A tumor marker is a biomarker that can be used to indicate the presence of cancer or the behavior of cancers (measure progression or response to therapy). They can be found in bodily fluids or tissue. Markers can help with assessing prognosis, surveilling patients after surgical removal of tumors, and even predicting drug-response and monitor ...
Injector pens remove some of the complications of syringes by allowing the pen to be "pushed" against the skin at a 90-degree angle (removing the need to inject at a proper angle as is the case with syringes), as well as by replacing a long, thin plunger of a syringe with a simple button which is depressed and held to inject the dose.
Geriatric oncology is a branch of medicine that is concerned with the diagnosis and treatment of cancer in the elderly, usually defined as aged 65 and older. This fairly young but increasingly important subspecialty incorporates the special needs of the elderly into the treatment of cancer .
A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule." [18] In cancer research and medicine, biomarkers are used in three primary ways: [19] To help diagnose conditions, as in the case of identifying early stage cancers (diagnostic)
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
Giving clean syringes to people who inject drugs has been found to curb the spread of disease. But syringe programs are being banned in many California communities. The state is fighting back.
Some health care workers prefer to use a syringe-needle technique for venipuncture. Sarstedt manufactures a blood-drawing system (S-Monovette) that uses this principle. [23] This method can be preferred on the elderly, those with cancer, severe burns, obesity, or where the veins are unreliable or fragile.
Dr. Herbert Kleber, a professor of psychiatry at Columbia University and director of the New York State Psychiatric Institute’s Division on Substance Abuse, argues that the robust black market is a sign that the benefit of the medication outweighs the risk. “There is no medication without risk. People die every year from aspirin.
