Medical oncology

What does a Medical Oncologist do?

I provide specialized, high-quality care for the diagnosis, treatment, and comprehensive follow-up of cancer.

My training at leading institutions in Mexico and abroad allows me to offer evidence-based medical care with a personalized, ethical approach centered on each patient's needs — walking alongside you through every stage of the illness.

Cancers I treat and coordinate
  • Breast & gynecologic: breast cancer (hormone receptor–positive, HER2, triple negative), ovarian, cervical, and endometrial cancer
  • Digestive: colon and rectum, stomach, liver and biliary tract, pancreas, esophagus
  • Lung: non–small cell (NSCLC) and small cell (SCLC)
  • Genitourinary: prostate, kidney, bladder, testicular
  • Skin: melanoma and other skin tumors
Available treatments
  • Neoadjuvant and adjuvant chemotherapy
  • Targeted therapy (anti-EGFR, anti-VEGF, ALK, BRAF)
  • Immunotherapy
  • Hormone therapy for prostate cancer
  • Coordination with surgical oncology, urology, gastroenterology, and radiation oncology
How I approach these cases

Biomarker testing comes first — the plan is built on the tumor's histology, stage, and identified mutations. I coordinate with the surgical or imaging specialist your case requires.

Let's talk about your case
Specialty

Other cancers.

As a medical oncologist, I don't treat only breast cancer. I care for solid tumors across different organs with the same approach: a precise diagnosis, a treatment plan tailored to your case, and support at every step.

I coordinate a multidisciplinary approach with surgical oncology, radiation oncology, and pathology to provide comprehensive, personalized care — whatever the type of cancer.

Colon & rectal cancer

Medical management of colorectal cancer: chemotherapy and targeted therapy, coordinated with surgery when your case requires it.

Stomach cancer

Systemic treatment of gastric cancer, with an individualized plan based on the tumor's biology.

Lung cancer

Chemotherapy and targeted therapies for lung cancer, within a multidisciplinary approach.

Ovarian cancer

Medical treatment of ovarian cancer, coordinated with gynecologic oncology and surgery.

Cervical cancer

Systemic management of cervical cancer, together with radiation therapy and surgery when appropriate.

Other solid tumors

If your diagnosis is another type of cancer, book an evaluation and we'll review it together.

How we'll work on your case
  • We review your biopsy and imaging studies together.
  • We define a tailored plan: chemotherapy, hormone therapy, or targeted therapy.
  • We coordinate with the surgeon, radiation oncologist, and pathologist as your case requires.
Book your evaluation
Specialty

Breast & gynecologic cancers.

As a medical oncologist, I completed an advanced fellowship in breast cancer at Mexico's National Cancer Institute (INCan). I also treat gynecologic tumors, given the close clinical and therapeutic relationship between the two areas. Which of these situations describes you?

Hearing the word "cancer" pulls the ground out from under you. At a moment like this, the most important thing is not to rush into decisions — it's to find an experienced specialist who can guide you with clarity, precision, and calm.

We coordinate a multidisciplinary approach together with surgical oncology, radiation oncology, and the other specialties involved, with the goal of providing comprehensive, precise, personalized care.

What you need to know
  • Not all cancers are the same. The subtype, the tumor's biology, and the stage determine most of the treatment.
  • "Surgery first" or "chemo first" is not universal. It depends on the tumor type, size, and extent.
  • The treatment plan is built together with the specialties your case requires — surgery, radiation oncology, pathology.
What we'll do
  • We review your biopsy report and imaging studies together, without the clock running.
  • We define the exact subtype and build an individualized treatment plan.
  • We coordinate with a surgical oncologist, radiation oncologist, and pathologist as your case requires.
Bring to your appointment
  • Complete biopsy (pathology) report.
  • Your most recent imaging studies (CT scan, MRI, ultrasound, or mammogram as applicable).
  • Additional studies if you have them (PET scan, bone scan).
  • A list of the medications you currently take.
  • Your questions, written down — as many as you like.
Book your evaluation

You're in the gray zone. It might be nothing, or it might be something — and the waiting is exhausting. The good news: the path to an answer is clear.

What you need to know
  • An abnormal finding or test result does not mean it's cancer. Most suspicious findings turn out to be benign once they're studied thoroughly.
  • A lump, a lymph node, or a spot on a scan is not a diagnosis on its own — a biopsy or targeted study is needed to confirm.
  • What helps: quickly defining which test comes next. Prolonged uncertainty does more harm than the answer.
What we'll do
  • We read your studies with you and explain every finding in plain language.
  • We order the next study if needed (targeted biopsy, tumor markers, additional imaging).
  • If it's benign, we confirm it with evidence. If it requires treatment, we don't lose time.
Bring to your appointment
  • The imaging study that raised the concern (printed report and disc or digital file).
  • Your most recent complementary studies.
  • Prior medical reports related to the finding.
  • Your family history of cancer.
Request your evaluation

You're the one holding the phone. You're screening clinics and comparing options. What you're looking for is someone who speaks to your loved one with respect — and gives you the complete information to support her well.

