What Causes Discrepancy In Grading Breast Cancer?
See the discription.
Detailed Answer:
Hi,
Thanks for trusting us for your trouble.
I feel really sorry about your problem.
Staging of cancer defined the extent of cancer in the body.
Staging plays a very significant role in treatment and prognosis of patients.
In your instance if your breast cancer staging is 3 that means the tumor is situated in breast tissue as well as lymph node in axilla and breastbone and affecting the chest wall also.
In stage 3 there is sub staging like 3A, 3B, 3C depend upon how many axillary lymph nodes involved and depend on the tumor size.
If it is stage 4 that means the tumor has distant metastasis means it spread in your other body organ like lungs, bones, liver and other organ etc.
Thus if you are in stage 4 the tumor is inoperable (Surgery is not possible) and the prognosis is not very good, but if it is in stage 3 then there is some chance of removal of tumor with surgery and the prognosis is much better than stage 4.
Hope I have answered your query if you have further questions I will be happy to assist you.
Good luck.
God bless You.
