My mother did the same, at about the same time.
and she is also fine today
Stage 3 Stomach Cancer survivor here. Took VERY strong dosage rounds of four chemo cocktail to begin with, THEN full stomach removal and 15 lymph node removals, then follow up four rounds of pill Chemo.
Clear pathology, clear scans 2 years and 3 month after diagnosis. Very strong and nasty side effects but the strong chemo is what saved me I believe. My Oncologist used a treatment plan out of Sloan Kettering protocols and my surgeon was an oncologic surgeon at MD Anderson. My tumor wasn’t just dead, it was gone completely.
The key is finding an oncologist that is always using the latest top protocols and treatment programs.
