Colorectal Cancer

Definition

Colorectal cancer is the second most common visceral malignant neoplasm. It's the third most common cancer in women and the second leading cause of cancer death. The colon and rectum are part of the large intestine. Colon and rectum cancers sometimes referred to together as colorectal cancer and it arise from the lining of the large intestine. When cancer arises from the lining of an organ like the large intestine, it is known as carcinoma. Incidence is equally distributed between men and women. Colorectal cancer tends to progress slowly and remains localized for a long time. Consequently, it's potentially curable in about 90% of patients if early diagnosis allows resection before nodal involvement. With improved diagnosis, the overall 5-year survival rate is about 60% for adjacent organ or nodal spread, and greater than 90% for early, localized disease.

Causes of Colorectal Cancer

The exact cause of colorectal cancer is unknown. But some other factors that may cause colorectal cancer such as:

• Other diseases of the digestive tract
• History of ulcerative colitis
• Familial polyposis

Symptoms of Colorectal Cancer

Treatment of Colorectal Cancer

• Other treatments recommended to prevent colorectal cancer include a diet such as high in fruits and vegetables, low in red and processed meats, high in calcium and folic add.
• The most effective treatment for colorectal cancer is diagnosed is surgery to remove the malignant tumor and adjacent tissues and any lymph nodes that may contain cancer cells.
• You can also used the drugs in such treatment commonly such as  fluorouracil with levamisole, methotrexate, or streptozocin.
• The risk was also reduced in women who took a multivitamin with folic add for more than 15 years. However, it may take more than a decade for aspirin use to benefit and may cause gastric ulcers and hemorrhagic strokes. Thus, these aren't substitutes for regular colorectal cancer screening.
• You can also use another treatment such as radiation therapy induces tumor regression and may be used before or after surgery or combined with chemotherapy, especially fluorouracil.
