suolistosyöpien

Suolistosyöpien, commonly referred to as colorectal cancer in English, encompasses a range of malignancies that originate in the colon or rectum. These cancers typically begin as small, non-cancerous growths called polyps, which can develop into cancer over time. The vast majority of colorectal cancers are adenocarcinomas, meaning they arise from the cells that line the colon and rectum. Risk factors for developing suolistosyöpien include older age, a personal or family history of colorectal cancer or polyps, certain inherited genetic syndromes like familial adenomatous polyposis (FAP) and Lynch syndrome, inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, and lifestyle factors like a diet low in fiber and high in red and processed meats, physical inactivity, obesity, smoking, and excessive alcohol consumption.

Symptoms can vary and may not appear until the cancer is advanced. Common signs include a change in bowel habits, such as persistent diarrhea or constipation, blood in the stool, rectal bleeding, abdominal discomfort, cramping, or pain, a feeling of incomplete bowel emptying, and unexplained weight loss. Many of these symptoms can also be caused by other, less serious conditions, making medical evaluation crucial.

Diagnosis typically involves a colonoscopy, a procedure where a flexible tube with a camera is inserted into the rectum to examine the colon. Biopsies of suspicious polyps or tissue can confirm the presence of cancer. Treatment options depend on the stage of the cancer and may include surgery to remove the tumor, chemotherapy, radiation therapy, and targeted therapies. Early detection through regular screening is key to improving outcomes for suolistosyöpien.
