Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage when it may be easier to treat. Lung cancer may have spread by the time a person has symptoms. One reason lung cancer is so serious is because it usually is not found until it has spread and is more difficult to treat. Screening may provide new hope for early detection and treatment of lung cancer. Scientists study screening tests to find those with the fewest risks and most benefits. They look at results over time to see if finding the cancer early decreases a person's chance of dying from the disease.

Bone marrow biopsy and bone marrow aspiration are procedures to collect and examine bone marrow — the spongy tissue inside some of your larger bones. Bone marrow biopsy and aspiration can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use these procedures to diagnose and monitor blood and marrow diseases, including some cancers, as well as fevers of unknown origin. Bone marrow has a fluid portion and a more solid portion. In bone marrow biopsy, your doctor uses a needle to withdraw a sample of the solid portion. In bone marrow aspiration, a needle is used to withdraw a sample of the fluid portion.

Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine (colon). Irritable bowel syndrome commonly causes cramping, abdominal pain, bloating, gas, diarrhea and constipation. IBS is a chronic condition that you will need to manage long term. Even though signs and symptoms are uncomfortable, IBS — unlike ulcerative colitis and Crohn's disease, which are forms of inflammatory bowel disease — doesn't cause changes in bowel tissue or increase your risk of colorectal cancer. Only a small number of people with irritable bowel syndrome have severe signs and symptoms. Some people can control their symptoms by managing diet, lifestyle and stress. Others will need medication and counseling.
