I did not have a dual diagnosis like you, but when I was diagnosed, her2+ was a really bad thing because herceptin was not even approved for frontline therapy.
My tumor was grade 3 and anchored to my rib, so they said we are going to hit it with pretty much everything we have.
That included multiple surgeries, a chemo cocktail of Taxol, Adriamycin, and Cytoxin for 6 rounds which I was told was the maximum lifetime dose of at least one of those drugs.
Then came radiation for 6 weeks which was easy but exhausting.
I had my ovaries removed but they still gave me tamoxifen for 5 years and anastrozole for 10 after that.
The tests that determine the percentage of risk with or without endocrine therapy didn’t exist either, my doctor said if I wanted the best chance, take the medicine.
It wasn’t easy, it wasn’t debilitating either. I had to walk every day or I would be really stiff and I definitely have aged a lot faster than my peers, but I am still here to complain about it.
I would have done just about anything to not go through hard chemo again, although I would if it meant more time with my husband.
A lot of patients now don’t have to go through the whole thing, and that is awesome but sometimes we don’t really have a choice if we want the best chances.
I should add that I was in my 30s when this started.
Have your doctors recommended a treatment plan yet?
