What is Cancer Metastasis Biology?

Metastasis is the process by which cancer cells spread from a primary tumor to distant organs and form secondary tumors. It involves a metastatic cascade including local invasion, intravasation into vessels, survival in circulation, extravasation, and adaptation to a foreign microenvironment.

Mechanisms include epithelial-mesenchymal transition, stromal interactions, angiogenesis, immune evasion, and organ-specific seeding (the 'seed and soil' hypothesis). Genomic and epigenomic changes, microenvironmental factors, and circulating tumor cells contribute to metastatic competence.

Most cancer-related deaths are due to metastatic disease. Therapies target tumor-cell dependencies, the microenvironment, immune evasion, and organ-specific homing. Research areas include circulating tumor cells, dormant cells, organotropism, and tumor heterogeneity.

Symptoms

Site-specific symptoms reflecting metastatic location
Bone pain or fractures from skeletal metastases
Cough or dyspnea from pulmonary metastases
Headache or neurological deficits from brain metastases
Constitutional symptoms (weight loss, fatigue)

Risk Factors

Advanced primary tumor with high invasive potential
Specific molecular features (MET, EMT signatures)
Lymphovascular invasion at primary site
Specific tumor-organ tropism patterns

When to See a Doctor?

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

  • New focal pain, swelling, or neurological symptoms in cancer patients
  • Constitutional symptoms during follow-up
  • Imaging findings suggestive of metastasis
  • Rising tumor markers in surveillance

Treatment Methods

01
Systemic therapy targeting tumor-cell dependencies
02
Targeted therapy and immune checkpoint inhibitors
03
Local therapy for oligometastatic disease (surgery, SBRT)
04
Bone-modifying agents for skeletal metastases
05
Stereotactic radiosurgery for limited brain metastases
06
Multidisciplinary care including supportive measures
07
Clinical trials targeting metastasis biology

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.
