Causes of Colorectal Cancer and Treatment of Colorectal Cancer

Sunday, December 27, 2009 6:37:00 AM Posted by Cancer Centers

Colorectal cancer, also called colon cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix. It is the third most common form of cancer and the second leading cause of cancer-related death in the Western world. Colorectal cancer causes 655,000 deaths worldwide per year, including about 16,000 in the UK, where it is the second most common site (after lung) to cause cancer death.[1] Many colorectal cancers are thought to arise from adenomatous polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time.

Symptoms of Colorectal Cancer
Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they'll likely vary, depending on the cancer's size and location in your large intestine.

Abdominal discomfort (e.g., pain, bloating, cramping, fullness)
Change in bowel habits
Constipation or diarrhea
Narrow stools
Nausea and vomiting

Most of these symptoms are more likely to be caused by conditions other than colorectal cancer, such as infection, hemorrhoids, or inflammatory bowel disease. Still, if you have any of these problems, it's important to see your doctor right away so the cause can be found and treated, if needed.

What Are the Risk Factors for Colorectal Cancer?
A risk factor is anything that affects your chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer, and smoking is a risk factor for cancers of the lungs larynx, mouth, throat, esophagus, kidneys, bladder, colon and several other organs.

Diabetes
Genetic disorders such as familial polyposis syndromes and hereditary non-polyposis colon cancer syndrome (HNPCC)
Inflammatory bowel disease (e.g., ulcerative colitis, Crohn's colitis, granulomatous colitis)
Personal history of intestinal polyps or colorectal cancer
Alcohol
Research has indicated that alcohol increases colorectal cancer risk.

Surgery is the treatment of choice for colorectal cancer. Treatment depends on the stage of the disease and the overall health of the patient. Given before surgery, radiation may reduce tumor size. This can improve the chances that the tumor will be removed successfully.

Laparoscopic surgery -- Also called "keyhole surgery," this innovative approach is being used for some patients with colon cancer. During the procedure, a lighted tube, called a laparoscope, and special instruments are placed inside the body through a few small incisions in the abdomen, rather than one large one. The surgeon is then guided by the laparoscope, which transmits a picture of the intestinal organs on a video monitor and then removes diseased areas of the intestines. Laparoscopic surgery for colon cancer offers an alternative and many advantages to standard surgery, including less pain and a shorter recovery period.

Side Effects of Radiation for Colorectal Cancer
Colorectal cancer can be cured in most cases, when it s diagnosed in early stages. It is the medical oncologists, gastroenterologists, radiation oncologists and surgeons, who specialize in treating such cancers in women.

Colorectal cancer may be treated depending upon the exact location of the tumour present, its stage and size. Although surgery and chemotherapy (radiation therapy) are the most common treatment methods, many women receive a combined treatment of both these methods. However, recent studies show that there are many side effects of radiation for colorectal cancer.

Radiation Therapy for Colorectal Cancer
Radiation therapy uses high energy rays for killing cancer cells. In fact, it affects the cancer cells lying only in the affected area. Two types of radiation therapies, namely the internal radiation and external radiation, are used for treating colorectal cancer.

Side-effects of Using Radiation Therapy
Although radiation therapy has been mostly successful in the treatment of colorectal cancer, there are many side effects of this technique. These side effects usually depend on the part of the body and the dose of radiation given to the patient. Some common side effects of radiation for colorectal cancer treatment are vomiting, hair loss, extreme tiredness, bleeding, easy bruising and increased susceptibility to different infections.

Women undertaking radiation therapy may experience symptoms like vomiting, nausea, bloody stools, urinary discomfort and diarrhoea. The skin where radiation is given may even become tender, dry or red.

Radiation therapy may also cause alopecia (hair loss) in the area, where treatment is carried out. Many women have experienced the side effect of having low white blood cell counts when they have undergone radiation therapy for colorectal cancer. However, this side effect of having low levels of WBC due to radiation is comparatively rare. These cells prevent bleeding and fight your body infection. Radiation therapy can even affect your ability to have children (the same is in the case of your part, if he undergoes the therapy). Some of the other possible side effects resulting from radiation therapy may include discomfort or pressure in the excretory region, burning sensation during urination, fatigue, skin irritation, abdominal cramping, frequent bowel movements and nausea. However, these side effects are temporary, as they tend to resolve after the termination of radiation therapy for colorectal cancer.

Measures for Controlling Side Effects of Radiation Therapy
Although these side effects vary with different patients, they can be controlled by using different medications and inflicting changes in your diet. Do not wear tight clothes and avoid scrubbing, rubbing and putting adhesive tapes on the skin where treatment is done.

Take special care to protect your treated skin from direct sunlight. Since your skin becomes very sensitive during this time, cover it with a dark cloth if possible before going out.
