If your cancer comes back more than six months after completing your chemotherapy, your cancer is probably what oncologists call “platinum sensitive”.
You can be treated with platinum-based combination chemotherapy (i.e. treatment containing the drugs cisplatin or carboplatin), sometimes the same treatment you originally had.
If your cancer comes back within six months of completing your treatment, it means your cancer is resistant to the chemotherapy you were given.
There are options available to your medical team and they will be able to try a different combination of drugs from those you received initially. They might also discuss you entering a clinical trial of a new anti-cancer medication designed to overcome chemotherapy resistance.
When cancer comes back you may wish to seek a second opinion and this is your right.
You can discuss this with your oncologist or GP.
