i have a invasive carcinoma that is well differentiated with a grade of 1 is this good will this he

Laura, see my answer to your other question— yes, this is relatively "good." And it's a big part of staging your cancer. Here's some informaiton on staging that might help you understand it. Good luck! PJH

Staging determines what kind of treatment you have, but it refers to the following: size of tumor; lymph node involvement; and spread of cancer outside the breast. The pathology report will include information on these three key indicators, and the combination of answers it provides determines your cancer stage, as follows:

Stage 0: This generally refers to pre-cancerous cells (hyperplasia), with no lymph node involvement and no metastasis (spread) to other parts of the body.
Stage 1: Your tumor is smaller than 2cm (a centimeter measures about 1/3 inch), with no lymph nodes involved and no metastasis.
Stage 2: Your tumor is smaller than 2cm, but there’s at least one lymph node involved; OR your tumor is between 2cm and 5cm, with no lymph node involvement. In either case, there’s no metastasis.
Stage 3: There’s no metastasis, but one of the following is true:
•Your tumor is smaller than 5cm, with “fixed” lymph node involvement, which means the lymph nodes are connected to one another or to other structures;
•Your tumor is larger than 5cm (with or without lymph node involvement), and has also spread to the chest wall or skin.
Stage 4: Your tumor is any size; your lymph nodes are or aren’t involved; but the cancer has spread to another part of your body. 

Obviously, the lower your cancer stage, the better your prognosis.

Laura - Grade 1 is very good when it comes to staging!

Grade 1 refers to "Well Differentiated" They look the most like normal cells.  Tends to be slow-growing and less likely to spread to the lymph nodes.

The Grade, combined with many other factors  (such as tumor size, if nodes are involoved, if it has metatasized, whether you are er+ or pr+, if you're HER-2/neu or not, etc.) is what determines your "staging".

Generally speaking, the lower the stage, the less the spread & the higher the survival rate.

Based on that information it seems like your prognosis may end up quite well.  Good luck to you!  Keep us posted!
