Colon Cancer

It has been reported that more of the cancer deaths in America are result of lungs cancer and the second place is occupied by colorectal cancer. This disease or sort f cancer goes undiagnosed because of embarrassment, denial and fear. A misconception is also related with this disease and that says “colon cancer strikes more men then women”. However, estimates and evaluations have shown that after breast cancer and lung cancer, colon cancer strikes more women and is the third leading cancer to cause death in women. The frequency for disease development is men and women, is almost equal.

Regional differences however are observed in the mortality of the disease throughout the Americas. Northeast of America has greater mortality as compared to any other area of Americas. More African-American are dieing of this disease every year.

This disease is preventable and is one develop it can also be treated. Screening for this disease can lower the death rate by sixty percent for colon cancer.

Colon is the last portion of digestive tract and is almost twelve to fifteen centimeters long. This is the location where waste materials are accumulated, collected and hardened before they expelled out of body. Studies have revealed that waste material remain at this place for some two days before expelling out.

The cancer is defined as abnormal production of cells forming malignant tumors. If these tumors are formed in the large intestine or colon then they are called Polyps. These polyps sometimes are benign and sometimes malignant. Almost twenty percent of American adult population has these polyps in their large intestine.

Polyps are of several types out of which three, which never develop in colorectal cancer, are:

  • inflammatory polyps
  • hyper plastic polyps
  • lymphoid polyps

One, which develops in colorectal cancer, is named as adenomas polyps and forms a cancer by undergoing cancerous changes. When they are transformed in to cancer, they are called “adeno-carcinomas”. The time taken for this transformation from adenomas in to adencarcinomas usually takes five to ten years. Therefore, proper screening can cut down chances for cancer development in colon region.

Some other tumors are also there which contribute to the cancer formation. They are:

  • carcinoid tumors
  • gastrointestinal stromal tumors etc

Below I have mentioned risk factors for the development of colon cancer but it is also to be mentioned here that there are two sorts of factors i.e. high risk factors and average risk factors. Let us, first know risk factors and later we would differentiate these risk factors in to kinds.

  • Family and personal history
  • Age
  • Diet
  • Race
  • Style of living

The high risk factor is “family and personal history” while all other factors are average risk factors.

Tests, which are used to screen tumors in colon, are:

  • A fecal Occult Blood Test
  • flexible sigmoidoscopy
  • fecal immunochemical test
  • double contrast barium enema
  • colonoscopy
  • virtual colonography
  • Digital rectal examination

Symptoms for the colon cancer include:

  • bowel habits are changed
  • feeling for moving out bowls even if you had it just a minute before
  • urgency for bowel movement
  • bloody stool
  • pain in stomach
  • fatigue

Doctor must be contacted immediately if you experience set of two symptoms.
