Hi. Take a breath, and then get on the phone to your doctor. You can ask to talk to the doctor or the nurse to find out if you need to come in early. They shouldn't mind if you call, remember, they work for you. Never be hesitant to get the information you need from your doctor.
i av unexplained bruises come up on my leg is it anything to worry about
Just have some clarifications. Are you taking some form of medication/s now? Do you have other illnesses aside from breast cancer?
The bruises you are having could be an idiosyncratic reaction from a drug that you may be taking. It could also be caused by a blood disorder. Patients with liver problem can also have spontaneous bruising. I agree with the other post that you should consult your doctor for evaluation.
