What is Cancer Screening: Guideline Summary?

Cancer screening looks for malignancy or precancer in asymptomatic people. Effective programs require accurate tests, an actionable lesion (precancer or early cancer), and an intervention that improves outcome. Screening is not appropriate for every cancer; for many tumors no test improves survival.

Major guideline-supported screening programs are: mammography for breast cancer (typically biennial from age 40 to 74); HPV testing or co-testing every 5 years from age 25 to 65 for cervical cancer; colonoscopy every 10 years (or stool-based testing more frequently) from age 45 to 75 for colorectal cancer; low-dose CT annually from age 50 to 80 for current or former heavy smokers for lung cancer; and shared decision making about PSA testing for prostate cancer between ages 55 and 69.

Screening should be tailored to life expectancy and individual risk. People with strong family history, hereditary syndromes (BRCA, Lynch, FAP, Li-Fraumeni), prior radiation, or inflammatory bowel disease may need earlier and more intensive screening. Stopping screening at older ages or with limited life expectancy avoids over-diagnosis and harm.

Symptoms

Most early cancers are asymptomatic — the goal of screening
New breast lump, nipple discharge, skin change
Postcoital or postmenopausal bleeding
Rectal bleeding, change in bowel habit, weight loss
Persistent cough or hemoptysis
Urinary changes or new pelvic pain

Risk Factors

Family history of cancer in first-degree relatives
Known hereditary cancer syndrome
Tobacco use, especially heavy smoking
Chronic infections (HPV, HBV, HCV, H. pylori)
Prior therapeutic radiation

When to See a Doctor?

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

  • When age- and sex-appropriate screening becomes due
  • Strong family history of cancer for genetic counseling
  • New symptoms suggesting possible cancer
  • Confusion about whether to continue screening at older ages

Treatment Methods

01
Mammography every two years age 40 to 74
02
HPV testing or co-testing every five years age 25 to 65
03
Colonoscopy every ten years (or FIT yearly) age 45 to 75
04
Annual low-dose CT for high-risk smokers age 50 to 80
05
Shared decision making for PSA age 55 to 69
06
Hereditary cancer syndrome assessment when indicated
07
Individualize stopping age by life expectancy and comorbidity

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.
