Radiation therapy is a targeted treatment which will only work if everything is done correctly before the treatment starts. The Radiation Therapy Diagnosis and Staging phase is like a mapping period. This is where oncologists find out where the tumor is, how big it is and if it has spread. They use this information to create a treatment plan that’s just right for the patient. Liv Hospital is well known for the use of technology, including molecular and digital imaging.
The Role of Diagnosis in Radiation Planning
Diagnosis is the process of finding out if someone has cancer and what type of cancer it is. When it comes to radiation diagnosis is not about knowing if cancer exists. It is also about understanding how the cancer behaves.
Biopsies and Pathology
The first step is often a biopsy. This is where a small sample of tissue is looked at under a microscope. This tells the radiation oncologist if the tumor will respond to radiation or if other treatments, such as chemotherapy or immunotherapy are needed first.
Biomarker Testing
Now diagnosis also includes genomic profiling. This means looking at the mutations in the tumor. The team at CANCER Radiation Therapy Diagnosis and Staging can use this information to predict how fast the cancer will grow. They can then adjust the radiation dosage accordingly.
Understanding Cancer Staging
Cancer staging is a way to describe how bad some-one’s cancer is. It is based on the size of the tumor and if it has spread to other parts of the body. For radiation therapy staging determines if the treatment will try to get rid of the tumor or just relieve the symptoms.
The TNM System
Oncologists use the TNM system to stage cancer:
- T (Tumor): This refers to the size and extent of the tumor.
- N (Node): This refers to the number of lymph nodes that have cancer.
- M (Metastasis): This refers to if the cancer has spread to parts of the body.
You can find information on how these stages affect your treatment at CANCER Radiation Therapy Diagnosis and Staging.
Advanced Imaging: The “Eyes” of the Oncologist
Once we know the stage of the cancer the radiation team needs a map of the patient’s body. This is done using high-resolution imaging.
- CT Simulation: This is the common tool for radiation planning. It creates pictures of the body allowing physicists to calculate how the radiation beams will travel through tissues.
- MRI (Magnetic Resonance Imaging): This is better for looking at tissues. It is often used with CT scans to help doctors see the tumor boundaries and healthy organs.
- PET-CT: This type of imaging finds areas of metabolic activity. This ensures that the radiation is targeted at the active parts of the cancer.
Why Precision Matters?
The goal of radiation therapy at Liv Hospital is to give the tumor the dose of radiation while protecting the healthy organs. Accurate staging makes sure we do not under-treat a cancer that has spread. Precise diagnosis prevents over-treating growing or benign tumors. Going through radiation therapy can be over-whelming. The process of diagnosis and staging is designed to give you the safest and most effective treatment. When a treatment is planned carefully you can focus on live and feel getting better. Taking care of your body and mind during this time is also important. Eating well and reducing stress can help you recover.
