What is Bladder Cancer?

Bladder cancer is most often urothelial carcinoma arising from the bladder mucosa; squamous and adenocarcinoma variants also occur.

Non-muscle-invasive (NMIBC) includes Ta, T1, and carcinoma in situ (CIS); muscle-invasive (MIBC) is T2-T4.

Diagnosis combines cystoscopy with biopsy/resection (TURBT), urine cytology, and CT urography for upper-tract evaluation.

Risk stratification uses grade, stage, size, number, CIS, and recurrence pattern to guide intravesical therapy and surveillance.

Symptoms

Painless gross or microscopic hematuria (most common presentation)

Urinary frequency, urgency, and dysuria

Suprapubic or pelvic pain

Recurrent urinary tract infections

Flank pain from ureteral obstruction

Weight loss, fatigue, or bone pain in advanced disease

Risk Factors

Tobacco smoking (the most important modifiable risk factor)

Occupational exposure to aromatic amines (dyes, paints, rubber, leather)

Chronic inflammation (indwelling catheter, schistosomiasis, stones)

Pelvic radiation and cyclophosphamide therapy

Age over 55 and male sex

Family history and Lynch syndrome

When to See a Doctor?

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

Any episode of gross hematuria (requires full urologic evaluation)
Persistent microscopic hematuria or irritative LUTS without infection
Unexplained weight loss or flank pain with urinary symptoms

Treatment Methods

Transurethral resection of bladder tumor (TURBT) for diagnosis, staging, and initial treatment

Single immediate post-TURBT intravesical chemotherapy for low/intermediate-risk disease

Intravesical BCG induction and maintenance for high-risk NMIBC and CIS

Radical cystectomy with pelvic lymphadenectomy and urinary diversion for MIBC or BCG-refractory high-risk disease

Trimodal therapy (maximal TURBT + chemoradiation) as bladder-preserving option in selected MIBC

Systemic cisplatin-based chemotherapy, immune checkpoint inhibitors, and antibody-drug conjugates in advanced disease

Bladder Cancer (Comprehensive)

Onkoloji

Bladder cancer is staged from non-muscle-invasive to metastatic; treatment uses TURBT, intravesical therapy, radical cystectomy, immunotherapy, and targeted agents based on stage.

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.
