I’m thinking because a CT scan won’t pick up all the cancer cells. In my case it’s serous cancer. It keeps coming back so throw all you have at it? I had 2 recurrences in vaginal vault.
That is why radiation was recommended for me.
Jane my doctor told me that the tiniest micro can not be visible. Radiation is another way to knock cancer out
Tumor biopsies are examined under a microscope
What does provide microscopic views?
