Cancer treatments combine toxic drugs with X-ray radiation to poison and kill rogue cells and tumors, a treatment standard established for decades. However, a more powerful and accurate radiation source, proton beams, blasts away cancer but has remained out of reach to most doctors… Funding for the new centers comes from a variety of sources. It's better if it's a gift," said Steven Schild, chair of the Department of Radiation Oncology at Mayo Clinic in Arizona. Mayo Clinic received a combined gift of $100 million in seed funds from Robert O. Jacobson, a philanthropist from Iowa. It is building two proton beam therapy centers. The gift will pay for about a third of the two new centers.
