I have invasive breast cancer and had a lumpectomy and sentinel lymph nodes removed 4 weeks ago. The lymph nodes were tested during surgery so I know they are clear which is wonderful. But the results aren’t back from the lumpectomy so I don’t know yet if I need more surgery or chemo before radiotherapy and hormone drugs. Surgeon says he thinks it’s just delays over the summer. Is 4 weeks a long time as if not I need to manage my expectations? Thanks
