Movement of feces (undigested food, bacteria, mucus, and cells from the lining of the intestines) through the bowel and out the anus. Also called defecation.
A partial or complete block of the small or large intestine that keeps food, liquid, gas, and stool from moving through the intestines in a normal way. Bowel obstructions may be caused by a twist in the intestines, hernias, inflammation, scar tissue from surgery, and certain types of cancer, such as cancers of the stomach, colon, and ovary. They may also be caused by conditions that affect the muscles of the intestine, such as paralysis. Signs and symptoms may include pain and swelling in the abdomen, constipation, diarrhea, vomiting, and problems passing gas. Most bowel obstructions occur in the small intestine. Also called intestinal obstruction.
A gene that makes a protein that is involved in sending signals in cells and in cell growth. Mutated (changed) forms of the BRAF gene and protein have been found in many types of cancer. These changes can increase the growth and spread of cancer cells.
A substance that blocks a protein called BRAF. BRAF is a kinase enzyme that helps control cell growth and signaling. It may be found in a mutated (changed) form in some types of cancer, including melanoma and colorectal cancer. Blocking mutated BRAF kinase proteins may help keep cancer cells from growing. Some BRAF kinase inhibitors are used to treat cancer.
The organ inside the head that controls all body functions of a human being. Made up of billions of nerve cells, the brain is protected by the cranium (the bones that form the head). It is made up of three major parts: the cerebrum, the cerebellum, and the brain stem. The cerebrum is the largest part of the brain and controls thinking, learning, problem solving, emotions, memory, speech, reading, writing, and voluntary movement. The cerebellum controls fine motor movement, balance, and posture. The brain stem controls breathing, heart rate, and the nerves and muscles used to see, hear, walk, talk, and eat. The brain stem connects the brain to the spinal cord. The brain and the spinal cord make up the central nervous system.
Cancer that has spread from the original (primary) tumor to the brain.
An imaging method used to find anything not normal in the brain, including brain cancer and cancer that has spread to the brain from other places in the body. A radioactive substance is injected into a vein and pictures are taken to show where the radioactivity collects, indicating an abnormality.
The part of the brain that is connected to the spinal cord.
The part of the brain that is connected to the spinal cord.
Glandular organ located on the chest. The breast is made up of connective tissue, fat, and breast tissue that contains the glands that can make milk. Also called mammary gland.
