Ductal carcinoma in situ

Hi @JEC the side effects of radiation just like with chemo vary from person to person, some people fly through it without a skin reaction or fatigue while others can get quite a bad reaction needing a break from treatment, there is just no way of knowing unfortunately. The main side effects are localised to the area so a skin reaction, loss of armpit hair on that side, possibly a sore throat if your nodes are being treated and then there is the fatigue. The side effects typically begin about 2 weeks in and peak 2 wks after as it is a build up effect. There is usually 25 treatments to the whole breast and then 5 treatments to a ‘boost’ area which is where the rumour was. There is a hypofractionated regime of 16 + 4 but this is not suitable for all women. Left sided patients may be asked to hold their breathe for treatment. You will be given a few permanent tattoo dots at your planning session. Care is taken to minimise dose to heart,lungs,ribs,spinal cord etc.
 I could go into lots of technical details all day haha. 
Best wishes and always happy to answer any questions xx
