Hereditary Breast and Ovarian Cancer Syndrome (HBOC)

Introduction

Have you ever heard of Hereditary Breast and Ovarian Cancer Syndrome (HBOC)? This genetic disorder largely affects women, though men can also be impacted. This article aims to provide an in-depth understanding of HBOC, its causes, symptoms, diagnosis methods and available treatment options.

What is Hereditary Breast and Ovarian Cancer Syndrome (HBOC)?

Hereditary Breast and Ovarian Cancer Syndrome (HBOC) is a genetic condition that significantly increases the risk of developing breast and ovarian cancers. These cancers often occur at a younger age than in those without the syndrome. It is primarily linked to alterations or mutations in the BRCA1 or BRCA2 genes inherited from parents. In specific communities, such as individuals of Ashkenazi Jewish descent, the chances of carrying these gene mutations are notably higher, with studies indicating that about 1 in 40 individuals from this group have a BRCA1 or BRCA2 mutation.

What Causes Hereditary Breast and Ovarian Cancer Syndrome (HBOC)?

The primary cause of Hereditary Breast and Ovarian Cancer Syndrome (HBOC) is the inheritance of harmful mutations in the BRCA1 or BRCA2 genes from one's parents.

Recognising the Symptoms of Hereditary Breast and Ovarian Cancer Syndrome (HBOC)

Identifying symptoms of Hereditary Breast and Ovarian Cancer Syndrome (HBOC) can be challenging because the syndrome itself doesn’t cause any specific symptoms. Instead, it raises the risk of developing specific cancers, especially breast and ovarian cancer.

In women, signs of breast cancer may include a new lump in the breast or underarm area, nipple discharge other than breast milk, or changes in the breast's size or shape. Ovarian cancer symptoms may present as abdominal swelling, pelvic discomfort, or chronic indigestion and nausea.

The Diagnosis Process for Hereditary Breast and Ovarian Cancer Syndrome (HBOC)

To diagnose Hereditary Breast and Ovarian Cancer Syndrome (HBOC), blood or saliva samples are taken from a patient to examine their BRCA1 and BRCA2 genes for any mutations.

Here's a step-by-step overview of diagnosing HBOC:

1. Reviewing personal and family medical history: A healthcare provider takes into account your personal medical history and family history of cancer to determine whether genetic testing would be beneficial.
2. Genetic counselling session: Before undergoing genetic testing for HBOC, it’s recommended to have a counselling session with a certified genetic counsellor.
3. Genetic testing: A healthcare provider takes a blood or saliva sample, which is analysed in a laboratory to check for mutations in the BRCA1 and BRCA2 genes.
4. Understanding the results: A negative result means no known harmful BRCA mutations were detected, while a positive result indicates the presence of harmful mutations.

What are the Treatment Options for Hereditary Breast and Ovarian Cancer Syndrome (HBOC)?

Although there's no specific Hereditary Breast and Ovarian Cancer Syndrome (HBOC) treatment, those diagnosed can take preventive measures that include:

• Regular cancer screenings: This involves routine mammograms and MRIs for breast cancer, regular pelvic exams and ultrasounds for ovarian cancer.
• Risk-reducing surgeries: Preventive surgeries like mastectomy (removal of breasts) or salpingo-oophorectomy (removal of fallopian tubes and ovaries) can significantly lower the risk of developing breast and ovarian cancers.
• Medication: Certain drugs can help reduce the risk of breast cancer in high-risk individuals.

HBOC versus BRCA - What's the Difference?

While the terms are often used interchangeably, Hereditary Breast and Ovarian Cancer Syndrome (HBOC) and BRCA are not the same. HBOC is a genetic condition that raises the risk of certain cancers, particularly breast and ovarian cancers, due to mutations in various genes, including BRCA1 and BRCA2. Therefore, although BRCA gene mutations are a key factor in HBOC, the syndrome itself is linked to mutations in other genes as well.

Who’s at Risk for Hereditary Breast and Ovarian Cancer Syndrome (HBOC)?

Identifying who's at risk for Hereditary Breast and Ovarian Cancer Syndrome (HBOC) largely depends on genetic factors and family history. Individuals with a strong family history of breast, ovarian, or other related cancers may have an increased risk of having HBOC.

The Outlook for Hereditary Breast and Ovarian Cancer Syndrome (HBOC)

While a diagnosis of Hereditary Breast and Ovarian Cancer Syndrome (HBOC) can understandably cause anxiety, it's important to remember that it does not guarantee cancer development. Early detection through regular screenings can lead to successful treatment and management.
