Tumor markers: Cea is a tumor marker it does not occur with all colon cancers but the fact that it dropped so abruptly is a positive sign. The marker has the ability to be used to monitor for recurrence. This does by no means indicates you are done. There are a number of treatments for colon cancer and you should recruit the serviceces of a board certified medical oncologist for an opinion on tx options.

That is good: That is a good thing. We use CEA for surveillance. 1.8 is a very good number. Your docs will follow the CEA now to see if it rises as a way to detect recurrence.

How can you get bladder cancer if you're constantly urinating?

In other ways.: The development of bladder cancer has little to do with the frequency of urination. It has everything to do with changes to the lining of the bladder, mostly due to exposure to toxins in the urine, such as from cigarette smoke & industrial chemicals. Inherited genetic factors play a role as well. For those that have developed bladder cancer, one of the symptoms can be frequent urination.

It depends: Results depend upon the stage of cancer. It is active for the adjuvant treatment and in metastatic disease. The side effects can include nausea and diarrhea. Occasionally there can be some blood count issues. The other side effect can be cold related temporary nerve injury that lasts a very short time. There also is a more long term nerve injury. Most people do tolerate this well. Hope this helps.

Probably not: In japan they showed it could happen, but with 40% peroxide. It's illegal in the usa, here we only get up to 3-5% no proof here.
