Hi, I'm reaching out to anyone who has experienced this: I'm 45 years old, diagnosed in June with early stage invasive breast cancer, had lumpectomy in August, strongly advised to have chemotherapy after Oncotype DX results. Started chemotherapy early October and have reached the half way stage but am having a massive wobble. Feel like I cannot continue with it. I have massive issues with the whole procedure, anything medical is a real challenge for me. I am a massive over thinker and need to know the ins and outs of everything but having this knowledge makes me feel worse about the chemotherapy. Knowing what it is doing to my healthy cells is a devastating thought. But the worst part is not knowing if the chemo will have actually done any good. I always had doubts about going ahead with it because of the uncertainty of ever knowing if it has worked. But I managed to keep a lid on that doubt up until now. And now my head and my heart are shouting STOP! I've spoken to the specialist nurse who was amazing and reassuring and supportive. She suggested posting on a forum amongst other things. So I'm giving it a go. Ultimately I know there is only me who can make the decision but I Would really appreciate your views/experiences.
