Invasive lobular carcinoma of the breast
I had invasive lobular carcinoma as well. Not too many of us on these boards with this type of cancer. I know you don't really want to do surgeries but if your overall health is good you should consider it. This type of cancer does have bilateral tendencies so if you're going to move forward I'd get them both done at the same time. If you have not had an MRI I would suggest doing so before having any surgery. That will pinpoint everything they see and may offer more information. It did for me. It took my 1.5 cm mass and proved it was really 10 cm.
Our type of cancer tends to grow very quickly. Yours is already into your chest wall muscle and for me, when I had my mastectomies, they had to remove most of my chest wall muscle because they were trying to get clear margins. They do also need to at minimum do a sentinal node biopsy during your surgery. This can all be done at once. I had one night in the hospital with my mastectomy. Really that was all that was needed. Most women don't even do that much, they leave a few hours later.
The numbers T1-T4 describe the size and/or how much the cancer has grown into the breast tissue. The higher the T number, the larger the tumor and/or the more it may have grown into the breast tissue.
As for hormone therapy, they will most likely put you on an AI afterwards to stop/block estrogen from being produced in your body. Even though you are menopausal it's still produced by the adrenals and the fat in our bodies.
