Not to throw a monkey wrench into this discussion topic
( we have had this discussion a few times over the years
AND various centers and studies will have SPECIFIC definitions of their "survivor" terms and conditions when publishing stats etc.
BUTT .... you just KNOW there is at least one !!!! I offer the following :
1. CRC tumors tend to be slower growing ... SO when diagnosed you have probably been surviving
with having cancer for at least a few years
2. diagnosis, whether by confirmed pathology from a biopsy or surgery, imaging, clinical "impression" gives a starting point from which most folks would agree "You have THIS and you are surviving
3. Surgical removal of tumor = cancer is gone, so now you are surviving
4. During chemo, chemo/rad and other modalities given prior to surgical tumor removal = we know you have this BUTT ...
NOW you are surviving
during this whole process
5. diagnosis, chemo, chemo/rad, surgery, healing, NED = all done / good to go = you are now surviving
AFTER the whole process
personally, my take is with the date of confirmed diagnosis ...you KNOW you have cancer and moving forward
EVERYTHING you do ...IS as a SURVIVOR.
Prior to a diagnosis you are a patient who may have suffered some minor-major issues.
AFTER a definitive diagnosis you ARE A CANCER SURVIOR !!!
I do see the rationale of using a curative surgery date, where one exists ... BUTT ...
there are many folks who do not get to curative surgeries and still survive,
many who go through all kinds of treatments and still survive.
BUTT .... BUTT
everyone I have known, HAS had a diagnosis date
