Q:1 Treatment of breast cancer by radiotherapy.
ANSWER : Radiation therapy for breast cancer uses high-energy X-rays, protons or other particles to kill
cancer cells. Rapidly growing cells, such as cancer cells, are more susceptible to the effects of radiation
therapy than are normal cells.
The X-rays or particles are painless and invisible. You are not radioactive after treatment, so it is safe to
be around other people, including children.
Radiation therapy for breast cancer may be delivered through:

External radiation. A machine delivers radiation from outside your body to the breast.
This is the most common type of radiation therapy used for breast cancer.

Internal radiation (brachytherapy). After you have surgery to remove the cancer, your
doctor temporarily places a radiation-delivery device in your breast in the area where the
cancer once was. A radioactive source is placed into the device for short periods of time
over the course of your treatment.
Radiation therapy may be used to treat breast cancer at almost every stage. Radiation therapy is an
effective way to reduce your risk of breast cancer recurring after surgery. In addition, it is commonly
used to ease the symptoms caused by cancer that has spread to other parts of the body (metastatic
breast cancer).
Q : 2 Localizations for which combined radiotherapy is used.
ANSWER : Chemotherapy uses anti-cancer (cytotoxic) drugs to destroy cancer cells. Radiotherapy uses
high-energy rays to destroy cancer cells. The chemotherapy drugs can make cancer cells more sensitive
to radiotherapy. Combining both treatments is often more effective than having either treatment on its
own.
