I really don't know.
I have seen several hundred people die with advanced Colon carcinomas,
and every one was different. Since Colon CA does not often spread to bones,
we rarely see bone pain as we do in breast and prostate carcinomas.
The liver is the most common place Colon CA's go, and patients with liver failure
are usually not conscious when they reach the last stage before death.
Lung metastases do occur, but I have never seen a patient cough up blood
(hemoptysis) with Colon cancer. I have seen five patients with primary
lung cancer cough up blood and die quickly from exsanguination (blood loss).
There are of course other causes for hemoptysis.
