Understanding Your Radiation Therapy Process
Radiation therapy is a common and effective treatment for cancer that uses high-energy rays to destroy cancer cells. The primary mechanism involves damaging the DNA within these cells. When radiation hits the DNA, it creates breaks in the DNA, which prevents the cancer cells from growing, dividing, and multiplying. Unlike normal cells, cancer cells have a reduced ability to repair this damage, leading to their eventual death. The treatment is meticulously planned to focus on the cancerous area, minimizing exposure to healthy tissues and reducing side effects. This targeted approach ensures that the maximum dose of radiation is delivered to the tumor while sparing as much of the surrounding normal tissue as possible.
Radiation therapy is a versatile treatment that can be used to treat a wide variety of tumors. Some of the common types of tumors that can be treated with radiation therapy include:
- Head and Neck Cancers: These include cancers of the throat, larynx, tongue, and nasal cavity.
- Breast Cancer: Often treated with radiation therapy after surgery to eliminate any remaining cancer cells.
- Prostate Cancer: Frequently treated with external beam radiation therapy or brachytherapy.
- Cervical Cancer: Radiation therapy is often used in conjunction with chemotherapy.
- Lung Cancer: Radiation therapy can be used alone or in combination with surgery and chemotherapy.
- Brain Tumors: Both primary brain tumors and metastatic brain tumors can be treated with radiation therapy.
- Rectal and Anal Cancers: Treated with radiation therapy, often combined with chemotherapy.
- Lymphomas: Both Hodgkin and non-Hodgkin lymphomas can be treated with radiation therapy.
- Skin Cancer: Certain types of skin cancer can be effectively treated with radiation therapy.
- Pancreatic Cancer: Radiation therapy is sometimes used in combination with other treatments.
These are just a few examples, and many other types of tumors can also be treated with radiation therapy. The specific approach and type of radiation used depend on the location, size, and stage of the tumor, as well as the patient’s overall health and treatment goals.
