Cancer Is Fought With Radiotherapy, A Powerful Tool

Before starting Radiotherapy, the patient will undergo a simulation session to determine the exact location and size of the tumor. This involves taking CT scans and/or MRI scans of the patient. The scans are used to create a treatment plan, which determines the dose and schedule of the radiation therapy.

There are several types of external radiation therapy, including:

3D conformal radiation therapy (3D-CRT): This type of Radiotherapy uses a computer to create a 3D image of the tumor and surrounding tissue. The radiation beams are shaped to match the shape of the tumor, which helps to minimize damage to nearby normal tissue.
Intensity-modulated radiation therapy (IMRT): This type of radiation therapy uses a computer to control the intensity of the radiation beams. The intensity can be adjusted to deliver a high dose of radiation to the tumor while minimizing damage to nearby normal tissue.
Stereotactic radiosurgery (SRS): This type of radiation therapy delivers a high dose of radiation to a small area of the brain. It is often used to treat brain tumors that are difficult to reach with surgery.
Stereotactic body radiation therapy (SBRT): This type of radiation therapy delivers a high dose of radiation to a small area of the body. It is often used to treat tumors in the lung, liver, or spine.
