The goal of this clinical trial is to compare whether the use of videoconferencing in breast cancer patients undergoing radiotherapy is better for pre-treatment education than telephone calls. The main question it aims to answer is in breast cancer patient receiving radiotherapy, does videoconferencing, compared to telephone calls for pre-treatment education result in decreased procedural fears and concerns? The investigators hypothesize that the use of videoconferencing for pre-treatment radiotherapy education will decrease breast cancer patients' procedural fears and concerns. Researchers will compare the current standard of care in a 30 minute radiation therapist led pre-treatment education call to the intervention of a 45 minute radiation therapist led videoconferencing call to see if the intervention reduces patient procedural fears and concerns, anxiety levels, and has higher patient satisfaction. Participants will be asked to complete questionnaires at three time points: 1. Baseline - at time of study consent. 2. CT-Simulation - after their radiotherapy CT-Simulation appointment. 3. Day 1 Treatment - after their first day of radiotherapy treatment.

Patients with metastatic non small cell lung cancer with high risk location or size are treated with prophylactic radiation therapy in conjunction with standard of care systemic therapy.

Phase 1-2 study, comparing ultra-hypofractionnated (UH) to a moderately hypofractionnated (MH) radiation therapy, with image guided HDR prostate brachytherapy. Using iso-equivalent doses, a non-inferiority analysis will be done in order to prove UH non-inferior to MH, toxicity wise. Acceptability, tolerability, acute and late toxicity will be reported. MRI visible dominant intra-prostatic lesion will be outlines and variability between radiation oncologists and radiologists will be reported. As secondary objective, biochemical and clinical failure free survival will be reported at 5 \& 10 years.

The primary objective of this study is to determine in women with node negative BC ≤3cm in size, if PBI compared to WBI, both given once-a-day over 1 week following BCS, is non-inferior for LR and reduces adverse cosmesis. The primary outcomes are LR and patient-assessed cosmesis at 3 years post randomization.

This is a phase 1 study to determine the feasibility and utility of using serial magnetic resonance imaging (MRI) to assess treatment response during and after radiation therapy (standard of care cancer treatment) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include three MRI scans (one before, one during, and one after standard of care cancer radiation therapy) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include: * Screening for eligibility * Three MRI scans

The 1100 study is an open-label, Phase I, dose escalation and expansion prospective clinical study to assess the safety of intratumoral injection of NBTXR3 activated by radiotherapy in combination with anti-PD-1 therapy.
