Have vs Had

At what point in my journey can I use the phrase “I had cancer”? Is there any specific time that you can switch a “have” to a “had” when you have stage 4? Since the cancer cells in my body are just floating around like dust particles, I wonder if I will ever be able to speak of cancer in a past tense. If I forget about the microscopic cancer cells and just go by what we can see, can I use the term after my first clear scan? Or do I have to wait till that all coveted 5 year mark to finally say, “I had cancer”. Even when that time comes, is that a description I would want to define myself? I am so much more than this disease, but yet it seems to be in the top five of words used to describe myself these days.

Having a “planner” personality it is very difficult to throw all of my papers up in the air and just let life unfold as it may. I am always looking years ahead but now I find myself only being able to plan 3 months at a time. Right now I am not even sure what will happen next month as my next body scan is January 27th. That will determine a yay or nay to surgery on my lung. However if that scan is clear then in February, am I stepping into the “had” zone? Maybe it is when I am off chemo and all I have is scars as evidence of my battle with cancer. Maybe I should stop thinking so much.
