Check Radiation Therapy Safety Questions

Q: What are the uses of radiation for cancer?

A: In addition to actively treating the tumor and its growth with the goal of a long-term cure, radiation therapy can be used to shrink tumors and reduce pressure, pain, and other symptoms of cancer in cases when it is not possible to completely eliminate the disease. This is called palliative radiation therapy, in which the goal is to improve a person's quality of life.

Q: Is it true that radiation cannot be controlled because it's invisible?

A: Although radiation is invisible, FROS radiation oncology team can control it using treatment machines. Doctors have been safely and effectively treating patients with radiation therapy for more than 100 years.

Q: Will radiation therapy cause another cancer?

A: Undergoing radiation therapy slightly increases the risk of developing a second cancer. However, it is important to remember that, for many people, radiation therapy can eliminate the cancer. This benefit far outweighs the risk that the treatment could cause a cancer later in life.

Q: Does radiation therapy harm surrounding organs?

A: The amount of damage done to the surrounding areas of the body depends on the type and location of the radiation. For example, men with prostate cancer who receive radiation therapy to the prostate may experience bowel or bladder problems because these organs are all close to each other. As much as possible, the radiation is aimed precisely at the tumor and the nearby tissues to avoid harming the surrounding organs. Talk with your doctor to learn what parts of your body will be affected by the radiation therapy.

Q: Is radiation therapy painful?

A: You cannot feel radiation from the machine, even during daily treatments.

Q: Do all patients experience the same side effects of radiation therapy?

A: For some people, radiation therapy causes few or no side effects. For others, the side effects are more severe. The reactions often begin by the second or third week of treatment and may last for several weeks after the final radiation treatment. Your radiation therapy health care team will work with you to ease or prevent many of these side effects

Q: Does radiation therapy cause infertility?

A: Radiation therapy to the pelvic region can affect the reproductive system. For some women, permanent infertility (the inability to conceive a child or maintain a pregnancy) can occur, generally only if both ovaries receive radiation. Men receiving radiation therapy to the testes or to nearby organs, such as the prostate, will have lowered sperm counts and reduced sperm activity that affects fertility.

Q: Does radiation treatment make a person lose his or her hair?

A: Radiation therapy is a local treatment, meaning it only affects the area of the body where the tumor is located. People do not lose their hair from having radiation therapy, unless it targets a part of the body that grows hair, such as the scalp.

Q: Should a person having external beam radiation therapy avoid physical contact with friends and family because of possible radioactivity?

A: External-beam radiation therapy does not make a person radioactive at any time. The radiation is delivered to the body, and there is no lingering radiation once the treatment machine is turned off

Q: Will I feel anything after my treatment?

A: Many patients continue with most of their normal activities during treatment — working, golfing, gardening, etc. Depending on the area being treated, however, there may be side effects including fatigue, nausea, "sun-burned" skin, or diarrhea. FROS physicians will discuss the likely side effects and prescribe medication for some conditions.

Q: Will I be able to drive after my radiotherapy treatment?

A: Almost all patients are able to drive while receiving radiotherapy treatment. However, with some types of cancer, driving may NOT be recommended due to fatigue or strong pain medication. Your physician will be able to address your specific case.

Q: Is it true radiation is always used with chemotherapy and/or surgery?

A: Although some types of cancer respond best to combination treatment approaches—which may include radiation plus surgery, chemotherapy, or immunotherapy—radiation therapy alone can be an effective treatment for some cancers.


Q: How can I be sure my treatment plan is the best and safest for me?

A: FROS Radiation Oncology Cyberknife Center has a team of highly trained, board-certified radiation oncologists leading your treatment. They are joined by a team of knowledgeable, board-certified medical physicists. Together, they follow the most thorough safety guidelines in the medical community.

Q: How does the team confirm delivery of the correct dose?

A: The FROS Radiation Oncology Cyberknife Center team performs thorough quality assurance for every single plan and every single patient before treatment. For patients receiving Intensity Modulated Radiation Therapy (IMRT), the team radiates a “phantom” with radiation detectors inside to confirm that the radiation dose delivered is correct. This procedure is done before the first treatment is delivered.

Q: How do you ensure that the radiation is being delivered to the correct area?

A: The radiation oncology team performs daily image guidance for IMRT and other sophisticated treatments to confirm proper position before the patient receives his or her daily treatment.

Q: What does the team do to prevent human error during the treatment?

A: There are always multiple radiation therapists on each machine as an added safety measure. In addition to a morning quality assurance checklists, the FROS Radiation Oncology Cyberknife team has different people checking the same thing to further reduce the chance of human error.

Q: How do you assure that the equipment is functioning properly?

A: In addition to employing full-time board certified medical physicists performing daily, monthly, semi-annual and annual Quality Assurance tests, FROS has service contracts with expert engineers for the radiation equipment we use. These experts work diligently to establish and validate the functions of the equipment.

International Patients Family who received Cyberknife Treatment for Brain Cancer 

Dr. Yeung,

I am very much thankful for you sending me pictures of my mom with Dr. Yeung.  I salute to you people and the country whose medical science is so ahead from the rest of the world.  I am thankful of you all for giving a new life (rebirth) for my mom.  I am also glad that she is doing great after her Cyberknife treatment, her health is improving day by day.  I am also following you all on facebook.

God bless.

Thanking you,

Pranav Khakhar


Local Cyberknife Prostate Cancer Patient

"My regular doctors didn't know alot about Cyberknife.  My inspiring wife found Cyberknife and told me about it.  We believe you have to do your homework.  It is your responsibility for your health.  It was obvious to me to go with a treatment for prostate cancer I could complete in five days, versus two months of radiation.
