What Is Colorectal Cancer - Causes And Symptoms Of Colon Cancer

Colorectal cancer is one of the major causes of death in the USA. Colon cancer affects older adults in the majority, but it can occur at any stage of life. US-based research has shown that 5% of people will develop colorectal cancer during their lifetime. Research has shown that by the advanced techniques it is now possible to fight against the colon cancer and day by day the death rate has been falling gradually.

Symptoms of colon cancer

It is very rare to experience any symptoms in the early stage of colon cancer. If someone experiences symptoms during the early stages, the may include:
  • Sudden change in the bowel movement.
  • Constipation.
  • Diarrhea.
  • Changes in stool color.
  • Fatigue or weakness.
  • Abdominal pain or cramps.

  • Diverticulosis.
  • Vomiting.
  • Bloating.
  • Shortness of breath.
  • Unexpected weight loss.
  • Nausea and vomiting.
  • The sensation of incomplete evacuation after a bowel movement.

Causes of colon cancer

The causes of colon cancer are not exact as per the research information. But here are some factors which can increase the risk of colon cancer such as:

1. Age

Colorectal can be diagnosed at age of life but research has shown that the majority of people with colon cancer are older than 50-60 age. The chances of getting colon cancer increases as people get older. It does not mean that in young and adult people, colon cancer can not occur.

2. Race

Colon cancer is the most common type of gastrointestinal cancer and 2nd leading cause of cancer death in Africa and America. Research has shown that colorectal cancer is very rare in native African populations, less than 1% per 100,000 populations, compared with 65-68 per 100,000 for African Americans. They suggest that it is because of the difference in environmental influences such as diet.

3. Diet

Some study has shown that diets which are high in red meat, processed meat and very high in fats, refined flour, and sugary drinks can increase the risks of colon cancer. People who don't eat a healthy diet and always prefer to eat unhealthy foods can easily increase the chances of colon cancer so you need to eat some healthy foods to prevent the risk of colon cancer.

4. Polyps

Most of the colon cancer patients develops it in colorectal polyps. Removing colorectal polyps can help to prevent the chances of colon cancer. There are 2 types of polyps which are found in colon and rectum such as :

  • Adenomatous polyps

This type of polyps in the colon and rectum are benign growths and increases the chances of colon cancer. Polyps are larger than 1 cm in diameter and increases the risks of colorectal cancer.

  • Hyperplastic polyps

It is very rare to have colon cancer because of hyperplastic polyps. Large hyperplastic polyps on the right side of the can increase the chances of colon cancer. It is very important to remove the polyps in the colon during the early stage of the colon otherwise it can turn into malignant colon cancer.

5. Genes

The extreme growth of cells can damage the genes and can change the DNA. There are lots of inherited conditions which can cause colon cancer such as :
  • FAP or familial adenomatous polyposis.
  • AFAP or attenuated familial adenomatous polyposis.
  • Gardner syndrome.
  • MYH associated polyposis.
  • Juvenile polyposis syndrome.
  • Lynch syndrome.
It is not necessary to have colon cancer with this type of genetic features unless an environmental factor triggers it.

6. Habits

Some particular unhealthy habits can help to increase the chances of colon cancer such as eating unhealthy foods without limitations, drinking alcohol excessively regularly, smoking cigarettes regularly, Eating processed foods, etc.

7. Diseases

Some risky and serious diseases can help to increase the chances of developing colon cancer such as high blood pressure, kidney damage, blood sugar, heart diseases, liver damages, major surgeries, etc. These type of serious health problems can increase the chances of colon cancer.

When to see a doctor ?

If you are experiencing all the symptoms of colorectal cancer, then seek immediate medical treatment with your doctor. Your doctor will carry out a complete physical examination and may ask about your and your family's medical history because it is very important to know your past medical health. Here are some medial techniques and your physician may use these techniques to know the condition of colon cancer and to identify the stage of cancer:

1. Colonoscopy

Your physician may order to do a colonoscopy to examine the large intestine (colon and rectum). This test is basically used to evaluate gastrointestinal symptoms. During the colonoscopy procedure, your doctor will insert a long and flexible tube with a CCD camera or fiber optic camera on one end into the rectum to inspect the inside of the colon.

The doctor may strictly suggest following a proper special diet for 24-48 hours before the colonoscopy. By the colonoscopy, if your doctor finds polyps in the colon, then a surgeon will remove the polyps and may refer for biopsy.

2. Blood test

It is not possible to examine the stage of colon cancer and also no blood test can if someone has colon cancer. But your doctor may test your blood for the overall health. Overall health conditions may help to know the condition of the colon cancer.

1. For a Polypectomy, if your cancer is small then your surgeon may be able to remove the polyp during the colonoscopy. This process is usually done by passing a wire loop through the colonoscopy to cut the polyp off the wall of the colon with the help of an electric current.

2. If you have large polyps then your doctor might be removed during the process of colonoscopy by using some special tools to remove the large polyps and a minimum amount of inner lining of the colon in the process of endoscopic mucosal resection.

2. Chemotherapy

Chemotherapy is a very advanced process to destroy cancer cells with the help of drugs. Chemotherapy targets any rapidly dividing cells, including the healthy cells. The therapy helps to reduce the symptoms of colon cancer. Chemotherapy surgery has some side effects such as:
  • Hair loss.
  • Nausea.
  • Headache.
  • Vomiting.
  • Fatigue.
