Why might your oncologist not be concerned about a small spot on your breastbone while your primary tumor is shrinking?

Your oncologist may not be worried because chemotherapy works cumulatively in your body, and it takes time for the treatment to reach all areas effectively. Since your primary tumor is responding well and shrinking after three rounds, this is a positive sign that the treatment is working.

Some areas of the body naturally have less optimal blood circulation, which means chemotherapy may take longer to reach those spots. Areas near bones, previous injuries, or scar tissue can have reduced circulation, so these regions might respond more slowly to treatment.

Your doctor is likely monitoring the spot through imaging tests and may be waiting to see how it responds over additional treatment cycles. If your scans show the spot is stable or shrinking, even slowly, this suggests the chemotherapy is doing its job.

However, if you're feeling uneasy about it, trust your intuition. It's completely reasonable to ask your oncologist to explain their reasoning more clearly or to discuss what signs would prompt further investigation. Getting clarity can help ease your concerns while you continue treatment.
