What is the rate of survival for stage 3 invasive ductal carcinoma?

More than 50%: This is a hard question. Invasive ductal carcinoma is the most common type of breast cancer. It depends on whether it's stage3a, b or c, and the time of survival. At 5 years after diagnosis, 50-60% of women with stage 3 breast cancer are alive. Other factors are age, receptor status of the tumor, number of lymph nodes involved, and treatment. Remember that survival is improving all the time!

Varies: Depends if it is stage 3a, 3b, or 3c. The survival is listed as 40% to 70% over 5 years. But that is only statistics, and cannot be applied to one person's disease without knowing the full details of all tumor biology and their response to treatments.
