Colon Cancer

What is Colon Cancer?

Colon cancer is when cancer cells along the lining of the large intestine divide uncontrollably, which then causes spreading to the rest of the body.

What are the Symptoms of this Cancer? How does it Impact the People it Affects?

Symptoms of Colon cancer include but are not limited to: Physical discomfort around abdomen, constipation, chronic fatigue, bloating, and unusual weight loss. People with colon cancer often undergo chemotherapy which has a wide array of symptoms that are extremely painful including excessive diarrhea, mouth sores, dry skin (eyelids, feet, hands), weightloss.

How Prevalent is Colon Cancer?

Although the numbers have decreased greatly in the past 30 years, Colon cancer is the second most deadly cancer in the U.S. Each year over 100,000 new cases of Colon cancer is diagnosed in the U.S alone. Colon cancer affects both men and women, although men are at a slightly greater risk.

How is Colon Cancer Diagnosed?

Colon cancer is diagnosed by screening and lab testing patients. People who are 50+, obese, people who smoke, and sometimes family history are at a higher risk. Patients are screened using colonoscopy, which gives doctors a look on the inside of the large intestine. Small clusters of cells called polyps are looked at to see if cells have developed. If it is caught at an early stage, doctors are able to destroy the polyps which is one of the reasons the death rate has decreased in the past 30 years. Although polyps aren't dangerous in general, if they contain cancer cells, that is what causes colon cancer.

What are the possible causes of this type of cancer?

Scientist still aren’t sure what the cause is for most cases of colon cancer, but they understand the movement and growth of the cancerous cells.

  • A healthy cell would grow and divide

  • When the cell is cancerous it is damaged and divides beyond the amount it’s suppose to

  • A cancer cell can infect other tissue around it, destroying the tissue

  • A cancer cell also has the ability to travel to other parts of the body

What are the Treatments? What are the Cures?

There are three primary treatments for different forms of colon cancer. Which treatment you receive greatly depends on which stage the cancer is in.

  • During colonoscopy, if the cancer is small, then it can be removed completely without further treatment

  • You may have to have the part of the colon that holds the cancer and the surrounding tissue removed and tested if the cancer has become too big

  • An operation will be held to relieve pain and symptoms caused by the cancer by weakening a blockade in your colon

What happens at the cellular and molecular level?

Everyone has the potential to have cancer, although some people may never be diagnosed in their life. Almost always is cancer caused by the same sequence that has multiple steps to it.

  • Microbes and parasites that generally come from not well prepared meat can infest an organ although they can also come from other areas

  • Microbes then intercept glucose which was going towards cells and then the microbes release a highly acidic and wasteful toxin in the cells

  • This toxin weakens the cells in the organ making the organ weak

  • The microbes directly and indirectly weaken the immune system

  • A weak immune system cannot kill the cancer cells fast enough so they then grow out of control

  • The core problem of cancer is microbes and parasites however they are other possible causes such filth in the colon which can also weaken the immune system

The articles I’ve read from on the Mayo Clinic website were all written by the Mayo Clinic staff and the credibility of this staff is undoubtable. Every one part of the staff are credible medical physician and most have been involved in the field for over 10 years. For the fact that if the articles that I’ve read from them hold any amount of bias isn’t the case. There are no bias from what I can see and considering that Mayo Clinic is a not-for-profit organization there are no other organizations that they endorse that doesn't help their cause. They delivered on the facts and information on the cancer and did not have a bias agenda. As for the currency, the article is over two years old. However, on their website they hold a database of all the articles they’ve written and are alerted to it. So if there were any big changes or find for colon cancer then Mayo Clinic will surely revise it. For their coverage on this topic, and for many other types of cancer, Mayo Clinic explores the surface and also goes deep in the topic they cover. For cancer they provide tabs on the left side of the page that holds info on what exactly you’re looking for and able to research anything related to the cancer.
