The HER2 tests take alot longer. I found out I had invasive idc and I didn’t see or talk to my surgeon till the her2 tests came back. Didn’t need a second biopsy. Just more time for the testing of the biopsy sample

If your biopsy results indicate lobular carcinoma but do not mention HER2 status, it might be a good idea to discuss this with your healthcare provider. HER2 status is important for determining the best treatment plan. Here are some points to consider:

- HER2 Testing: Generally, all women with invasive breast cancer undergo HER2 tests.
- Types of Biopsies: HER2 status can be determined from the same biopsy sample using tests like immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH).

Consult your doctor to see if additional testing is needed.

This finding confirms that it is cancer and that it started in the lobe, the other results regarding the biomarkers may take a bit longer to get back.
