What Is The Difference Between Prostate And Colon Cancer
None: Colon cancer grows within the lumen of the bowel until a population of invasive cells spread to serosa and then nodes. It is probably secondary to a polyoma virus. Prostate Ca which is hormonally controlled probably arises from the MMTV virus entering the Wnt-1 gene to induce transformation. This same virus effects breast Ca and men married to women with Br Ca get more prostate Ca. ...Read more
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Chemoresistance: In metstatic colorectal cancer combinations of chemotherapy utilized. Drug combos such as FOLFOX are employed. With a poor response, immunotherapy is added such as the VEGF receptor antibodies or those targeting epidermal growth factor receptors like Erbitux and Vectibix (panitumumab). If the standard or wild type Kras is present in mets, there is a fairly good response but neg activity in mutated Kras. ...Read more
How can you tell the difference between hemmorhoids and colon cancer? Even though the symptoms are very similar, what are the major differences?
Can be difficult: GREAT question although if we are talking about you it would be very unusual for a 19 yo to have colorectal cancer. The point is it really is almost impossible to know for sure and therefore everyone who has rectal bleeding or a change in bowel habits should see a provider even though the most common cause of both of these is not cancer. ...Read more
Survival, but.....: Used to be, the short answer was simply survival risk with stage 1 having the best prognosis and stage IV the worst. While stages 1/2 still have the highest survival rates but improved surgical techniques and chemotherapy and i'd add lifestyle changes, have leveled the playing field greatly. Colon cancer, even advanced is often quite treatable. ...Read more

Both: Can bleed and cause changes in stool caliber or pattern. Getting a colonoscopy should not require a long wait time. Check with your pcp mfor a referral to another doctor performing colonoscopies that may have a shorter wait time. Being 23 yo, less likely colon cancer. Do not be scared of the unknown and see a colon and rectal surgeon for evaluation in office. ...Read more
Is there a difference in prognosis being diagnosed with stage 4 colon cancer and being diagnosed stage 3 And then liver metastases was found on scan?
Liver: Metastases would indicate stage 4 disease.Get a more detailed answer ›
Can a person live up to 5 years does it make a difference if you were diagnosed stage IV colon cancer than if were stage III but now hav a liver met?
No diff: The prognosis of someone diagnosed today with a liver metastasis of a colon cancer diagnosed a few years ago is not different from that of someone presenting today with newly diagnosed liver mets and primary colon cancer. Five year survival is not the rule, unfortunately, but I have seen many patients whose life exceeded five years after such a diagnosis. Treatment is improving rapidly. ...Read more

What kind of mets:
It depends what kind of metastases we are talking about.
if the spread to the lymph nodes, surgery and chemotherapy, and possible radiation therapy could be very helpful.
if the spread to the liver the prognosis is less optimistic, unless the metastases are able to be resected.
other metastases are less promising in spite of chemotherapy and radiation therapy. Like bone and brain. ...Read more

Colon mets: Not having your chart and you in front of me makes it very hard to give you an accurate idea on prognosis. When chemo is started, that means your CA cells have gone beyond the boundaries which would have made txing it simple. The simpler the tx, the better the prgns. The harder the tx, the worse the prgns. On a positive note, f/u with your docs, stay faithful, and you might get a pleasant surprise ...Read more
What would b classed as terminal colon cancer, ie how many tumors (mets) in the body, how big etc?
Organ failure: Number and size of lesions does not determine terminal disease. Many colon lesions recurr in mid abdomen as extensive lesions producing bowel obstruction.

When end organ failure develops that can't be relieved by colostomy or liver replaced to produce jaundice that can't be relieved by stent then patient is entering terminal state. ...Read more
Not fast: Cancer is thought to spread over several weeks-months of time, not days to weeks. As such, the commission on cancer has guidelines for treatment that cover 7-21 days from presentation to treatment. That is not to say that there are not unusual cases of cancer that seem to be remarkably aggressive, colon cancer is usually not one of them. ...Read more
