What is Cancer Staging Systems Overview?

Cancer staging communicates tumor extent at diagnosis and after surgery. The American Joint Committee on Cancer and the International Union Against Cancer maintain the tumor node metastasis system, which combines primary tumor characteristics, regional node involvement, and distant metastases into stage groupings from zero through four.

Disease specific systems supplement tumor node metastasis. FIGO staging governs ovarian, endometrial, cervical, and vulvar cancers, the Barcelona Clinic Liver Cancer system stages hepatocellular carcinoma, the Dukes and modified Astler Coller systems were precursors for colorectal cancer, and the Lugano system stages lymphomas. Pathologic staging is generally more accurate than clinical staging.

Staging integrates imaging, surgical findings, and pathology. Many staging schemes now include molecular features such as estrogen receptor status, microsatellite instability, or KRAS mutation that modify stage prognosis. Stage migration occurs when better imaging detects subclinical disease and changes apparent outcomes.

Symptoms

Stage zero in situ disease without symptoms
Stage one local disease often curable
Stage two extension within organ or regional nodes
Stage three locoregional advanced disease
Stage four distant metastatic disease

Risk Factors

Late presentation with advanced symptoms
Aggressive tumor biology
Inadequate initial imaging or biopsy
Limited access to molecular profiling
Tumor heterogeneity at multiple sites

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When new cancer diagnosis is made
  • When restaging is needed after recurrence
  • When imaging or pathology raises stage
  • When molecular features change risk
  • When multidisciplinary review is required

Treatment Methods

01
Comprehensive imaging including computed tomography
02
Pathologic review of surgical specimens
03
Molecular and immunohistochemical profiling
04
Tumor node metastasis stage assignment
05
Application of disease specific staging schemes

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
