Ovarian cancer often presents with vague symptoms that mimic common digestive issues, leading to delayed diagnoses in many cases. Metropoles reported the case of endocrinologist Mari Cançado, who lived with persistent fatigue and indigestion for eight months before receiving a stage 4B high-grade serous ovarian cancer diagnosis.
Overlapping Symptoms Complicate Early Ovarian Cancer Detection
The early signs experienced by Cançado included an enlarged lymph node, persistent fatigue, digestive discomfort, and changes in bowel habits. She also reported muscle weakness and lower back pain when lying flat. According to Jacqueline Menezes, a surgical oncologist and national director of the Brazilian Society of Surgical Oncology (SBCO), these symptoms frequently overlap with gastrointestinal problems, complicating early detection.
There is currently no universally accepted screening method to reduce mortality in asymptomatic women. While transvaginal ultrasounds are used to investigate specific symptoms, medical experts emphasize that these are not routine screening tools for healthy individuals. When symptoms arise, clinical investigation may involve blood tests, abdominal imaging, and biopsies.
Late-Stage Presentation Statistics
Data from the SBCO’s 2023 Hospital Cancer Registry highlights the difficulty of early detection. Among 855 recorded ovarian cancer cases where the stage was specified, 588—or 68.8%—were diagnosed at stage 3 or 4. These figures reflect the patient population at participating hospitals, illustrating the clinical reality where many patients seek care only after the disease has advanced.
BRCA2 Mutation Enables Use of PARP Inhibitors
Following a recurrence of her cancer, Cançado underwent genetic testing, which revealed a mutation in the BRCA2 gene. Identifying this mutation allowed for the use of PARP inhibitors, a class of targeted therapy that interferes with the ability of tumor cells to repair their genetic material.
Menezes notes that BRCA mutations can be either hereditary or confined to the tumor itself. If the mutation is inherited, it provides crucial information for the patient’s family members, who may then undergo genetic counseling and testing for cancer predisposition. Cançado has remained in remission for several years while managing her condition with oral medication.
Clinical Guidance on Genetic Testing
Current medical consensus suggests that genetic counseling should be offered to all patients diagnosed with epithelial ovarian cancer, regardless of their family history or age. When a hereditary mutation is confirmed, it opens a pathway for relatives to receive specialized monitoring from oncogeneticists.
What Are the Warning Signs of Ovarian Cancer?
What are the primary warning signs of ovarian cancer?
Patients should monitor for persistent abdominal bloating, pelvic or abdominal pain, a feeling of fullness after eating small amounts, changes in bowel habits, and increased urinary frequency. These symptoms become concerning when they are persistent rather than occasional.
Why is screening for ovarian cancer difficult? There is no screening test for ovarian cancer that has been proven to reduce mortality in the general population.
What happens if a BRCA mutation is found?
If a patient is found to have an inherited BRCA mutation, it allows oncologists to use targeted therapies like PARP inhibitors, which can be more effective for that specific tumor type. It also triggers a process of cascade testing, where close relatives are offered genetic screening to determine if they carry the same mutation and require increased surveillance or preventative measures.
