It is a radiotherapywith heavy particles (carbon ions).
Radioactive rays heavier than electrons are called particle rays, and those heavier than helium ions are called heavy particle rays. Heavy particle radiotherapy is a radiotherapy utilizing this heavy particle rays (carbon ions).
Surgery is performed as a treatment in early to intermediate stage cancers. Surgery has great radical curativeness (complete cure) because it directly extracts the cancer focus. However, surgery removes a part of the body, and it therefore changes the shape of the body site and may lower its function.
Heavy particle radiotherapy that treats with radiation from outside of the body to the disease site can be considered treatment without dissection. It has advantages of less pain and body burden due to surgical knives, and fewer side effects than conventional radiotherapy as well.
Heavy particle radiotherapy allows radiation according to the shape and position (depth) of the cancer focus reducing impacts on other normal organs.
Consultation about heavy particle radiotherapy are available in only limited medical institutes. Staff with special knowledge who can answer the details of heavy particle radiotherapy are not necessarily available in many institutes either.
Different institutes have different indications of the therapy. Therefore, Heavy Particle Radiotherapy Clinic, a consultation clinic specialized in heavy particle radiotherapy, offers determination on whether the therapy is indicated or not (second opinion).。
We meet patients’ need to consult with specialized staff and have a second opinion”
The following measures are available
As of September 2021, there are seven heavy particle radiotherapy institutes in Japan.
In all institutes, indications of the therapy has a certain condition and not all cancers are indicated. Indicated diseases differ by condition of disease and the patient
