The pbs only covers herceptin in conjuction with chemo. This is because clinical trials demonstrated this was the most effective combination. So usually the very minimum if node negative would be taxol and herceptin. The taxol is over 3 months...the herceptin goes for a year. If you are not keen for radiotherapy the best option is for mastectomy.
When seeing the oncologist do ask about the ki67 rate...or division rate of your tumour. Ask about the percentage of advancement based on evidence with and without treatment.
That is good @Londog, and the ki67. Any further thoughts about chemo or still unsure? Does your surgeon have a timeline for when you should start, if you start? Hope you're not too uncomfortable tonight. K xox
