What Does a Medical Oncologist Do?

Cancer treatment often involves a team of specialists.

A medical oncologist is a doctor who specializes in treating cancer using medicines and systemic therapies. Depending on the cancer, these treatments may include chemotherapy, targeted therapy, immunotherapy and hormone therapy.

The medical oncologist also plays an important role in:

  • Reviewing pathology and imaging reports

  • Assessing the stage of cancer

  • Selecting appropriate systemic treatment

  • Monitoring response to treatment

  • Managing treatment-related side effects

  • Coordinating care with other cancer specialists

  • Providing follow-up after treatment

  • Reviewing recurrent or metastatic cancer

  • Helping patients understand available treatment options

Depending on the disease, cancer care may also involve a surgical oncologist, radiation oncologist, pathologist, radiologist and other specialists.

Why Accurate Cancer Diagnosis Is Important

Effective cancer treatment starts with an accurate diagnosis.

There is no single test that can diagnose every cancer. Depending on the patient's symptoms and suspected cancer type, evaluation may include:

  • Medical history

  • Physical examination

  • Blood investigations

  • Ultrasound

  • CT scan

  • MRI

  • PET-CT

  • Endoscopy

  • Biopsy

  • Histopathology

  • Immunohistochemistry

  • Molecular or biomarker testing

For many cancers, a biopsy is required to establish a definite diagnosis. Tissue obtained during a biopsy is examined by a pathologist to determine whether cancer is present and identify its type and characteristics.

The pathology report can provide information that directly influences treatment planning.

Understanding Cancer Staging

After the diagnosis is confirmed, determining the stage of cancer is an important part of treatment planning.

Cancer staging helps doctors understand:

  • The size and location of the primary cancer

  • Whether nearby lymph nodes are involved

  • Whether cancer has spread to another part of the body

Depending on the cancer type, stages may be described as Stage I, Stage II, Stage III or Stage IV, although some blood cancers and other cancers use different staging systems.

Cancer stage can influence whether treatment involves surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, hormone therapy or a combination of treatments.

Biomarker and Molecular Testing for Cancer

Modern cancer care increasingly considers the biological and molecular characteristics of a patient's tumor.

Biomarker testing may look for particular genes, proteins or other characteristics within cancer cells that can provide useful information about treatment.

For selected cancers, biomarker testing may help determine whether a patient could benefit from a particular targeted treatment or immunotherapy.

Testing may be especially relevant in certain cases of:

  • Lung cancer

  • Breast cancer

  • Colorectal cancer

  • Ovarian cancer

  • Prostate cancer

  • Blood cancers

  • Other advanced or metastatic cancers

However, biomarker testing is not required for every patient, and finding a biomarker does not guarantee that a particular treatment will work.

The need for testing should therefore be assessed according to the cancer type, stage, pathology and clinical situation.

Cancer Treatment in Lucknow

Cancer treatment has become increasingly individualized.

Some patients require only one type of treatment, while others may need a combination of surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy or hormone therapy.

Treatment may also be given before or after surgery, depending on the cancer.

Chemotherapy

Chemotherapy uses anti-cancer medicines to kill cancer cells or stop their growth.

Depending on the diagnosis, chemotherapy may be used to:

  • Treat cancer

  • Reduce the size of a tumor before surgery

  • Reduce the risk of recurrence after surgery

  • Control cancer that has spread

  • Relieve symptoms caused by advanced cancer

  • Work together with radiation therapy

The chemotherapy regimen, dose and number of cycles vary between patients.

Before and during treatment, patients may require blood tests and clinical assessment to monitor treatment response and potential side effects.

Chemotherapy Side-Effect Management

Different chemotherapy medicines have different possible side effects.

These may include nausea, fatigue, reduced blood counts, hair loss, appetite changes, mouth problems or increased infection risk, although not every patient experiences all of these effects.

