The difference between conventional X-ray therapy and proton therapy – and why we are re-examining the way we treat left-side breast cancer.
The majority of breast cancer patients today are able to preserve their breasts as they undergo a lumpectomy followed by post-operative radiation. However, research shows that left-side breast cancer patients treated with radiation have an increased risk of radiation-induced heart problems.
Here, Dr. Brian Chon writes about the connection between X-ray therapy and heart disease and how proton therapy is being used as a cardiac-sparing cancer therapy.

We asked Dr D.G. Vijay, Breast Cancer Specialist for his opinion and this is what he shared
Although, this is a very progressive and sophisticated therapy option for left-sided breast cancer, there are key points that should be considered:
1. Firstly, the machine and training for the same is prohibitively expensive.
2. Data over 20 years is limited as it’s a very new product. The equipment and software has also changed dramatically in the last 10 years. The current generation of machines are capable of complex radiotherapy contouring and dosimetry.
3. It may be more useful for re-radiation in patients with relapse or unrelenting tumors.
4. In India, the need for IMRT machines is greater.
5. Even in USA, some institutions are not in favor of Proton Beam Therapy.
