Oncothermia – Modulated electro-hyperthermia. Nutritional support and complementary treatments, integrated on a personalised basis alongside conventional cancer treatment.
Modulated electro-hyperthermia therapy, also known as Oncothermia, is a form of local hyperthermia whose principles are based on the application of heat by means of low-frequency waves, with the aim of selectively raising the temperature of tumour tissue. It can produce chemosensitisation and radiosensitisation mechanisms, and may improve the efficacy and benefit of conventional chemotherapy and radiotherapy treatments.
Every patient and every oncological process is different. For this reason, in addition to assessing the possible indication for Oncothermia, we take an individualised approach to aspects such as nutritional status, diet, lifestyle and the need for physical, psycho-emotional and energetic support. Our aim is to accompany patients throughout their oncological process with complementary interventions that can be integrated responsibly with the treatments prescribed by their oncology team.
Medical follow-up makes it possible to assess tolerance, clinical progress and the suitability of the complementary interventions, making any necessary adjustments at each stage of the process.

Hyperthermia has been studied as a complementary treatment in different types of cancer, particularly in combination with radiotherapy and other cancer treatments. The available evidence varies according to tumour type, hyperthermia modality and clinical situation.
Modulated electro-hyperthermia (mEHT) has numerous published clinical studies, although the level of evidence is not equivalent for all indications. For this reason, we assess each case individually.

Medical direction
Dr Jorge Pérez-Calvo Soler is a physician specialised in the field of integrative medicine, with more than four decades of professional experience devoted to the study and clinical application of different approaches related to nutrition, traditional medicine and complementary therapies. Throughout his career he has focused his activity particularly on Nutrition and Dietetics, Traditional Chinese Medicine, Acupuncture and Clinical Environmental Medicine, integrating this knowledge with his medical training and with a global vision of health and of the person.
He holds a degree in Medicine and Surgery from the Universitat Autònoma de Barcelona (UAB), where he trained at the Vall d'Hebron University Hospital. He subsequently broadened his training in the physiology of nutrition and in different disciplines related to integrative medicine, including a Doctorate course in Nutrition at the Universitat Autònoma de Barcelona (UAB), carried out under the direction of Dr Ramón Segura, Professor of Biochemistry.
In 2009 he obtained accreditation in Naturopathic Medicine from the Col·legi Oficial de Metges de Barcelona (COMB — Barcelona Official Medical Association), an institution where his accreditation in Acupuncture has also been registered since 2005. His academic training also includes a Master's degree in Traditional Chinese Medicine (TCM) and Acupuncture from the University of Witten/Herdecke, completed between 2001 and 2005, and a Master's degree in Clinical Environmental Medicine from the European Academy for Environmental Medicine (EUROPAEM) and the Associazione Italiana di Medicina Ambiente e Salute (ASSIMAS), completed between 2014 and 2015.
Throughout his clinical career, Dr Pérez-Calvo Soler has developed a model of care based on an integral vision of the person, paying particular attention to factors such as diet, nutritional status, lifestyle and other aspects related to wellbeing and health.
He is the director of the Centre for Biological Medicine and Oncothermia in Barcelona, where he carries out his activity in the field of integrative medicine and the complementary accompaniment of patients.
His approach contemplates the integration of different therapeutic and support resources, adapted to the characteristics and needs of each person. In this context, integrative interventions are proposed as complementary to conventional medical care, without replacing the treatments indicated by the specialists responsible for each patient.
He has developed an extensive teaching activity, particularly linked to nutrition, dietary therapy and integrative medicine. Since 1985 he has taught courses and seminars on Nutrition and Energetic Dietary Therapy for Master's programmes in Personal Growth and Naturopathic Medicine at the Universitat Ramon Llull and at the Fundació Bosch i Gimpera of the Universitat de Barcelona, in addition to taking part in courses and seminars in different European and Latin American countries, among them the Netherlands, Switzerland, Germany, Portugal, Israel, Peru, Colombia and Belgium.
In 1988 he obtained accreditation as an "Assistant Teacher & Dietary Counsellor" from the Kushi Foundation, linked to his specialisation in nutrition and dietary therapy, and he subsequently worked as an associate teacher of the Kushi Foundation Network.
His teaching and public engagement have also extended to the field of integrative oncology. In 2019 he took part as a speaker in the 12th European Congress for Integrative Medicine (ECIM), held in Barcelona, with a presentation devoted to dietary therapy and the role of nutrition as an adjuvant treatment for cancer patients. In 2025, he was a speaker at the 7th International Congress on Integrative Medicine (ICIM) in Porto, Portugal, with the lecture "Integrative Medicine in Cancer Care in Europe: From Clinical Necessity to Evidence-Based Therapeutical Possibilities".
In 2024, he was the coordinator of the workshop on the use of medical ozone therapy within the framework of complementary medicine, held at the European Parliament in Brussels on 14 February 2024 under the title "New Horizons for Healthcare in Europe: Medical Ozone Therapy and Its Many Benefits".
In 2021 he also took part as coordinator and speaker in a workshop organised by the European Parliament within the framework of ENVI (Committee on the Environment, Public Health and Food Safety), which addressed integrative medicine and oncology and the role of complementary medicine in prevention and in the support of cancer patients.
His teaching and public engagement are complemented by the publication of the books Nutrición energética y salud. Bases para una alimentación con sentido (Grijalbo / DeBolsillo), ¡Revitalízate! Las mejores recetas de la cocina energética (RBA Integral), Nutrición energética para la salud del sistema digestivo (Editorial Edaf / Plus Vitae), Nutrición energética para la salud del hígado y la vesícula (Editorial Edaf / Plus Vitae), Alimentos que curan. Nutrición energética para tu cuerpo, mente y emociones (with Pilar Benítez, Ediciones Oniro/Booket, Grupo Planeta) and Comer, sentir… ¡vivir! (Grijalbo / Penguin Random House). He is also co-author of chapter 32, "Alimentación y terapia nutricional coadyuvante al tratamiento del cáncer" ("Nutrition and adjuvant nutritional therapy in cancer treatment"), of the book Oncología Integrativa. Manual Básico y Clínico (Editorial Médica Panamericana).
He is a member of different professional societies and associations linked to integrative medicine, naturopathic medicine, acupuncture and TCM and other areas of complementary therapies, among them the Spanish Society of Health and Integrative Medicine (SESMI), the Spanish Association of Integrative Physicians (AESMI), the Spanish Association of Naturopathic Physicians (AEMN), the American College for Advancement in Medicine (ACAM), the Spanish Society of Ozone Therapy (SEOT), the Spanish Association of Medical Professionals in Ozone Therapy (AEPROMO) and the International Lyme and Associated Diseases Society (ILADS).
Dr Pérez-Calvo Soler's career is characterised by the combination of his medical training with the continued study of different disciplines related to nutrition and integrative medicine. His clinical and teaching experience has led him to develop a vision in which diet, lifestyle and certain complementary therapies can form part of the accompaniment of patients, always from an individualised perspective and within the framework of responsible medical care.
His professional activity thus focuses on integrating different areas of knowledge in order to offer a global approach to the person, taking into account both their clinical needs and those factors related to nutrition, environment and wellbeing that may form part of their health process.
