What is Cancer Prevention?

Cancer prevention encompasses all strategies aimed at reducing the risk of developing cancer. According to the World Health Organization, an estimated 30-50% of cancer cases can be prevented through avoidable behaviors and modifiable risk factors. Prevention involves both individual choices (diet, exercise, avoiding tobacco) and population-level efforts (vaccination, screening programs, environmental policies).

Primary prevention focuses on stopping cancer before it begins by avoiding carcinogens, getting vaccinated against cancer-linked viruses (HPV, hepatitis B), and maintaining a healthy lifestyle. Secondary prevention involves early detection through screening (mammography, colonoscopy, Pap smears) so cancer can be caught at curable stages.

Smoking cessation is the most impactful single intervention — tobacco causes about 22% of all cancer deaths globally. Other important prevention pillars include weight management, regular physical activity, limiting alcohol, sun protection, and avoiding occupational carcinogens. Each step compounds risk reduction over a lifetime.

Symptoms

No symptoms — prevention is about reducing future risk, not treating disease
Persistent cough or hoarseness (early warning, not prevention)
Unexplained weight loss (warrants evaluation)
Changes in moles or skin lesions (skin cancer screening)
Persistent indigestion or swallowing difficulty
Unusual bleeding (rectal, vaginal, urinary)
Lumps or thickening in any tissue
Persistent fatigue without obvious cause

Risk Factors

Tobacco use (smoking, chewing, secondhand exposure)
Obesity and physical inactivity
Excessive alcohol consumption
Unhealthy diet (high in processed meat, low in fiber/vegetables)
Ultraviolet radiation exposure (sun, tanning beds)
Chronic infections (HPV, hepatitis B/C, H. pylori, EBV)
Occupational carcinogens (asbestos, benzene, certain chemicals)
Family history and inherited genetic mutations (BRCA1/2, Lynch)

When to See a Doctor?

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

  • Regular check-ups and age-appropriate cancer screening (mammography, colonoscopy, Pap smear, low-dose CT for smokers)
  • Smoking cessation counseling and support programs
  • Genetic counseling if strong family history of cancer
  • Vaccination consultations (HPV, hepatitis B)
  • Skin examinations for high-risk individuals (fair skin, multiple moles, family history)
  • Nutritional consultation for weight management and dietary improvement
  • Occupational health evaluation if exposed to known carcinogens
  • New, persistent, or worsening symptoms — early evaluation saves lives

Treatment Methods

01
Smoking cessation: counseling, nicotine replacement, varenicline, bupropion
02
Vaccination: HPV (cervical, oropharyngeal, anal cancers), hepatitis B (liver cancer)
03
Cancer screening: mammography, colonoscopy, Pap smear/HPV test, low-dose CT, PSA (selective)
04
Chemoprevention: tamoxifen/raloxifene (high-risk breast), aspirin (selective colorectal)
05
Risk-reducing surgery: prophylactic mastectomy/oophorectomy in BRCA carriers
06
Lifestyle modification: balanced diet, regular exercise, weight management, alcohol moderation
07
Sun protection: SPF 30+, protective clothing, avoid tanning beds
08
Eradication of chronic infections: H. pylori treatment, hepatitis B/C antiviral therapy

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.
