Hi all,
Martin the computerphobe has asked me to ask you this.

How many cancer survivors here had an unknown primary?

This is really worrying him even though our consultant told us that there are 3 types of cancers all curable:
1. primary found immediately
2. primary found after investigative surgery
3. primary not found because the immune system killed the primary but some other cancerous cells sneaked out.

Our consultant is very satisfied but Martin is concerned that it is not really gone, he said it was like trying to fight the invisible man in the dark.

Thanks

Cecilia
