Cryotherapy is an alternate tumor treatment approach that is typically used when traditional surgery to remove the tumor is ineffective. Cryotherapy can also be used to treat skin conditions, anti-aging, muscle discomfort and rehabilitation, and muscle-related injuries. Cryotherapies are roughly divided into two types: localized/surgical cryotherapy, often known as cryosurgery, and whole-body cryotherapy. Cryosurgery is used to treat skin problems, cancer, and discomfort. Whole-body cryotherapy (WBC) has applications in health and fitness and is commonly used by sportsmen and movie stars. Some of the more unconventional procedures used in WBC include a liquid nitrogen-cooled sauna or a cryotherapy chamber (exposed to fresh oxygenated chilled air). Cryotherapy chambers are commonly used at cryotherapy centers or at home facilities. For significant cryotherapy treatments, cryo-guns, cryoprobes, and gas cylinders are primarily employed in hospitals and clinics.
Cancer is the world's second-biggest cause of mortality, according to the World Health Organization (WHO). In 2012, around 14 million new instances of cancer were identified, with approximately 8.8 million deaths related to it in 2015. According to the World Cancer Research Fund (WCRF) International, 1.1 million new instances of prostate cancer were detected in 2012, with 88 percent occurring in industrialized nations such as France, Australia, the United States, New Zealand, and Switzerland. Cancer treatment options now include surgery, radiation, and chemotherapy. The increased need for non-invasive and focused medicines has resulted in the development of nanotechnology.
