Hi I had round 3 of chemo for TNBC 2 weeks ago and have found the last 2 days that I am bruising incredibly easily without even knowing I've banged myself. My arms and legs are covered in bruises. Is this normal side effect or something I should call about and get bloods checked? I'm unsure how long it takes for all blood count toget back to normal after each chemo session as know it is probably down to low platelet count.

Thank you for getting in touch. My name’s Emma, I’m one of the Cancer Information Nurses on the Macmillan Support Line. Welcome to the online community. I see that you have joined the breast cancer forum and hope that you find it helpful.
You didn’t mention which chemotherapy you are having, however one of the potential side effects of chemotherapy can be bruising. This can happen when the number of platelets (which bind together to stop bleeding when there is an injury) are low, which means that it can be more difficult for blood to clot, causing a bruise even if there has only been a mild injury.
It’s important that, if you haven’t already, you contact your chemotherapy unit today, to let them know about your bruising. They will be able to assess whether you need to have a blood test to check your platelet levels.
A full blood count, is a blood test that will check on the levels of different components within the blood, including the red blood cells, the white blood cells and platelets. As chemotherapy effects all cells which are dividing it can lower the number of all of these, which is why there can be the possibility of infection, bruising or bleeding and anaemia. The time when these cells are at their lowest number is called the nadir, and this is usually 7-14 days after chemotherapy. After this point, their numbers will begin to increase again, and will often do so on their own without needing any intervention or treatment, so that by the time you are due your next cycle of chemotherapy they have reached a level when treatment can be given, approximately 21-28 days after your last treatment.
It is always important, that if you notice any new, changing or worsening symptoms during any treatment, you let your chemotherapy unit know.
I hope you find this information helpful. Please don’t hesitate to get in touch if you would like to speak with us again.
Best wishes
