CANCER - COLON |
|
Cancer that begins in the colon is called colon cancer, and cancer that begins in the rectum is called rectal cancer. Cancers affecting either of these organs may also be called colorectal cancer.
When colorectal cancer spreads outside the colon or rectum, cancer cells are often found in nearby lymph nodes. If cancer cells have reached these nodes, they may also have spread to other lymph nodes, the liver, or other organs.

CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

CANCER - LIVER |
|
Hepatocellular carcinoma (HCC, also called hepatoma or liver cancer) is a primary malignancy (cancer) of the liver. Most cases of HCC are secondary to either hepatitis infection (usually hepatitis B or C) or cirrhosis (alcoholism being the most common cause of hepatic cirrhosis). In countries where hepatitis is not endemic, most cancers in the liver are not primary HCC but metastasis (spread) of cancer from elsewhere in the body, e.g. the colon. Treatment options of HCC and prognosis are dependent on many factors but especially on tumor size and staging.

ORTHOPEDICS |
|
Orthopedics - The branch of medicine that deals with the prevention or correction of injuries or disorders of the skeletal system and associated muscles, joints, and ligaments. Orthopedic surgery or orthopedics (Commonwealth: "orthopaedics") is the branch of surgery concerned with acute, chronic, traumatic, and recurrent injuries and other disorders of the musculoskeletal system, its muscular and bone parts. Apart from the mechanical considerations, it also is concerned with the pathology, genetics, intrinsic, extrinsic, and biomechanical factors involved.

PRESSURE SORE |
|
Bedsores, also called pressure sores or pressure ulcers, are ulcers (sores) caused by prolonged pressure or rubbing on vulnerable areas of the body, such as bony or cartilaginous areas that are prone to moisture and friction. Decubitus ulcers are pressure ulcers that occur when the patient lies on his or her back for long periods (Wilhelmi and Neumeister, 2005). Examples of areas vulnerable to pressure ulcers include the hips, ankles, heels, elbows, ears, and pressure points on the lower back (near the tail bone, sacrum, or iliac crest). Pressure sores are also caused by prolonged sitting, or certain patterns of sitting behaviour

RADIOLOGY |
|
Radiology is the medical specialty that utilizes and interprets imaging technologies to diagnose disease. Traditionally it was the branch of medical science dealing with the medical use of X-rays emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. Radiologists now also use all other imaging technologies (such as ultrasound, computed tomography (CT) and magnetic resonance imaging) to diagnose or treat disease. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the help of medical imaging.

|
Surgical - Gastroenterology is the study of diseases of the intestinal tract. These diseases include conditions that affect the esophagus, stomach, pancreas, liver, small intestine, and colon.
