curable?
When they are first diagnosed, these cancers have already spread beyond the site where they started. This means that the types of treatments that are most likely to be successful, such as surgery or radiation therapy, are not likely to result in a cure in most cases.
Can malignancy be cured?
There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes. Many others are treated for cancer and still die from it, although treatment may give them more time: even years or decades.
