Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Nanotechnology in thermal ablation and immunotherapy Currently nanotechnologies has been continuously developed for cancer immunotherapy for their versatility in integration of therapeutic and diagnostic (or termed 'theranostic') multimodalities.
An early clinical trial examines MRI guided ablation to destroy early stage breast cancer tumors. People still need to undergo chemotherapy, radiation. Mom receives new procedure to remove breast ...
Thermal ablation is widely used in biomedical science as a form of heat therapy for cancer. Extreme heat are applied to tumors, damaging the tissues to eliminate the tumors from eligible patients. [2] Similarly, cryoablation can also be used as a potential treatment.
A direct method of accessing and destroying tumour cells can be accomplished by photothermal cancer therapy or photodynamic therapy (PDT). This procedure is known to treat small tumours that are difficult to access and avoids the drawbacks (adverse effects) of conventional methods, including the unnecessary destruction of healthy tissues.

Halas told CNN. After many suggestions, cancer therapy came out of ongoing collaborations with bioengineers looking for different types of biomedical applications. [3] "One of our visions", Halas stated, "no less than single visit diagnosis and treatment of cancer". [4] In 2003 Halas was awarded for Best Discovery of 2003 by Nanotechnology Now. [4]
Conditional ablation in MMTV-PyMT breast cancer cells has been done to reveal pro-metastatic actions of the angiogenic factors, Vascular endothelial growth factor A (VEGF-A). [50] The role of autocrine transforming growth factor beta 1(TGF-β1) signaling on motility and survival in PymT cells derived from an MMTV-PymT mouse mammary cancer. [51]
