This article provides an overview of various radiation therapy options for cancer treatment, including external and internal methods. It emphasizes personalized treatment planning based on tumor characteristics and patient health. Understanding these options helps patients make informed decisions about their cancer care and manage potential side effects effectively.
Radiation therapy, or radiotherapy, is a widely used method in cancer care that employs high-energy rays to shrink tumors or destroy cancer cells. It can also be used for imaging purposes, such as diagnosing bone fractures, dental issues, blood disorders, or thyroid conditions. This article explores the main types of radiation therapies available today.
Primary Types of Radiation Therapy
External Beam Radiation
This targeted method involves directing high-energy radiation from machines outside the body precisely at the tumor. It uses particles like protons, electrons, and photons. For instance, lung cancer treatments focus the beam solely on the chest, minimizing damage to surrounding tissues. Techniques include 3D conformal, image-guided (IGRT), stereotactic radiosurgery, tomotherapy, IMRT, and stereotactic body radiation therapy.
Internal Radiation
In internal radiation, the radioactive material is placed inside the patient's body. Liquid sources, suitable for thyroid and prostate cancers, are systemic, while solid sources used in brachytherapy are implanted directly into tissues for cancers affecting the neck, breast, head, prostate, eye, and cervix.
Choosing the Appropriate Treatment
Medical professionals select the best radiation therapy based on:
Tumor size
Cancer type and location
Distance from healthy tissues
Patient's overall health and medical background
Other health conditions and age
Always follow your healthcare provider’s advice, as radiation therapy may cause side effects. Consult your doctor before starting treatment.
