Clinical Study using the BSD-2000 Hyperthermia System Combined with Chemotherapy to Treat Pediatric Tumors Shows Promise

SALT LAKE CITY, April 22, 2010— BSD Medical Corporation (“BSD”) (NASDAQ:BSDM) today reported clinical study data showing that hyperthermia, using the BSD-2000 Hyperthermia System, combined with chemotherapy has the potential to improve control rate and long term survival for the treatment of children with high-risk cancer who have a dismal prognosis.

The clinical study data will be presented by Rüdiger Wessalowski, M.D, Associate Professor at the Clinic of Pediatric Hematology and Oncology, Heinrich-Heine University, Dusseldorf, Germany at the annual Society for Thermal Medicine (STM) meeting to be held in Clearwater, Florida on April 23 to April 26, 2010.

The treatment involves cisplatin based chemotherapy combined with deep hyperthermia using the BSD-2000•3D/MR Hyperthermia System. The cancers treated were largely non-cranial germ cell and rhabdomyosarcomas. The study analyzed the ability of the BSD-2000•3D/MR to non-invasively measure the temperature changes during delivery of hyperthermia. The report involved 628 treatments delivered to 115 children (71 with tumor recurrence and 44 with tumors that could not be surgically removed or that had responded poorly to previous therapies).

Dr. Wessalowski stated, “By multimodality therapy with regional hyperthermia, local tumor control rate and long term survival can be improved in children with high-risk tumors with dismal prognosis. Multiple channel heat applicators and non-invasive MR temperature monitoring for childhood cancer can produce precise target volumes with substantial sparing of normal tissues.”

About Heinrich-Heine University, Dusseldorf, Germany
The University Pediatric Oncology Clinic at Dusseldorf has taken the lead on several national and international studies designed to optimize pediatric oncology therapy. For more than 10 years the Dusseldorf Pediatric Oncology Department has pioneered the application of hyperthermia therapy for treating children’s cancers. The treatments use a BSD-2000 Hyperthermia System to deliver deep regional hyperthermia combined with chemotherapy, per a treatment protocol adopted by the German Society for Pediatric Oncology and Hematology.

About BSD Medical Corporation ( www.BSDMedical.com)

BSD Medical Corporation develops, manufactures, markets and services systems to treat cancer and benign diseases using heat therapy delivered using focused radio frequency (RF) and microwave energy. BSD’s product lines include both hyperthermia and ablation treatment systems. BSD’s hyperthermia cancer treatment systems, which have been in use for several years in the United States, Europe and Asia, are used to treat certain tumors with heat (hyperthermia) while increasing the effectiveness of other therapies such as radiation therapy. BSD’s microwave ablation system, which the Company will introduce to the market this year, has been developed as a stand-alone therapy to employ precision-guided microwave energy to ablate (destroy) soft tissue. The Company has extensive intellectual property, multiple products in the market and well established distribution in the United States, Europe and Asia. Certain of the Company’s products have received regulatory approvals in the United States, Europe and China. The BSD-2000 is restricted to investigational use in the US.
