"Colorectal" refers to the colon and rectum (the two parts of the large intestine). Colorectal cancer can start anywhere in the large intestine as polyps (abnormal growths). Polyps can become cancer over time.What causes it, and who is at risk?
The cause of most colorectal cancer is not known.
These things may increase your risk of getting it:
- Older age (the older your age, the higher your risk).
- A personal or family history of colorectal polyps or cancer.
- Inflammatory bowel disease (ulcerative colitis or Crohn's disease).
- Certain genetic syndromes like FAP (familial adenomatous polyposis) or Lynch Syndrome.
What are the symptoms?
Symptoms may include:
- Blood in your stool
- Stomach pain, aches, or cramps that don't go away
- Unexplained weight loss
NOTE: Many people with colorectal cancer have NO SYMPTOMS.
The best way to lower your risk is to have regular colorectal cancer screening tests starting at age 50. These tests can find polyps, which can be removed before they turn into cancer.
Norovirus is a germ that is a common cause of gastroenteritis.
- Stomach cramping
- Low-grade fever
- Muscle aches
Norovirus is VERY contagious. It is found in the stool or vomit of infected people. You can get infected with norovirus by...
- Eating or drinking things that have norovirus on or in them.
- Touching your mouth after touching contaminated objects.
- Having direct contact with an infected person (for example, sharing food or eating utensils with someone who has it).
In general, children with norovirus have more vomiting than adults with the virus. In most people, symptoms last about 1 or 2 days.Tips to prevent norovirus
- Wash your hands often, especially after using the bathroom or changing diapers, before eating or preparing food, and after touching public surfaces like handrails and doorknobs.
- If you do not have soap, use alcohol-based hand sanitizer.
- Thoroughly clean contaminated surfaces with a bleach-based cleaner.
- Thoroughly wash fruits and vegetables.
- Wash contaminated clothing, bedding and rags with soap and hot water.
