Intestinal cancer: Types, Symptoms, Prevent, Treatment

 There are several different types of intestinal cancer, including:

1. Colorectal cancer: This is the most common type of intestinal cancer, and it occurs in the colon or rectum. The colon is the large intestine, and the rectum is the last several inches of the colon. Colorectal cancer is also the third most common cause of cancer deaths in the United States.

2. Anal cancer: This type of cancer occurs in the anus, which is the opening at the end of the digestive tract.

3. Small intestinal cancer: This type of cancer occurs in the small intestine, which is the part of the digestive tract that connects the stomach to the large intestine.

4. Large intestinal cancer: This type of cancer occurs in the large intestine, which is the part of the digestive tract that absorbs water from food and removes waste from the body.

Intestinal cancer symptoms can vary depending on the location of the cancer within the intestine. Some common intestinal cancer symptoms may include:

1. Changes in bowel habits: Persistent diarrhoea, constipation, or other changes in bowel habits that last for more than a few days can be signs of intestinal cancer.

2. Blood in the stool: Blood in the stool can be a sign of many different conditions, including intestinal cancer. Blood in the stool may appear as bright red or dark and tarry.

3. Abdominal pain or discomfort: Pain and discomfort in the abdomen can be signs of intestinal cancer. The pain may be persistent or come and go.

4. Unexplained weight loss: Unexplained weight loss can be a sign of intestinal cancer or other conditions.

5. Fatigue: Fatigue and weakness can also be signs of intestinal cancer or other conditions.

6. Iron deficiency anaemia: Iron deficiency anaemia can occur when intestinal cancer causes bleeding that leads to a low level of iron in the blood.

It is important to note that some people with intestinal cancer may not experience any symptoms at all. This is why regular screening tests, such as colonoscopies, are important for detecting precancerous polyps or early stages of cancer before symptoms occur. If you experience any of these symptoms, it is important to see your doctor for an evaluation.

 The exact causes of bowel cancer are not known, but certain factors can increase the risk of developing this cancer. Here are some potential causes of intestinal cancer:

1. Genetics: While inherited genetic mutations are not among the main causes of intestinal cancer, certain genetic conditions can increase the risk of developing this cancer. Examples include Lynch syndrome and familial adenomatous polyposis (FAP).

2. Age: The risk of developing intestinal cancer increases as a person gets older. Most people who develop this cancer are over the age of 50.

3. Inflammatory bowel disease (IBD): People with IBD, including Crohn's disease and ulcerative colitis, have an increased risk of developing intestinal cancer.

4. Personal or family history of intestinal polyps or cancer: People who have had intestinal polyps or a previous diagnosis of intestinal cancer, or who have a family history of these conditions, may have an increased risk of developing this cancer.

5. Diet: A diet that is high in red and processed meats and low in fruits, vegetables, and whole grains may increase the risk of developing intestinal cancer.

6. Obesity: People who are overweight or obese have an increased risk of developing intestinal cancer.

7. Smoking and alcohol consumption: Both smoking and heavy alcohol consumption can increase the risk of developing intestinal cancer.

Not all people with these risk factors will develop intestinal cancer, and some people with no known risk factors may develop this cancer. Regular screening tests, such as colonoscopies, are important for detecting precancerous polyps or early stages of cancer before symptoms occur. If you have risk factors for intestinal cancer, talk to your doctor about appropriate screening and prevention strategies.

There are several risk factors that can increase the likelihood of developing intestinal cancer. Here are some of the most common risk factors for this cancer:

1. Age: Intestinal cancer is more common in people over the age of 50. The risk of developing this cancer increases as a person gets older.

2. Genetics: Certain genetic mutations can increase the risk of developing intestinal cancer. For example, people with Lynch syndrome or familial adenomatous polyposis (FAP) have a higher risk of developing this cancer.

3. Personal or family history: People who have had intestinal polyps, previous intestinal cancer, or a family history of these conditions are at a higher risk of developing this cancer.

4. Inflammatory bowel disease (IBD): People with IBD, including Crohn's disease and ulcerative colitis, have an increased risk of developing intestinal cancer.

5. Diet: A diet that is high in red and processed meats, low in fruits and vegetables, and low in fibre can increase the risk of developing intestinal cancer.

6. Obesity: People who are overweight or obese have a higher risk of developing intestinal cancer.

Smoking and alcohol consumption: Both smoking and heavy alcohol consumption can increase the risk of developing intestinal cancer. 

While there is no sure-fire way to prevent intestinal cancer, there are several steps you can take to reduce your risk of developing this cancer. Here are some of the most effective ways to prevent intestinal cancer:

1. Get screened: Regular screening tests, such as colonoscopies, can help detect precancerous polyps or early stages of cancer before symptoms occur. Talk to your doctor about when to start screening and how often to have it done.

2. Maintain a healthy weight: People who are overweight or obese have a higher risk of developing intestinal cancer. Maintaining a healthy weight through regular exercise and a balanced diet can reduce your risk of cancer.

3. Eat a healthy diet: A diet that is high in fruits, vegetables, whole grains, and lean proteins can help reduce your risk of intestinal cancer. Avoid or limit red and processed meats and limit your intake of alcohol.

4. Don't smoke: Smoking is a major risk factor for many types of cancer, including intestinal cancer. Quitting smoking can significantly reduce your risk of developing this cancer.

5. Limit radiation exposure: Exposure to high radiation levels can increase the risk of developing intestinal cancer. Limit your exposure to medical radiation, such as CT scans and X-rays, and avoid unnecessary exposure to environmental radiation.

6. Manage underlying conditions: If you have inflammatory bowel disease or other conditions that increase your risk of developing intestinal cancer, work with your doctor to manage these conditions and reduce your risk.

7. Talk to your doctor: If you have a family history of intestinal cancer or other risk factors, discuss appropriate screening and prevention strategies. They can provide guidance and support to help reduce your risk of developing this cancer.

While there is no way to guarantee that you won't develop intestinal cancer, taking these steps can significantly reduce your risk and improve your overall health. 

 If you have symptoms of intestinal cancer, your doctor will likely recommend diagnostic tests to determine if cancer is present. Diagnostic tests may include a physical exam, blood tests, imaging tests (such as CT scans or MRI), or a biopsy of the intestinal lining.

If cancer is present, additional tests will be conducted to determine the stage of the cancer. The stage of cancer is determined by the size and location of the cancer, as well as if the cancer has spread to other parts of the body.

There are four stages of intestinal cancer:

Stage 1: The cancer is limited to the innermost lining of the intestine.

Stage 2: The cancer has grown through the innermost lining of the intestine and into the muscle layer.

Stage 3: The cancer has grown through the muscle layer and into nearby lymph nodes.

Stage 4: The cancer has spread to other parts of the body, such as the liver or lungs.

After treatment, it is important to continue with follow-up care to monitor for any signs of cancer recurrence. This may include regular check-ups with your doctor and imaging tests, such as CT scans or MRIs.

It is also important to maintain a healthy lifestyle, such as eating a balanced diet, getting regular exercise, and avoiding smoking and heavy alcohol consumption. 

 Is intestinal cancer hereditary?
