Chemotherapy is a treatment in which one or more anti-tumorous drugs are combined and administered to destroy tumorous cells and reduce the disease, by using a wide variety of drugs.
Some tumours, mainly, breast and prostate cancer have receptors in the tumorous cells which make them ´sensitive´ to certain hormones, stimulating growth.
The immune system is fundamental in the development and control of tumours. Immunotherapy repairs or increases the response of the patient´s immune system.
Biological therapy treatments use specially designed drugs to block specific aspects of the tumour´s biological make-up.
