Investigation of Suspicious Lesions & Possible Cancer in Melbourne
An abnormal scan, enlarged lymph node or suspicious lesion does not automatically mean cancer. Many findings have benign explanations, while others need further imaging, biopsy or specialist review before the diagnosis is clear. Northern Blood & Cancer Care provides medical oncology assessment in Melbourne for selected patients with abnormalities that may represent cancer, including unexplained lymph node changes, bone lesions, liver lesions and lung nodules.
Depending on the finding, this may involve comparing previous scans, arranging more targeted imaging, obtaining tissue for pathology or involving another specialist such as a respiratory physician, surgeon, gastroenterologist, haematologist or interventional radiologist. Medical oncology is particularly useful when imaging or pathology raises a meaningful concern for malignancy or when a patient already has a cancer history and a new finding needs to be interpreted in that context.
Lymph nodes can enlarge because of infection, inflammation, immune conditions, lymphoma or cancer that has spread from another site. The location, size, pattern and duration of enlargement help guide investigation. Ultrasound, CT or PET imaging may be useful, but imaging alone cannot always determine the cause. When tissue is required, a core biopsy or excisional biopsy may be preferred because it can provide more information than a fine-needle sample in some situations. If lymphoma or another blood cancer is suspected, assessment can be coordinated with the haematology team.
A lung nodule is a small focal abnormality on chest imaging and most nodules are not cancer. Assessment considers the nodule’s size, shape, location, growth over time, smoking history, age and other risk factors. Some nodules are safely monitored with interval CT, while higher-risk findings may require PET imaging, bronchoscopy or image-guided biopsy. Respiratory physicians and radiologists often lead the initial nodule work-up. Medical oncology becomes particularly relevant once cancer is confirmed, when imaging strongly suggests advanced malignancy or when a nodule appears in a patient with a previous cancer.
The first step is usually to review the original imaging and compare it with any earlier scans. A finding that has been stable for several years may have a very different significance from one that is new or enlarging. The specialist also reviews symptoms, previous cancers, smoking and exposure history, recent infection, medications, blood results and the pattern of any other abnormalities on imaging.
When tissue is needed, the safest and most informative biopsy route is selected. This may involve ultrasound- or CT-guided biopsy through interventional radiology, bronchoscopy for selected lung lesions, surgical biopsy of a lymph node or another site-specific procedure. Pathology can then use morphology, immunohistochemistry and, where appropriate, molecular testing to identify the tissue of origin and biomarkers relevant to treatment. The goal is to avoid both unnecessary invasive testing and treatment based on an unconfirmed diagnosis.
If the investigation shows that a finding is benign, no cancer treatment is required and the patient may return to their GP or another relevant specialist for monitoring if needed. If cancer is confirmed, the next step depends on the tumour type, stage and whether the disease is localised or has spread. Patients can then move into the appropriate tumour-specific oncology pathway for discussion of surgery, radiotherapy, chemotherapy, immunotherapy, targeted therapy or other treatment.
Northern Blood & Cancer Care works with radiology, pathology, surgery, respiratory medicine, gastroenterology, haematology and other Melbourne services to coordinate the diagnostic pathway. Interventional radiology can be particularly useful when an image-guided biopsy is required. Where the eventual diagnosis is a blood cancer, the patient can transition to the practice’s haematology team; where a rare or highly specialised solid tumour is identified, referral to an appropriate tertiary multidisciplinary service can be arranged.
Please bring a current referral, medication list and all available imaging and pathology reports. Access to the actual imaging is helpful, particularly when the purpose of the consultation is to review a lesion or nodule found on a scan. If you have previously had cancer, bring details of the diagnosis and treatment, including operative and pathology reports where available. Your specialist will explain what the finding may represent, whether further imaging or biopsy is warranted and which specialist should lead the next stage of care. You are welcome to bring a family member or support person.
Northern Blood & Cancer Care brings together Melbourne specialists with complementary clinical, hospital and research appointments. The clinicians most closely associated with this service include:
A suspicious lesion on a scan is a starting point, not a diagnosis. Northern Blood & Cancer Care can review the clinical and imaging context, coordinate the most useful next investigation and help determine when biopsy, surveillance or referral to another specialist is appropriate. If cancer is confirmed, patients can move directly into the relevant oncology or haematology pathway with the diagnosis and staging information already brought together.
Northern Blood & Cancer Care brings together a highly experienced team of haematologists, medical oncologists and specialist physicians, with consultations available at Northern Private Hospital in Epping.
