Sorry, no etymologies found.
That could be what Dr. Katz calls "active surveillance with possible delayed intervention" should the cancer start to grow, or for someone like the elderly New Yorker who wanted the cancer out, a relatively new procedure called cryosurgery.
The trial combines a freezing technology called cryosurgery with therapy in which white blood cells known as dendritic cells are multiplied more than 1 millionfold and used to activate the body's defenses, fighting the cancer wherever it has spread.
Cryotherapy is also used as a method of treating localized areas of some cancers (called cryosurgery), such as prostate cancer and to treat abnormal skin cells by dermatologists.
Carnegie Mellon University's Yoed Rabin and Kenji Shimada have received a four-year, $1.3 million grant from the National Cancer Institute to develop computerized training tools for cryosurgery, which is the destruction of undesired tissue, such as cancerous tumors and organs, by freezing.
The first case was a terrible oral tumor that was recovering after receiving cryosurgery -- freezing the tumor to kill it.
An accomplished skier, he got back on his skis not long after the cryosurgery and, five hundred yards down an easy slope, slipped at three miles an hour on a patch of ice and broke his hip—which meant four months on crutches and in a wheelchair to avoid putting weight on the fractured bone.
It begins with slow-growing, pre-cancerous lesions which can be indentified with screening and removed with cryosurgery, the freezing technique used to remove warts, moles and small skin cancers.
Then, cryosurgery is performed in the same visit to destroy the abnormal cells.
She went over the list of treatment options: “cryosurgery, or freezing of the pre-cancerous cells; laser surgery to burn off whatever was left over.”
And just about everywhere, but especially in Asia (see my recent article on the Global Post. com) and increasingly in Latin America, skin whitening -- using surgery, cryosurgery, lasers, whitening "needles" (administered in regimens), bleaches, and skin whitening creams and pills -- is surging.
