I have been diagnosed with what is known as an occult cancer. They think it is breast cancer due to the make up of the cells but although it has spread to my lymph nodes which is the secondary source they cannot find the primary source. I have had numerous mammograms and every scan there is to have but they still cannot find where the primary source is in my breast. I have now had all my lymph nodes removed and have just had my first dose of chemotherapy (FEC) I will then have radiotherapy followed by one year of herceptin as my cancer has come back as Her 2 positive. This has been a nightmare from the start as it has been going on since April trying to find the primary source. I just wondered if anyone else was in a similiar situation.
