9/2006 I was diagnosed with Invasive Lobular Carcinoma size was 6.2 cm E+ P+ and Her2 over expression. I tried some alternative treatment and the tumor reduced down to 4.8, still hormonal receptive. In March 2006, I had another core biopsy from a different doctor that did not know my history and those labs came back as Invasive Ductal Carcinoma. Still positive with the hormones except the estrogen had dropped by 30%, but the progesterone had increased by 1% and the proliferation rate had dropped by 50%. I was sent to a medical oncologist and he told me the Ductal or Lobular was irrelevant. I must have chemo immedialtey. The oncologists says taxol and herceptin to start with. The PET scan states "Discrete, focal area of uptake would be seen with a localizing brest mass-carcinoma, not clearly seen on the PET". Does this make sense? Is it true Lobular versus ductal is irrelevant? PLEEEEEEase Help?
