Receiving a cancer diagnosis is difficult enough. But many people tell us that what worries them most is not just their illness, but a question that keeps coming back to them:

“What if this is hereditary? What if my children or my siblings could develop it too?”

At Nexus Oncology, we have created a dedicated hereditary cancer and genetic counseling unit to answer these questions with rigor and compassion. Our aim is not to frighten, but to shed light on the issue, assess the actual risk, and, when necessary, act promptly with personalized prevention and early diagnosis plans.

Genetic counseling and hereditary cancer

Most cancers occur sporadically, with no direct link to heredity. However, in a percentage of cases, there is an inherited genetic mutation that can significantly increase the likelihood of developing certain tumors (breast, ovary, colon, prostate, pancreas, melanoma, and others).

The goal of genetic counseling in cancer is precisely to determine whether cancer cases in your family are due to chance or a hereditary predisposition .

It may be helpful to request a hereditary cancer assessment when situations such as the following are observed in the family:

  • Several cases of the same type of cancer (for example, several breast, ovarian, colon cancers…).
  • Diagnoses at particularly young ages .

  • Bilateral or multiple tumors (for example, breast cancer in both breasts, or the same person with two different primary tumors).
  • Rare cancers, such as breast cancer in men or certain rare tumors.
  • Accumulation of tumors in the same family branch (maternal or paternal).

  • A family member with a known genetic mutation linked to cancer.

Having one or more family members with cancer does not automatically mean that there is a hereditary syndrome, but it may justify a specialized assessment to objectively measure your risk.

Our goal is not just to do a “genetic test”, but to accompany you throughout the entire process of understanding and decision-making .

Follow-up and early detection consultation

When we identify a hereditary mutation or a clear familial aggregation, the next step is to design a personalized monitoring and early detection plan .

At Nexus Oncology we don’t just focus on the test result: we transform it into a concrete action plan .

What does personalized follow-up consist of?

Depending on the gene involved, the type of associated tumors, and your age, we develop a protocol that may include:

  • Mammography and/or breast MRI at younger ages and more frequently.
  • Colonoscopies initiated earlier than usual and repeated at shorter intervals.
  • Gynecological ultrasounds, specific analyses or other tests adapted to each syndrome.
  • Full body magnetic resonance imaging
  • Preventive surgery in highly selected cases.
  • Use of certain drugs that can reduce the risk of developing certain tumors.
  • Specific lifestyle recommendations.
  • Which family members should consider genetic testing?
  • At what age is it advisable to start monitoring children or other relatives?
Hereditary cancer

This entire plan is always explained calmly, taking into account your preferences and your current life stage. It’s not about “filling your schedule with tests,” but about balancing prevention, early detection, and quality of life.

How often is the plan reviewed?

The monitoring is not static. We review it periodically:

New scientific evidence about the gene involved.

Changes in your personal or health situation.

Results of the tests performed.

If science advances and new recommendations or preventative options emerge , we update your protocol so that it is always aligned with the latest knowledge.

Patient stories

Behind every diagnosis is a person, a family, and a story of resilience. In this section, we share real-life cases of patients who, with the right medical care, human support, and hope, have journeyed their own path to recovery.

Is it time to schedule a genetic counseling appointment?

If you recognize yourself in any of these situations:

  • You have several family members with the same type of cancer.
  • You have been diagnosed with cancer at a young age.
  • In your family there are rare or recurring tumors in several generations.
  • You know there is a genetic mutation in a family member and you don’t know what it means for you.

genetic counseling at Nexus Oncology can help you:

  • Measure your real risk of hereditary cancer.
  • Decide if it makes sense to do a genetic test.
  • Design a monitoring and early detection plan tailored to you and your family.

Our genetic and genomic studies for familial cancer

At Nexus Oncology , we work with genetic panels specifically designed for hereditary cancer , based on next-generation sequencing (NGS) technology. This allows us to precisely study many genes involved in cancer predisposition , using only a simple blood sample.

Not all patients need the same test. That’s why we first listen to your family history and design the most appropriate study strategy. Only then do we select the genetic panel that best answers the questions in your case.

Specific genetic panels by cancer type

We have panels targeting the most common hereditary cancer syndromes, among others:

  • Familial breast and ovarian cancer: Studies that include BRCA1, BRCA2 and other genes related to hereditary breast and ovarian cancer , useful when there are several cases in the same family branch or diagnoses at young ages.
  • Colon cancer and Lynch syndrome: Panels for familial colorectal cancer and for Lynch syndrome (nonpolyposis colon cancer and associated tumors such as endometrium, stomach, ovary, etc.).

  • Endometrial cancer and hereditary gastric cancer: Specific panels when these tumors predominate in the family or there are typical combinations of certain syndromes.

  • Hereditary melanoma, pancreatic, prostate and kidney cancer: Studies focused on families with multiple cases of melanoma , pancreatic cancer , prostate cancer or kidney cancer diagnosed at younger than usual ages.

“Pancancer” panel and rare syndromes

In some families, the pattern of tumors does not clearly fit into a single syndrome. In these cases, a “pan-cancer” panel , which analyzes around 150 genes related to hereditary predisposition to different types of cancer, can be useful.

We also have panels for less common syndromes , such as:

  • Cowden syndrome .
  • Li-Fraumeni syndrome .
  • Multiple endocrine neoplasia (MEN) .
  • Neurofibromatosis .
  • Rasopathies .
  • Paraganglioma-pheochromocytoma syndrome , among others.

These studies make it possible to identify specific mutations that can explain the pattern of cancer in the family and, above all, help to define which family members are at risk and what prevention and follow-up measures they need .
