I am wondering about healthy blood counts while  undergoing chemo and how low it can go.  I am 50% done with a 4 treatment regimine for breast cancer. I am 48, about 130lbs, my license says 5 but thats pushing it. I am a week out of second chemo, today my hemoglobin was 11.2, wbc 4.5 and platelet 291. My oncologist said its all good, but I am curious about to see if it is on low side and how low it can go with my treatments.
There is lowering of counts immediately after chemo but in the intervals between regimes body makes up that to near normal levels, also supportive medicines are given for building up hemoglobin and diet modification done. You may inquire and follow up with your oncologist or a general physician with whom you should be in touch, This can be monitored.
