Suggest Treatment For Invasive Lobular Carcinoma
This is a very good result.
Thank you for the query.
First and most information about her cancer is in what sage it has been detected. Stage of the cancer can be established when we know: tumor size, lymph nodes state (if there are any metastases in armpit lymph nodes) and if there are any metastases to other parts of the body.
Stage of the cancer is what gives the information about how advanced is the disease and what survival rate should she expect. For example, breast cancer limited to the breast only (no metastases in lymph nodes) and smaller than 2 cm is stage I. Breast cancer with no more than 3 regional lymph nodes metastases is stage II.
Invasive lobular carcinoma described the histological type of the cancer. It means that the cancer descents from milk-producing lobules of the breast. In contrast, invasive ductal carcinoma means that the cancer starts from milk ducts. For your daughter histological type does not make much difference with treatment or survival rate.
First of all few words about what receptor is. Receptor is a protein on the surface of the single cell. Lets call this protein a lock. Now every receptor can react to a specific protein (the protein connects with the receptor and sends signal inside the cell). This protein is a key. So receptor is a lock which can be open with a key (another protein).
ER/PR positive means that the cancer cell has on its surface receptors for estrogen and progesterone. This is very good information. This receptors gives the possibility to impact on cancer cells with antiestrogen medicine called Tamoxifenum. In simple words we have medicine which will prevent cancer cells from regrowing/giving metastases etc.
HER 2 negative is also very very good news. HER 2 is a special receptor for growing factor. If the cancer cell contains too much of this receptor, it multiply very fast. If the cancer multiply very fast, the cancer is aggressive.
In your daughter result also cancer cells grade is missing (it is marked with G and a number - G1, G2, G3). This also gives information about how aggressive is the tumor.
Hope this will help. Feel free to ask further questions.
