Proton therapy for breast cancer

High doses of radiation in a highly complex area to treat breast cancer

Proton therapy is a treatment whose application in breast cancer is under development, although some studies suggest that it is a highly efficient alternative for patients with types of breast cancer that have an indication for radiotherapy. 

Many breast tumours are treated in combination with other therapies, such as surgery, chemotherapy, hormone therapy, external and intraoperative radiotherapy. The main advantage of proton therapy is that it reduces the amount of irradiation of the surrounding healthy tissues and avoids undesirable effects on critical organs nearby the breast, such as the skin, heart and lungs, as well as avoiding short and long-term effects on the lymphatic vessels.

The Breast Cancer Area of the Clinic counts on highly qualified specialists in oncoplastic surgery techniques and breast reconstruction, in the administration of the latest therapies, such as immunotherapy, and innovative treatments aimed at improving the patient's quality of life.

Indications for proton therapy in breast cancer

  • Inflammatory breast cancer.
  • Recurrent breast cancer.
  • Triple negative breast cancer.
  • Ductal carcinoma in situ.
  • Invasive ductal carcinoma.
  • Invasive lobular carcinoma

In selected cases of recurrent breast tumours, proton therapy is a treatment of choice for those patients who have already received conventional radiotherapy in the area that is close to the reappearance of the tumour.

Proton therapy allows for more customised dosimetric distributions in patients with breast reconstruction after mastectomy.

Main advantages of proton therapy in breast tumours

La radioterapia más avanzada y precisa, especialmente efectiva en el cáncer de mama por su localización, rodeada de estructuras vitales.

Less toxicity

Minimizes damage to healthy tissue and adverse effects on the surrounding critical organs (heart and lung) and lymphatic vessels. In addition, it ensures a lower risk of short and long-term radio-induced complications, such as secondary tumours.

Higher precision

In certain cases, for those patients who were previously treated with radiotherapy in the thoracic cage (lungs, lymphoma or other breast cancers), proton therapy becomes an effective treatment of choice due to its ability to avoide damage to the surrounding healthy tissue.

Greater control

In patients with tumours in the left breast, proton therapy drastically reduces the exposure of the heart and the coronary vessels. It is an ideal treatment for patients who also suffer from heart problems.

The technology of the Clinic

  • Multi energy system: It changes the energy very quickly for the sweeping of the next treatment layer.
  • Pencil beam scanning: This is the most advanced version of proton therapy administration and is especially interesting in breast cancer. Its advantage is the capacity to enclose the tumour in a half circle, adjusting the dose and reducing the involvement of healthy tissue and, therefore, the risk of damaging surrounding vital organs.
  • Cone-beam tomography: in a 360º gantry, the integrated CT allows the exact verification of the condition of the tumour on the very day of the treatment.
