In this blog, we will break down how cancer specialists like Dr. Sumant Gupta diagnose and stage different types of cancer.

What Is Cancer Diagnosis?

Cancer diagnosis refers to the process of identifying whether a person has cancer, determining its type, and understanding how far it has progressed. It involves a combination of clinical examination, imaging, laboratory tests, and biopsy procedures.

Common Signs That Lead to Diagnosis

Patients are often referred to an oncologist like Dr. Sumant Gupta when they experience:

  • Persistent fatigue or weight loss

  • Unexplained pain or lumps

  • Blood in stools or urine

  • Skin changes or unhealed wounds

  • Abnormal bleeding

Once such symptoms are identified, cancer specialists begin a comprehensive diagnostic process.

Step-by-Step: How Cancer Specialists Diagnose Cancer

1. Initial Consultation and Medical History

The process begins with a detailed consultation where the doctor:

  • Reviews the patient’s personal and family medical history

  • Evaluates symptoms

  • Performs a physical examination

2. Diagnostic Imaging

To visualize abnormal growths, oncologists recommend imaging tests, including:

  • CT Scan: Gives a detailed cross-sectional image of internal organs

  • MRI: Useful for detecting tumors in soft tissues and the brain

  • Ultrasound: Non-invasive tool for initial tumor detection

  • PET Scan: Shows the metabolic activity of cells—often used to detect cancer spread

3. Blood and Laboratory Tests

Blood tests can reveal tumor markers or abnormal cell counts:

  • Complete Blood Count (CBC): Detects abnormalities in red/white blood cells

  • Tumor Markers: Substances like PSA, CA-125, AFP, etc.

  • Liver and Kidney Function Tests: Assess body’s ability to tolerate treatment

4. Biopsy – The Gold Standard

A biopsy involves removing a small tissue sample to be examined under a microscope:

  • Needle Biopsy

  • Endoscopic Biopsy

  • Surgical Biopsy

Dr. Sumant Gupta ensures that biopsies are guided by imaging to maximize accuracy and minimize discomfort for the patient.

What Is Cancer Staging?

After diagnosis, staging is done to determine how much cancer is present and whether it has spread. Cancer staging helps:

  • Decide the best treatment plan

  • Predict prognosis

  • Monitor treatment response

The TNM System Explained

Most oncologists, including Dr. Sumant Gupta, use the TNM staging system:

  • T (Tumor): Size and extent of the main tumor

  • N (Nodes): Spread to nearby lymph nodes

  • M (Metastasis): Presence of cancer in distant organs

Staging Categories

  • Stage 0: Carcinoma in situ (early form)

  • Stage I: Localized cancer

  • Stage II & III: Regional spread to lymph nodes or nearby tissues

  • Stage IV: Distant spread (metastasis)

Role of a Cancer Specialist in the Diagnosis & Staging Process

Cancer specialists like Dr. Sumant Gupta play a pivotal role by:

  • Coordinating with radiologists, pathologists, and surgeons

  • Choosing the most appropriate diagnostic tools

  • Interpreting biopsy and imaging results

  • Recommending further genetic or molecular testing if needed

  • Using staging information to personalize treatment

Dr. Sumant Gupta believes in a patient-centric approach, ensuring that patients and their families understand every step of the process, thus reducing anxiety and improving outcomes.

Why Accurate Diagnosis and Staging Matter

  • Tailored Treatment Plans: Treatment like chemotherapy, radiation, or surgery depends on stage and cancer type

  • Avoids Over/Under Treatment: Prevents unnecessary therapies or delays

  • Improves Survival Rate: Early detection and accurate staging increase the chances of remission

  • Enables Clinical Trials: Some patients may benefit from advanced treatment protocols available only through clinical trials