Supportive medicines, regular monitoring and timely communication with the treating oncology team can help manage many treatment-related problems.

Immunotherapy

Immunotherapy is a type of cancer treatment that helps the body's immune system respond to cancer.

One important group of immunotherapy medicines is known as immune checkpoint inhibitors.

Immunotherapy has changed the treatment landscape for selected cancers, including some lung cancers, kidney cancers, melanoma, head and neck cancers, bladder cancers and other malignancies.

However, immunotherapy is not appropriate for every cancer or every patient.

Treatment selection may depend on:

  • Cancer type

  • Cancer stage

  • Biomarker results

  • Previous treatment

  • Overall health

  • Potential benefits and risks

Patients receiving immunotherapy also require monitoring because immune-related side effects can sometimes affect healthy organs.

Targeted Therapy

Targeted therapy works against specific molecular changes or proteins that help cancer cells grow, divide or survive.

Unlike the idea of using the same medicine for every patient with a particular cancer, some targeted medicines work only when the tumor has a relevant target.

This makes molecular and biomarker testing important in selected cancers.

Targeted treatments may be considered for certain patients with:

  • Lung cancer

  • Breast cancer

  • Colorectal cancer

  • Kidney cancer

  • Ovarian cancer

  • Blood cancer

  • Other cancers with actionable molecular alterations

Whether targeted therapy is appropriate must be decided individually after reviewing the patient's pathology, stage and relevant test results.

Hormone Therapy

Some cancers depend on hormones to grow.

Hormone therapy may be used to slow or stop the growth of hormone-sensitive cancers, particularly some:

  • Breast cancers

  • Prostate cancers

Hormonal treatment may be used alone or in combination with surgery, radiation therapy, chemotherapy or other systemic treatments depending on the clinical situation.

Types of Cancer Treated

As a Cancer Specialist in Lucknow, Dr. N. A. Siddiqui evaluates patients with a broad range of cancers.

Breast Cancer

Breast cancer treatment is highly individualized.

Important factors may include:

  • Stage

  • Hormone receptor status

  • HER2 status

  • Tumor characteristics

  • Patient's age and health

Treatment may involve surgery, radiation, chemotherapy, hormone therapy, HER2-directed therapy, targeted treatment or immunotherapy in selected situations.

Lung Cancer

Lung cancers are broadly classified into non-small cell lung cancer and small cell lung cancer.

Treatment selection may depend on cancer type, stage, molecular alterations and immune biomarkers.

Options can include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy or combined treatment.

Oral, Mouth and Head & Neck Cancer

Persistent mouth ulcers, unexplained oral lesions, difficulty swallowing, persistent hoarseness or a neck lump should be medically evaluated.

Treatment of confirmed head and neck cancer can involve surgery, radiation therapy, chemotherapy, targeted treatments or immunotherapy depending on the diagnosis and stage.

Colon and Rectal Cancer

Colorectal cancer treatment depends on whether the cancer involves the colon or rectum and on its stage and molecular characteristics.

Treatment can include surgery, chemotherapy, targeted treatments, immunotherapy in selected biomarker-defined cancers and radiation therapy for certain rectal cancers.

Stomach, Liver, Pancreatic and Gallbladder Cancer

Gastrointestinal cancers have different treatment pathways.

Accurate staging and multidisciplinary evaluation help determine whether surgery, systemic cancer treatment or another approach is appropriate.

Prostate, Kidney and Bladder Cancer

Genitourinary cancers include prostate, kidney, bladder and testicular cancers.

Depending on the cancer, systemic treatment may involve hormone therapy, chemotherapy, immunotherapy, targeted treatment or combinations of these approaches.

Ovarian and Cervical Cancer

Gynecological cancers such as ovarian and cervical cancer may require coordinated treatment involving gynecologic surgery, systemic therapy and radiation oncology.

Medical oncology treatment may include chemotherapy, targeted therapy or immunotherapy for appropriately selected patients.

