Radiation treatment, also known as radiation therapy, is a common method used to treat cancer by targeting and destroying cancer cells with high-energy rays. It damages the DNA inside these cells, preventing them from growing and dividing. Radiation therapy can be delivered externally, using a machine called a linear accelerator, or internally, through a process known as brachytherapy, where radioactive sources are placed inside the body near the cancer.

This type of treatment is versatile and can be used alone or in combination with other cancer treatments like surgery, chemotherapy, or immunotherapy. Radiation therapy aims to destroy cancer cells while minimizing damage to surrounding healthy tissues. Modern techniques, such as intensity-modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS), allow for precise targeting of tumors, reducing side effects and improving outcomes.

Radiation treatment is typically an outpatient procedure, meaning patients can receive it without the need for hospital stays. The duration and frequency of treatment depend on the type and stage of cancer, as well as the individual patient’s needs. If you have questions about whether radiation therapy is right for you, consult with an expert like Dr. Palas De, the best radiation oncologist in Kolkata.