What you need to know
  • Your family member can come to the appointment accompanied. It's not just welcome — it's encouraged.
  • The explanation is also provided in writing if you need to share it with the family.
  • Questions between appointments have a channel: the doctor replies on WhatsApp during business hours.
What we'll do
  • We welcome the patient without rushing. The appointment lasts about an hour.
  • We explain the diagnosis in plain language — first to her, and then with you.
  • We build a plan you can share with the family, with timelines and referrals.
Bring to your appointment
  • Biopsy report (if there is one).
  • Mammogram, ultrasound, and any recent imaging studies.
  • A list of current medications.
  • Policy details if the patient has major medical insurance.
  • Your questions and hers, written down.
Request the first appointment

You already have a diagnosis and a treatment plan, but you want to confirm it with another specialist before deciding. Seeking a second opinion is standard practice in oncology — it isn't distrust, it's part of making the best possible decision.

What you need to know
  • A second opinion doesn't meaningfully delay your treatment — most are resolved in a single appointment.
  • It can confirm your current plan, adjust it, or open up options that hadn't been discussed with you.
  • The more complete your records, the more precise the review.
What we'll do
  • We review your complete file: biopsy, imaging studies, and the proposed treatment plan.
  • We give you an independent read, based on the evidence and your specific case.
  • If we agree with the current plan, we tell you plainly. If we see something different, we explain why.
Bring to your appointment
  • Complete pathology or biopsy report.
  • Imaging studies (with disc or digital file, not just the report).
  • The treatment plan proposed by your current doctor, if you have it in writing.
  • A list of current medications.

My approach — in my own words

My patients arrive afraid.

Sometimes they bring words on a piece of paper they don't understand: "invasive ductal carcinoma," "Ki-67," "HER2," "hormone receptor–positive." My first job isn't medical — it's to translate.

At Mexico's National Cancer Institute I learned that every tumor has its own biology, and that biology decides most of the plan. Two patients can tell me "I have breast cancer" and actually be talking about two different diseases. That's why I don't give generic plans.

I've seen women receive their diagnosis alone. I've seen entire families arrive at the office looking for an oncologist who won't rush them. That's why my appointments take as long as they need to — not five minutes. An hour is the minimum to review carefully, explain clearly, and leave you with a written plan.

As your oncologist, my commitment is to provide excellent care grounded in the best available scientific evidence, along with the time and attention to listen to you and accompany you through every stage of this process.

You can always count on me to answer your questions with honesty, empathy, and clarity.

FAQ

Frequently asked questions.

What most patients ask us before their first appointment.

How much does the first appointment cost?

The initial evaluation starts at $1,500 MXN (Mexican pesos).

I completely understand that cost matters. What I can assure you is that every appointment is focused on a highly specialized evaluation, with enough time to analyze your case thoroughly, review your studies, and answer your questions in depth. It lasts about an hour — it isn't an express consultation, it's the start of a plan.

Do you work with insurance companies?
Yes. We work with Mexico's leading insurers:
  • GNP
  • AXA
  • MetLife
  • Mapfre
  • Plan Seguro
  • Inbursa
  • Banorte Seguros
  • Allianz
If your insurer isn't listed, message us on WhatsApp before your appointment and we'll check.
What are your office hours?
  • Monterrey: Monday to Friday, 8:00 AM – 5:00 PM
  • Reynosa: Saturdays, 8:00 AM – 5:00 PM
If you need a time outside these hours, message us on WhatsApp and we'll check availability.
Should I send my studies in advance?
It's recommended, but not required. If you have them on hand, share them via WhatsApp so the doctor can review them beforehand — it saves time during your appointment. If you'd rather bring hard copies, that's fine too.
How long is the first appointment?
About one hour. Enough time to review your studies calmly, ask detailed questions, examine you if needed, and build a clear plan with you.
Do you see patients from outside Monterrey or Reynosa?
Yes. We see patients from across northern Mexico — Coahuila, Tamaulipas, Nuevo León, and surrounding areas — and from anywhere else. For out-of-town patients, we schedule the appointment with enough lead time for your trip.
Do you give second opinions remotely?
The first oncology evaluation is ideally in person — it includes a physical exam and a direct review of your studies. If distance is a real obstacle, message us on WhatsApp and we'll see what can be arranged.
How long does a biopsy result take?
It depends on the laboratory. In most cases, between 5 and 10 business days. If additional molecular studies are needed (full immunohistochemistry, genetic panels), it can take a few days longer.
Do you work as a team with other specialists?
Yes. Cancer care requires a multidisciplinary team. The doctor coordinates with the specialists your case requires — surgical oncologist, radiation oncologist, pathologist, gynecologist, or urologist.
How can I pay for the appointment?
We accept cash, bank transfer, and card payments (credit or debit) directly at the office.
