Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries. Fibrotic tissue may predispose the tissue to ulceration . Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
Melanoma is a type of skin cancer that is often caused by exposure to ultraviolet light, which can be found in sunlight as well as tanning lamps and beds, according to Mayo Clinic.Skin on the arms ...
Over a 45-year span — between 1975 and 2020 — improvements in cancer screenings and prevention strategies have reduced deaths from five common cancers more than any advances in treatments.
The gel prevents air bubbles from forming between the probe and the patient's skin, and so helps the conduction of the sound waves from the transducer into the body. The watery medium also helps conduct the sound waves. Liquids, including blood, have a low impedance, which means that little energy will be reflected and no visualization possible.
Proton beam therapy has been shown to be just as effective as traditional chemotherapy, with fewer side effects and less treatment time.
