Bowel cancer

 

Many of the colorectal cancers are occurring due to a majority of wrong lifestyle factors and an increase in the age. A very small number of the cases are reported and diagnosed which have a hereditary occurrence and thus form a genetic disorder. A few risk factors are diets, present obesity, tobacco smoking, and insufficient presence of physical activity. A few dietary risk factors include consumption of red mead, consumption of processed meat as well as intake of alcohol at times.

The primary factor can also be counted as presence of inflammatory bowel disease including the Crohn’s disease and also the ulcerative colitis. The inherited conditions which can result in the colorectal or the bowel cancer can be adenomatous polyposis (familial) and the non-polyposis colon cancer (non-hereditary). The start of this type of cancer is as a benign tumor and then it results in to the formation of a cancerous tumor.

Signs and symptoms of Bowel Cancer

The symptoms involved are depending on the location of the tumor in the present bowel. Also, it depends upon the spread anywhere else in the body.

Some classic signs include:

  • Constipation which may worsen at times
  • Stools comprising of blood
  • Decreasing in the caliber of the stools (thickness)
  • A loss in the appetite of a person
  • Causing of nausea and vomiting in the patients over 50 years of age
  • Rectal bleeding and anemia in the patients over 50 years of age

Diagnosis of Bowel Cancer

The diagnosis of this kind of cancer is done from the sampling of the areas of the suspicious colon possible for the development of the tumor.  It might also depend on the adequate location of the lesion. The disease extent further depends upon the chest CT scan, the Ct scans of the abdomen and also the pelvis. Some other tests may include like the PET and the MRI which are further used in some cases.

A technique called as Colon cancer staging is done as the next step and it is based on TNM system. This TNM system is determined by the initial amount of the spread of the tumor and the involvement of the lymph nodes. The extent of the metastatic disease is also involved.

Treatment of the Bowel Cancer

If the cancer is caught at an early stage, the cancer can be cured via the means of a surgery. The surgical removal is done with the adequate margining of the cancer. This can be done and at times is done via an open laparotomy.

Chemotherapy and radiation therapies are some other used techniques in addition to the surgeries or prior to the surgeries. Sometimes a combination of both is done in order for an effective treatment.
