What happens to a cancer patient after treatment is complete?
At some point after cancer treatment is complete, a patient's main medical care may eventually move back to their primary care physician. Cancer survivors often say they feel lost in this transition. I recommend each patient takes time with their oncologist to clarify the follow-up schedule of visits and tests recommended for the future.
What happens to tumor cells after they are killed?

Nothing happens to cancer cells during chemo, that doesn’t happen to all cells in the body that need to replicate. Chemotherapy simply prevents cells from starting the mitosis process, when it works, in the hope that the tumor’s growth will slow down.
What happens to cancer cells that are damaged by radiation therapy?
Most, hopefully, all the radiated cells suffer DNA damage that they are unable to repair (healthy cells are also damaged, but are better able to repair the damage). This will stop their reproduction and thus tumor growth and spread. Eventually most will die (apoptosis) and be swept out of the body.

How do cancer cells die off?
When normal cells reach the end of their useful life, they self-destruct. This suicide process is called programmed cell death or apoptosis. But cancer cells have a defective self-destruct program. They make too much of a molecule called BCL-2, which gobbles up the chemical messengers that activate cell suicide.

Do we all have cancer cells?
No, we don't all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn't mean they're destined to become cancer.
Can a cancer/tumor shrink on its own?
The process is typically called “spontaneous regression” or “spontaneous remission,” and a considerable body of literature confirms that cancer and benign tumors do indeed “disappear” and, in exceptional cases, patients are cured of the disease — in which case the phrase “miraculous healing” is sometimes invoked.
