Neoplasm is the abnormal growth that develops as the result of the mutation. These abnormal cells can continue to proliferate and develop as a tumor. The neoplasms can either be cancerous (malignant) or noncancerous (benign). Unlike the benign tumor, the cancerous growth can grow aggressively by invading the surrounding tissues and spreading to other parts of the body. Intestinal cancer is the cancerous growth that develops in the small or the large intestines which are a part of the digestive system. Some of the intestinal neoplasms include small intestine cancer and colorectal cancer.
Small intestine cancer
This is a rare type of cancer where the abnormal growth occurs in the tissues of the small intestine. The five types of small intestine cancer include adenocarcinoma, carcinoid tumors, sarcomas, gastrointestinal stromal tumor and the lymphomas. Adenocarcinoma develops in the lining of the small intestines and is the common type of small intestine cancer which can grow and block the intestine. Some of the risk factors associated with developing the small intestine cancer include consuming food high in fat, having conditions such as celiac disease, crohn’s disease or individuals with familial adenomatous polyposis (FAP). Some of the symptoms of small intestine cancer include unexplained weight loss, abdominal pain, blood in the stool and the presence of a lump in the stomach. The treatment options are based on whether the surgical removal of the tumor is possible by determining if it is primary cancer (not spread) or metastatic cancer (spread to other parts of the body). The three types of treatment for small intestine cancer include surgery, radiation therapy and chemotherapy. During the surgery, the removal of a part or the entire organ containing the cancer is possible. Alternatively, the surgical procedure allows the food in the small intestine to bypass the tumor when it cannot be removed. Radiation therapy uses high-energy x-rays or other types of radiation to destroy the cancerous cells or prevent the growth of cancer. The chemotherapy uses drugs to stop the growth of cancer. After the treatment, the follow-up tests may be necessary to determine if the condition has changed or if cancer has recurred.
Colorectal cancer
The large intestine consists of the colon and the rectum. The colorectal cancer is the abnormal growth that develops in the lining of the large intestine. The adenocarcinomas are the most common types of colorectal cancer that develop in the cells that produce and release the mucus and other fluids. Colorectal cancer can also develop from the growth known as polyp which develops in the inner lining of the colon or the rectum. Early detection and the removal of the polyps can prevent colorectal cancer. Some of the symptoms of colorectal cancer include constipation or diarrhea, blood in the stool, weight loss, fatigue, nausea, vomiting, feeling the bowel does not completely empty and feeling bloated. As the initial stage may not present any symptoms, individuals over the age of 50 should get screened. Some of the treatment for colorectal cancer includes surgery, radiation therapy and chemotherapy.
