**Radiotherapy: A Comprehensive Guide to Cancer Treatment Using Targeted Radiation**
Radiotherapy is a widely used medical treatment that utilizes high-energy radiation to destroy or damage cancer cells. It is one of the most effective methods in oncology and plays a crucial role in both curative and palliative cancer care. By targeting abnormal cells while minimizing harm to surrounding healthy tissues, radiotherapy helps control tumor growth, reduce symptoms, and improve patient outcomes.
### What is Radiotherapy?
Radiotherapy, also known as radiation therapy, involves the use of controlled doses of radiation to treat cancer and some non-cancerous conditions. The radiation works by damaging the DNA of cancer cells, preventing them from multiplying and eventually causing them to die. Since cancer cells divide more rapidly than normal cells, they are more sensitive to radiation.
