Clinical Information
- Malignant neoplasm of sigmoid colon or sigmoid colon cancer is when there are growths or polyps in the inner lining of the patient’s colon, particularly the sigmoid colon.
- This type of cancer primarily affects people who are 50 years of age or older. However, younger people ranging from 20 to 40 years of age may also be diagnosed with this type of colon cancer, especially if their lifestyle choices increase the risk of developing this disease. Some lifestyle choices that increase the risk are being obese, having a diet that mainly includes red/processed meat, not exercising, and participating in substance abuse, primarily tobacco and alcohol.
- Aside from the aforementioned lifestyle choices, medical conditions may also increase the risk of someone developing colon cancer. Some are inherited conditions, polyps or colon cancer history, and inflammatory bowel disease.
- Though symptoms may not present themselves in the earlier stages of the disease, later on, when the tumor grows, it may cause the patient to experience the following: blood in stool, abdominal pain, bloating, nausea, vomiting, anemia, pelvic pain, unexplained weight loss, loss of appetite, change in bowel habits, and rectal bleeding. Do note that symptoms may vary depending on the tumor’s location.
- Diagnosing colon cancer will require the patient to undergo multiple tests. Among them are blood tests, colonoscopy, X-rays, CT scans, MRI scans, PET scans, sigmoidoscopy, and fecal DNA tests.
- Treatment varies depending on the stage. Generally, however, treatment can be a mix of surgery and chemotherapy.
