Scientists have confirmed that many people with early-stage breast cancer may only need five days of radiotherapy after surgery instead of the traditional three-week treatment plan. The findings come from a major clinical trial that followed patients for an entire decade and found that the shorter treatment was just as safe and effective as the […] The post Major breast cancer study shows patient…

Cancer Therapy & Oncology  - Juniper Publishers Abstract Cancer can become anywhere in the human body almost including trillions of cells. Cancerous tumors spread or invade into the tissues to form new tumors that named as the process of metastasis. Radiation therapy (RT) was first used to treat cancer over a hundred years ago. The progress has been made to improve the effectiveness of this …

Patients with bone cancer are often treated with alpha particle radiation therapy, delivered into or very close to the tumor. However, it is unknown whether the radioactive elements spread throughout the surrounding area or to the body’s vital organs, where they could cause toxic effects. Researchers developed a computational framework to measure the concentration of [..] The post SPECT Imaging I…

Respiratory motion can influence the efficacy and safety of radiation therapy in the thorax and abdomen. Free-breathing 4D-MRI is a promising alternative to 4D-CT for motion management in MRI-guided linac treatments, providing excellent soft-tissue contrast with no ionizing radiation. High-quality MR images free of motion artifacts can distinguish lesions from normal tissue. MRI techniques, howev…
