Skin dying after surgery

I had a Left mastectomy along with a tram flap reconsrtuct 7 weeks ago I seem to be a long way from being healed, as instill have open wound on lower incision of flap. I am suposed to start Chemo this week. Will chemo stop the healing and should I wait? Is it common for the skin to die at surgery sight?

Dear mouse31, The concern with giving chemotherapy in a situation of a non-healing wound is concern of infection as well as further delay to healing. The decision regarding when it is safe to give chemotherapy needs to be based on the risks and benefits to the patient in the individual situation.  Your oncologist and surgeon will need to evaluate and discuss with you these risks and benefits in regards to you.   It is not common for the skin to die at the surgery site.

Since my skin dying is not "normal".  What are possible solutions?  My Plastic Surgeon says I will be fine and not to worry about it . The skin will eventually heal together, but will not look the same.   Oncologist is concerned and will not start chemo unless she signs off.  Second opinion by another plastic surgeon within the same group, says - would proceed with caution and have weekly visits with the plastic surgeon to watch for infection. I am completely hysterical because no one will give me an honest answer . I have already been delayed in chemo one month and am in stage 3.    The surgeons report from the initial surgeon shows the skin was pink and viable when she was done.  what do I do.  Get a third opinion,  hire an atty?
