Hearing the words “you have cancer” is often followed by a second wave of uncertainty: what happens now? For many patients and families, the period immediately after diagnosis can feel busy, slow, and overwhelming at the same time.
There may be appointments, scans, blood tests, and unfamiliar medical terms — sometimes before any treatment even begins.
These steps are not delays. They are a structured and essential part of oncology care designed to ensure that treatment decisions are based on a clear and accurate understanding of the cancer and the patient’s overall health.
A cancer diagnosis is usually confirmed through a biopsy or tissue sample examined by a pathologist. That report confirms the presence of cancer and identifies the type, but it is rarely the only information needed before treatment can begin. Two people may have cancers that appear similar, yet require very different treatment approaches because cancers behave differently, respond differently to medicines, or may have spread in different ways.
In regional communities across Northern KwaZulu-Natal, understanding this process is especially important.
Many patients expect treatment to begin immediately after diagnosis and may feel anxious when further tests are requested. Knowing why these steps are necessary helps reduce uncertainty and builds confidence in the care pathway.
After diagnosis, oncology care focuses on answering important questions. What exact cancer type is this? How advanced is it? Has it spread, and if so, where? Are there biological features that influence treatment choices? What treatments are likely to help? What is the person’s overall health status?
This is why patients are often sent for additional tests before treatment begins. These tests are not about postponing care; they are about ensuring that the right treatment is chosen from the start.
A cancer diagnosis can feel like the ground shifting beneath your feet — sudden, overwhelming, and full of unknowns.
“As a clinical and radiation oncologist at Melna Oncology Centre in Newcastle, KwaZulu-Natal, I have walked this path with countless patients,” explains Dr Buthelezi-Zulu.
The good news is that the initial diagnosis is only the starting point. It is like seeing smoke from a fire — we need to investigate further to understand the full picture before deciding how best to respond.
Further tests after diagnosis are not about doubting the first result; they are about building a complete picture to guide the best possible care. Imagine your body as a map: the initial biopsy or scan identifies where the cancer is, but it does not reveal the full terrain.
Is the cancer confined to one area, or has it spread to nearby tissues or distant organs? Tests such as CT scans, PET scans, MRIs, blood work, or genetic profiling help answer these questions with precision.
These steps allow clinicians to stage the cancer accurately — determining its size, type, and reach — which directly influences the treatment plan.
For example, early-stage breast cancer may require surgery and monitoring, while more advanced disease may benefit from targeted systemic therapy and/or chemotherapy and radiotherapy.
Without this detail, treatment decisions would be made without adequate information, risking overtreatment or undertreatment.
Think of it as careful detective work: gathering the right clues to tailor therapy to the individual patient’s cancer, rather than applying a generic approach. Modern investigations are often quicker and less invasive than many patients expect, and they help replace fear with understanding.
In clinical practice, many patients find that once they understand their treatment roadmap, anxiety begins to shift into action and confidence.
Understanding Staging
One of the most important parts of this process is staging. Staging is a structured way of describing how much cancer is present in the body and how far it has spread.
Different cancers use different staging systems, but staging generally helps clinicians plan treatment and discuss expected outcomes accurately.
For many cancers, staging considers the size or extent of the primary tumour, whether nearby lymph nodes are involved, and whether there is spread to distant organs.
Staging is not about labelling the patient — it is about selecting the correct treatment approach.
Staging is not always completed on the same day as diagnosis. Results may arrive over days or weeks, particularly when specialised pathology or molecular testing is required. The aim is to build an accurate understanding of the disease before treatment decisions are made.
Staging effectively maps the cancer using systems such as TNM — T for tumour size, N for lymph node involvement, and M for distant spread. It may also include molecular markers that influence treatment decisions.
These details are not labels; they are facts used to guide the most appropriate treatment path — surgery for localised disease, or combined approaches for more advanced stages.
This process, while sometimes taking days or weeks, ensures that treatment is informed and precise. Patients often feel more empowered once they understand this personalised roadmap.
The Role of Pathology, Molecular Testing and Imaging
Pathology provides more information than simply confirming cancer is present. It can identify the specific subtype of cancer and features that influence how the cancer behaves and how it may respond to certain treatments.
In some cases, additional molecular testing of the tumour is recommended to help guide therapy choices. This may include identifying specific markers, such as HER2 in certain breast cancers, which can directly influence treatment selection.
Imaging and scans are also often required at this stage.
Different scans provide different perspectives, helping confirm the stage of disease and identify areas that may require treatment.
Scans can also help determine whether surgery is feasible, how radiotherapy treatment can be accurately planned, or whether medicines may be more appropriate as a first step.
Waiting for scan results can be difficult, but accurate staging remains an essential part of responsible, evidence-based care.
At Melna Oncology Centre, these diagnostic steps are carefully coordinated so that imaging, pathology, and staging information are brought together before treatment planning begins.
Radiotherapy and Continuity of Care
Radiotherapy is another important treatment used in the management of many cancers. It uses carefully directed high-energy beams to damage cancer cells and may be applied with different goals — curative treatment, reducing recurrence risk after surgery, shrinking tumours before surgery in selected cases, or controlling symptoms such as pain or bleeding.
Because radiotherapy equipment is highly specialised and not available in every town, patients from regional areas may need to travel to external centres for treatment. When this happens, continuity of oncology care remains essential. Radiotherapy is seldom used as a standalone treatment.
With certain exceptions, such as some cases of meningioma where radiation alone may be appropriate, it is typically incorporated into a broader, carefully coordinated treatment plan.
At Melna Oncology Centre, radiotherapy planning is coordinated under the supervision of Dr Thandeka Buthelezi-Zulu, with treatment delivered at established partner centres where required.
Care remains continuous throughout the process, with patients supported before, during, and after treatment to ensure consistency, clinical oversight, and minimal disruption.
Why Treatment May Not Start Immediately
Patients often struggle to understand why treatment does not begin immediately after diagnosis.
During this period, it can feel as though little is happening, when in reality essential clinical work is taking place behind the scenes. Completing staging investigations and finalising a carefully considered treatment plan are integral parts of responsible oncology care.
Starting treatment without adequate information can result in inappropriate therapy choices, unnecessary side effects, or the loss of important options such as surgery, radiotherapy, or targeted therapies. What may appear to be a delay is often a deliberate and medically necessary step to ensure that treatment begins on the strongest possible footing.
In oncology, urgency matters — but it must always be balanced with accuracy in order to achieve the best possible outcome.

FAQs: What happens after a cancer diagnosis?
After a cancer diagnosis, patients usually undergo further tests such as scans, blood work, and sometimes molecular testing. These help determine the type, stage, and behaviour of the cancer so that the most appropriate treatment can be planned.
Additional tests are needed to fully understand the cancer. They help determine how advanced it is, whether it has spread, and what treatment options are most suitable.
Cancer staging is a way of describing how much cancer is in the body and how far it has spread. It helps doctors decide on the most effective treatment approach.
A short delay allows doctors to gather all necessary information before starting treatment. This helps avoid incorrect treatment choices and ensures the best possible outcome.
Treatment options may include chemotherapy, targeted therapy, immunotherapy, radiotherapy, or surgery. The choice depends on the type of cancer, its stage, and the patient’s overall health.
No, cancer treatment is personalised. Even patients with the same type of cancer may receive different treatments based on their specific condition and medical factors.
Radiotherapy uses high-energy beams to target cancer cells. It may be used to cure cancer, reduce recurrence risk, or relieve symptoms, depending on the case.
Follow-up care helps monitor how well treatment is working, manage side effects, and adjust treatment when necessary to support long-term outcomes.
