Question

Which one of the following therapies targets only cancer cells and not the normal body cells?

• A. Immunotherapy
• B. Surgery
• C. Aromatherapy
• D. Chemotherapy

Answer 1

The correct option is A Immunotherapy

Cancer treatment techniques also damage normal body cells. Chemotherapy and Radiation therapy are all generalised because they do not target specific cells which are cancerous. These therapies kill both cancer and non-cancer cells and hence, the patient becomes very weak and also develops many side effects like hair loss and loss of appetite. To overcome these problems, targeted therapies are being used. Immunotherapy is a type of treatment that uses certain parts of a person’s immune system to fight diseases such as cancer. Immunotherapies either stimulate the activities of specific components of the immune system or counteract signals produced by cancer cells that suppress immune responses. The main types of immunotherapy now being used to treat cancer include monoclonal antibodies. These are man-made versions of immune system proteins. Antibodies can be very useful in treating cancer because they can be designed to attack a very specific part of a cancer cell.
