Study Summary

This trialstudies a new form of radiation therapy to treat breast cancer before surgery that may work better and have fewer side effects.

Who is the study for?
This trial is for individuals with confirmed breast cancer, clinical stage T0-T2 N0 M0, who can consent and complete tests. They must be able to visit the institution for follow-up and are planning surgery with whole breast radiotherapy. It's not for pregnant women, those not using contraception, prior chest radiation patients, recurrent cancer cases or people with severe illnesses.Check my eligibility
What is being tested?
The study is examining hypofractionated radiation therapy before surgery in breast cancer patients. This method involves higher doses of radiation over a shorter period than traditional treatments, potentially improving tumor control with fewer side effects.See study design
What are the potential side effects?
While specific side effects aren't listed here, hypofractionated radiation generally may cause skin irritation at the treatment site, fatigue, mild swelling or tenderness in the treated area. The approach aims to reduce overall side effects compared to conventional radiation.
