This most certainly does not guarantee you freedom from recurrence or metastasis, although that does happen in some cases. With ACC, as with other rare cancers, it is always best to get a second opinion on initial diagnosis. Hopefully, this will give you the choice of two specialists from the very beginning of your ACC journey. If you are truly uncomfortable with your primary oncologist, then you should consider a change. It is totally dependent on how the disease has affected your overall ability to function, either physically or emotionally.
Counseling is a very private decision.
Keep in mind that you have been diagnosed with a relatively rare cancer that often acts quite differently from more common cancers. This may at times, make you feel 'different' when talking with other cancer patients. Many of us have experienced this. Some of us believe that counseling has helped us to understand ourselves, our reactions, the reactions others, and our social interactions as we go through the many facets of this disease. However, counseling is not a mandatory element of your treatment.
