Although electrical devices that create a heated probe may be used for the cauterization of tissue in some applications, electrosurgery refers to a different method than electrocautery. Electrocautery uses heat conduction from a probe heated to a high temperature by a direct electrical current (much in the manner of a soldering iron). This may ...
Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding. This technique induces localized tissue burning and damage, the zone of which is controlled by the frequency and power of the device.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
The consequences of overdiagnosis and overtreatment resulting from cancer screening can lead to a decline in quality of life, due to the adverse effects of unnecessary medication and hospitalization. [10] [12] [13] The accuracy of a cancer screening test relies on its sensitivity, and low sensitivity screening tests can overlook cancers. [10]
Several types of screening exist: universal screening involves screening of all individuals in a certain category (for example, all children of a certain age). Case finding involves screening a smaller group of people based on the presence of risk factors (for example, because a family member has been diagnosed with a hereditary disease).
Surgery [a] is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars ...
Oncology is a branch of medicine that deals with the study, treatment, diagnosis, and prevention of cancer.A medical professional who practices oncology is an oncologist. [1]
The 2021 U.S. Preventive Services Task Force guidelines recommend annual screening for lung cancer with low-dose computed tomography in adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. [6]
