Strahlentherapie vs Chemotherapie
chemotherapy
'Chemotherapie' and 'Strahlentherapie' are both treatments that are often used for cancer. That is why they are easy to confuse. The important difference is the type of treatment: in chemotherapy, medications or chemical substances act inside the body against diseased cells. In radiation therapy, a specific area of the body is treated with radiation. In conversations about cancer treatment, you should pay close attention to this difference because they are two different methods.
Strahlentherapie
Bei der Strahlentherapie wird nur die betroffene Stelle am Rücken behandelt.
In radiation therapy, only the affected spot on the back is treated.
Chemotherapie
Während der Chemotherapie bekommt sie regelmäßig Medikamente in der Klinik.
During chemotherapy, she regularly receives medication at the clinic.
