Proton Therapy
Proton therapy is a type of particle therapy in
which high-energy proton beams are delivered
to tumors by a cyclotron. With proton therapy,
doctorsdeterminetheprecisepointinapatient’s
body where the proton releases the majority of
its energy, maximizing exposure to cancer cells
while minimizing exposure to normal tissue.
Proton therapy is usually delivered in 20-35
treatments with typical outpatient sessions
lasting less than five minutes. Side effects, such
as fatigue, are usually minor and temporary.
Stereotactic Body Radiation Therapy
SBRT is a specialized form of radiation
therapy administered in no more than five
treatments by an advanced radiosurgery
system. During treatment, high doses of
radiation are delivered to tumors with
pinpointprecision.Atypicaltreatmentsession
takes about 15 minutes and does not require
surgery or sedation. Due to the extreme
accuracy of radiation delivery, side effects, if
any, are usually minor and temporary.

About San Diego Radiosurgery
Opened in 2008 through a partnership with Palomar Health, San Diego Radiosurgery
specializes in stereotactic radiosurgery using Novalis Tx® technology. Our center was
one of the first in the country to treat a patient using the Novalis Tx radiosurgery
platform with ExacTrac® adaptive gating. This technology enables doctors to adjust
the size and shape of radiation beams, compensating for patient movement and
minimizing radiation exposure to healthy tissue. San Diego Radiosurgery has extensive
experiencetreatinglungcancerpatients,whichrepresentthemajorityofourcases.
