Medical Oncologist in Guatemala City
Your diagnosis has a name. And it deserves an oncologist who knows it.

initial consultation with complete case review and treatment plan
Every solid tumor has a treatment protocol.
Dr. Reynoso treats every solid tumor in adults — not just those with a dedicated page on this site. For less common diagnoses, the approach is the same: complete molecular diagnosis, up-to-date protocol based on ASCO and ESMO guidelines, and real time to understand each case.
Some tumors — like kidney, bladder, or pancreatic cancer — don't have the same visibility as breast or lung cancer, but they still have well-defined, up-to-date treatment options. The common problem is finding an oncologist in Guatemala who knows them and applies them correctly. Dr. Reynoso reviews every case with the same rigor, regardless of tumor type.
“If your diagnosis isn't on my list of specialties, that doesn't mean I can't help you. It means your tumor is less common — but it still has a treatment protocol that I know and apply.”—Dr. Giovanni Reynoso
Solid tumors with care available in Guatemala
This is a non-exhaustive list of solid tumors Dr. Reynoso treats in addition to his main specialties. If your diagnosis isn't listed here, consult directly — he can likely help you too.
Do you identify with any type of cancer?
A first one-hour consultation is enough to begin your workup and, if applicable, reach a clear diagnosis
The same rigor regardless of tumor type.
Dr. Reynoso's diagnostic and therapeutic approach is the same for every solid tumor — whether it's a common diagnosis or a rare one.
Complete case review
Detailed medical history, biopsy result, imaging studies, available molecular markers, and prior treatments received.
Identification of relevant molecular markers
Every tumor type has molecular markers that can change treatment. Dr. Reynoso reviews which ones have been done and which are missing — regardless of tumor type.
Staging and resectability assessment
Stage classification according to the current system for that tumor type. Assessment of whether the disease is localized, locally advanced, or metastatic — and whether the treatment goal is curative or disease control.
Applying ASCO and ESMO guidelines
Dr. Reynoso applies current ASCO and ESMO guidelines for each tumor type — the same ones used by the world's leading oncology centers. No generic protocols or outdated treatments.
Multidisciplinary coordination when applicable
Tumors requiring surgery, radiotherapy, or other specialties are managed in coordination with the corresponding team — gynecologic oncology, surgery, hepatology, endocrinology.
Treatment plan and follow-up
A clearly defined systemic treatment protocol — which agent, what dose, what goals, and how response is monitored. A full hour to explain it without rushing.
Why consult Dr. Reynoso for your tumor?
ASCO and ESMO guidelines for every solid tumor
ASCO and ESMO guidelines cover every solid tumor — not just the most common ones. Dr. Reynoso applies them to every diagnosis, whether it's a common tumor or a rare one in Guatemala.
Identification of molecular markers not yet performed
In rare tumors, relevant molecular markers are often not requested — because the previous physician didn't know about them or didn't consider them. Dr. Reynoso reviews what's missing and how to obtain it.
Second opinion for uncommon tumors
An uncommon tumor in Guatemala may have very specific treatment protocols that aren't always applied locally. Dr. Reynoso reviews the case with up-to-date judgment — without assuming that what was proposed is necessarily correct.
A full hour to understand your case
Regardless of tumor type, every patient receives a full hour of consultation — to review the studies, explain the diagnosis, and build a plan that makes sense for that specific person.
