Hi @Chelley59 - you have to heal from the 2nd lot of surgery before the rads can start - so you went back to the starting block (sort of) for the 2nd lumpectomy. Your surgeon will be able to give you a rough idea, depending on the amount of surgery that you had. Rads can be anything from 4 weeks even up to 12 weeks post op .... and with Xmas looming, it may be put off until Jan, as the public holidays may impact the rads (usually it is Mon-Fri for 3-6 weeks depending on the recommendation) and they don't want you to miss a couple in the middle due to public holidays .....
Mine was 'detected' in Nov & being rural, didn't get MG & US until early Dec (which was undecided) so had a core biopsy on Dec 27th, diagnosis of cancer on Jan 5. Couldn't even SEE a surgeon until Mid January (as they take Xmas holidays as well!) and had surgery Jan 17th. My rads was finished the day before Good Friday (tho my Rad Onc said I could wait until 3-4 weeks after if I wanted to do it after my holiday to Norfolk Island.) I chose the earlier date so I could enjoy my hols after the rads had finished.
There is no 'strict' guideline. But the waiting is still the pits! :(
Take care, all the best for your ongoing treatment - hope you have some specific dates after you see the surgeon xx
