Your Oncologist will give you the long list of side effects from chemotherapy. You are literally take a type of poison which kills both cancer cells and other fast dividing good cells. It's a tough call. After having been through chemo, I would look long and hard at all sides of this. You can't tell if you are going to be the one the chemotherapy does irreparable harm and damage to your body. I came out of it with severe osteoporosis. Other women come out with heart damage that can't be repaired. A woman I worked with and my mother-in-law both died of the heart complication..... not their cancer's. There is no way to advise or describe how you will feel going through chemotherapy. It is a very tough struggle in which you have to depend on others to help get you through it. If you have a job, you may not be able to continue until you are through treatment. If you have children, they are going to be seeing a pretty sick Mommy. On top of that.... you will lose your hair, possibly eyelashes, eyebrows, too..... the worst of all....ugh.
Women need to choose the treatment options and be as aggressive as will make them feel they have done what is possible. Despite a low onco score, you really want to feel you have done every treatment available to you. If so, then it is really only up to you. My Onc and I discussed women who, no matter if a treatment is only going to be of 1% benefit to them, they still wanted it. This is your body, your choice, your life and if choosing to go ahead with a more aggressive treatment then it doesn't matter what anybody else advises.
I hope more weigh in on your question.... it's a tough one.
Take care, and good luck, Sharon
