<s>[INST] I have been diagnosed with IDC breast cancer. So far I have been told that the ER and PR receptors are weakly positive (2% ER and 20% PR) and the HER2 is negative. I have also had an MRI which shows one suspicious lymph node which I will have an ultrasound/biopsy on next week. The mass in my left breast has measured at 3.2 CM. I have been told that the treatment should be 5 months of Chemo (ACT) and then surgery. I am wondering if I should be seeking a second opinion or if this course of treatment sounds correct. From discovery of the lump to now, it has only been a month so everything has been moving quite quickly. [/INST] Upfront chemo followed by surgery is one of the suggested therapy for early breast cancer. On chemotherapy the lump may decrease in size and later the surgery could be a breast conservation on rather than a radical mastectomy.. Hormon receptor status is weak . So hormone therapy may not be very useful.. You are ilon the right course... Continue with the same.. Thank you </s>