Blood Cancer

Blood cancers include:

  • Leukemia

  • Lymphoma

  • Multiple myeloma

Diagnosis may require detailed blood investigations, bone marrow examination, flow cytometry and molecular testing.

Treatment varies significantly according to the exact type and subtype of blood cancer.

Personalized Cancer Treatment

The concept of personalized cancer care means that treatment decisions are based on the characteristics of both the cancer and the individual patient.

A medical oncologist may consider:

  • Exact cancer type

  • Pathological subtype

  • Cancer stage

  • Biomarkers and molecular alterations

  • Previous treatments

  • Age

  • Performance status

  • Kidney and liver function

  • Other medical conditions

  • Expected benefits of treatment

  • Possible treatment risks

  • Patient preferences and treatment goals

Two patients with the same broad cancer diagnosis may therefore receive different treatment plans.

This is one of the reasons why cancer treatment should be planned after complete clinical evaluation rather than on the basis of a single scan or laboratory report.

Multidisciplinary Cancer Care

Many cancers require care from more than one medical specialty.

Depending on the diagnosis, Dr. N. A. Siddiqui may coordinate treatment with:

  • Surgical oncologists

  • Radiation oncologists

  • Pathologists

  • Radiologists

  • Nuclear medicine specialists

  • Gastroenterologists

  • Pulmonologists

  • Gynecologists

  • Urologists

  • Pain and palliative care specialists

  • Other relevant specialists

The order of treatment is also important.

Some patients may need surgery first and chemotherapy afterward, while others may receive medical treatment before surgery. Certain cancers may require chemotherapy and radiation together.

A coordinated approach helps determine an appropriate sequence for each patient.

Cancer Second Opinion in Lucknow

A cancer second opinion can be helpful when a patient or family wants another qualified oncologist to review the diagnosis or proposed treatment plan.

Consider seeking a second opinion when:

  • Cancer has recently been diagnosed

  • The pathology is unusual or complex

  • Several treatment options are available

  • Major cancer treatment is being planned

  • Cancer has returned after treatment

  • Cancer has progressed during treatment

  • A new chemotherapy regimen is being considered

  • Targeted therapy or immunotherapy is being considered

  • You want confirmation of an existing treatment plan

A second opinion does not necessarily mean that the first treatment recommendation was wrong.

In many cases, it may confirm the existing plan and give the patient greater confidence. In other cases, additional testing or another reasonable treatment approach may be identified.

What to Bring to Your Oncology Consultation

If you have already undergone investigations or treatment, bringing complete medical records can help the oncologist evaluate your case more efficiently.

Whenever available, carry:

  • Biopsy report

  • Histopathology report

  • Immunohistochemistry report

  • Pathology slides or blocks if review is required

  • CT scan report

  • MRI report

  • PET-CT report

  • Scan images/CDs

  • Recent blood tests

  • Molecular or biomarker test reports

  • Previous chemotherapy details

  • Radiation treatment records

  • Surgery/discharge summary

  • Current medication list

  • Details of other medical conditions

Do not worry if every document is not available. The oncologist can guide you regarding what additional information may be required.

When Should You Consult a Cancer Specialist?

You may consider consulting a Cancer Specialist in Lucknow if:

  • A biopsy has confirmed cancer

  • A scan has raised suspicion of cancer

  • You need help understanding a pathology report

  • You need cancer staging

  • Chemotherapy has been advised

  • Immunotherapy has been advised

  • Targeted therapy has been suggested

  • Cancer has returned after previous treatment

  • Cancer has spread to another organ

  • Treatment is causing significant side effects

  • You need follow-up after cancer treatment

  • You want a cancer treatment second opinion

Persistent or unexplained symptoms should also be evaluated by an appropriate medical professional rather than ignored.

Early evaluation does not mean that every symptom is cancer, but it can help identify the cause and guide further investigation where necessary.
