Cancerology is the branch of medicine concerned with the study, diagnosis and treatment of cancerous diseases.

The aim is to identify the mechanisms of tumour formation (carcinoma, sarcoma, lymphoma, myeloma, leukaemia, mesothelioma, melanoma, glioma, metastases, etc.) and to continuously improve and develop the state of knowledge in order to develop the best possible therapy for each individual case.

Cancer centres

For over a decade, Swiss Oncology Network has set its sights on one overriding goal: to offer everyone living with cancer privileged access to treatments and the best and safest treatment strategies for their specific illness.

Cancer in Switzerland

Every year, cancer affects over 44,000 people in Switzerland (approx. 20,000 women and 24,000 men). Due to demographic reasons (an ageing population), the number of new diagnoses is still on the rise, but thanks to various screening programmes and ongoing advances in diagnosis and therapy, chances of survival continue to increase.

Types of tumours

Cancer cells

Cancer cells are so-called ‘immortal’ cells because they multiply without dying, accumulating to form a tumour. As they do not function like a normal cell, they divert ‘local resources’ to feed on them (neoangiogenesis), blocking and attacking the body’s immune defences.

Benign tumour

A localised mass consisting of cells that retain their function; this mass does not alter the surrounding tissues (e.g. wart, mole), but if it presses on an organ, it must be removed.

Malignant tumour (cancer)

A mass of cancerous cells that can invade and destroy healthy neighbouring tissues and migrate to other parts of the body to form metastasis. A distinction is made between solid tumours and cancers of blood cells (haematologic malignancies)


Tumours are formed on tissues that cover an external (skin, mucous membranes) or internal (digestive tract, glands) surface of the body (breast cancer, prostate cancer, skin cancer, bowel cancer, lung cancer)


A distinction is made between soft tissue sarcoma and bone sarcoma (osteosarcoma): Soft tissue sarcoma develops in the connective or supporting tissues (adipose, fibrous, blood and synovial tissues; muscles, lymph vessels and peripheral nerves) and is relatively rare in adults. Osteosarcoma, or bone sarcoma, is mainly formed on long bones (femur, tibia) or flat bones (ribs, sternum).


A malignant tumour that develops in the lymph nodes and vessels (the body’s immune system); a distinction is made between Hodgkin lymphoma (a rare disease that affects certain types of lymphocytes) and non-Hodgkin lymphoma.


Cancer of plasma cells (white blood cells in the bone marrow), which can affect the bones, immune system, kidneys and red blood cells in the blood.


Blood and bone marrow cancer affects the production of blood cells (white blood cells).


Tumour of the tissue surrounding the lungs (pleura), the abdominal cavity (peritoneum) or the heart (pericardium).

Melanoma – skin cancer

Tumour that develops from skin cells, melanocytes.


Brain tumour which can develop in the brain and other parts of the nervous system (brain stem, spine).


Tumours formed by cancer cells that have broken away from the ‘primary tumour’ (first tumour) and which – via the lymph or blood vessels – have migrated to another part of the body (lung, bone, brain, liver).

Risk factors

It is now known that many cancers are caused by a genetic component. But there are also many external risk factors, resulting from environmental factors or individual lifestyles. These include:

  • Ageing
  • Unbalanced diet
  • Being overweight
  • Smoking
  • Excessive alcohol consumption
  • Sedentary lifestyle
  • Lack of physical activity
  • Pollutants and other harmful substances
  • UV rays
  • Hereditary or genetic factors

Cancer treatment

The objectives are:

- Remove the tumour (tumour tissue), enabling long-term recovery
- Reduce tumour size to minimise any complications, organ compression, invasion of healthy tissue, etc.
- Prevent recurrence
- Avoid or manage the formation of metastasis
- Relieve pain and any other symptoms

There are currently three main areas of treatment – oncological surgery, systemic treatment, also known as «medical oncology» and radiotherapy/radiation oncology – which are often combined in the therapeutic approach offered to the patient for the best possible chance of finding a cure.

Treatment pathway

The treatment pathways at our centres offer patients and their loved ones the best possible conditions to cope with a cancer diagnosis and its treatment.


A clinical examination, suspect image or abnormal biological result may require a patient to consult a specialist who, if necessary, will perform additional examinations to either reject or confirm a cancer diagnosis.

A multidisciplinary conference (Tumour Board), brings together all the specialists involved in the oncology treatment pathway, these are radiology, pathology,nuclear medicine,surgical oncology, medical oncology,radiotherapy, plastic and reconstructive surgery, etc., each specific case is examined in detail and the best possible treatment strategy is discussed and established.


The proposed treatment will be based on the latest national and international clinical practice recommendations, developed by specialists in the field and taking account of each patient’s individual condition, physical and mental resources, environment, needs and wishes.

Supportive care

In order to better manage the impact of the disease or the adverse effects of treatments, patients may be offered supportive care or – in a more structured form – outpatient cancer rehabilitation programmes.


As soon as the diagnosis is given, the medical and paramedical team is on hand to answer any questions or concerns that the patient or their loved ones may have. This support covers physical, psychological, social, family and professional areas, among others, ensuring patients are as well-equipped as possible when planning their treatment pathway.
