Frequent Answers and Qestions

We know patients will have worrisome thoughts after cancer is diagnosed and tend to have a lot of questions. Making a decision about which cancer care to choose depends on personal circumstances and the conditions of the cancers. No cancer is the same and options need to be carefully considered as every approach affects patients differently.

We provide answers to the most common questions about our Proton Therapy. For further questions do not hesitate to contact us.

Q: How many days will it take for treatment to complete?

A: The treatment period will be decided by the pathology of the tissue, location, and progression of the cancer. With daily treatment, lung cancer will take about 2 weeks up to 8 weeks, with an additional week for preparation. Prostate cancer treatment will take 6 to 8 weeks. A patient will be in the treatment center for approximately 30 minutes per day. The actual irradiation time will be only 1 to 2 minutes.

Q: Is the proton therapy painful?

A: Proton therapy is a non-invasive treatment with little or almost no side effects. This basically means you won't feel any pain during the treatment, but some patients may suffer from a skin rash after irradiation.

Q: In traditional radiotherapy, there are adverse effects such as loss of hair and appetite, or emesis. So are there any adverse effects or after effects with proton therapy, too?

A: Proton therapy has significantly reduced adverse effects compared to traditional radiotherapy.

Q: I am receiving radiotherapy now, but is it possible to receive proton therapy if the cancer recurs during radiotherapy?

A: In general, we cannot provide proton therapy at the same location because the accumulated doses would be too large. However, if a new cancer appears near the location of the original tumor proton therapy could be applicable.

Q: If the cancer recurs, can it be treated again?

A: Cancers may recur. If it is appropriate, we can provide treatment. Please contact us in this case immediately so that we can discuss possibilities of using proton therapy.

Q: At what stage of cancer can I receive proton therapy?

A: There are different stages for cancer depending on whether it has metastasized, its size, how much it affects the cells around it, and types and site of the cancer. Under international standards, cancers which are confined to a specific area and which have not metastasized are classified as being at stages I or II. The basic criteria for applying proton therapy is that the cancer should be at one of these stages. However, even if a cancer metastasizes and if it is considered to improve the patients' quality of life or restrain the progression by treating primary or metastatic lesions, proton therapy could be one of the selections.

Q: Is proton therapy a new type of therapy?

A: Proton therapy is has been used by quite a few of medical facilities since 1990, and as of 2013 more than 100,000 patients have been treated world wide.
