Cancer MCQ Quiz

Cancer MCQ Question and Answer

• Prostate cancer is the most common cancer in men.

Key Characteristics of Cancer

• Uncontrolled cell growth and proliferation are hallmarks of cancer.
• Malignant tumors form, invading surrounding tissues and spreading (metastasis).
• Cancer cells have altered cellular processes, including disruptive genetic mutations.
• Key features include abnormal growth, immune evasion, angiogenesis promotion, invasion & metastasis, immortalization, growth suppressor avoidance, sustained angiogenesis, resistance to cell death, and cellular energetic deregulation.
• Cancer development is a multi-step process involving genetic mutations and environmental exposures.

Cancer Types

• Cancers affect various body parts, resulting in diverse types.
• Common cancers include lung, breast, colon, prostate, and leukemia.
• Each cancer type has unique characteristics, symptoms, and treatment approaches.
• Age, lifestyle, genetics, and environmental exposures influence cancer risk.

Cancer Risk Factors

• Genetic predisposition (family history, inherited mutations) increases cancer risk.
• Smoking, poor diet, lack of activity, and excessive alcohol are major lifestyle risk factors.
• Carcinogens (chemicals, radiation) increase cancer risk from environmental exposures.
• Aging increases cancer risk.
• Certain viruses, bacteria, and parasites increase cancer risk.
• Chronic inflammation creates an environment conducive to cancer.
• Obesity is linked to higher cancer risk.

Cancer Detection and Diagnosis

• Early cancer detection is vital for effective treatment and better survival rates.
• Screening tests (mammograms, colonoscopies) aid early detection.
• Symptoms include unusual lumps, bowel/bladder changes, persistent coughs, unexplained weight loss, unusual bleeding, or discharge.
• Diagnosis involves imaging (X-rays, CT, MRI), biopsies, and blood tests.

Cancer Treatment

• Cancer treatment aims to eliminate/control cancer cells while minimizing damage to healthy tissue.
• Treatments include surgery, radiation, chemotherapy, targeted therapy, hormone therapy, and immunotherapy.
• Treatment decisions are tailored to cancer type/stage, patient health, and preferences.
• Palliative care manages symptoms and improves patient quality of life.

Cancer Prognosis and Survival

• Prognosis and survival depend on cancer type/stage, overall patient health, and treatment effectiveness.
• Ongoing research improves treatment methods and outcomes.
• Early detection, diagnosis, and treatment advancements improve survival.
• Prognosis factors include tumor characteristics (grade, stage), patient characteristics (age, health), and treatment type.

Cancer Prevention

• Lifestyle modification plays a key role in cancer prevention.
• Healthy diet, regular exercise, and tobacco avoidance decrease cancer risk.
• Regular check-ups and cancer screenings are essential for early detection.
• Vaccinations against cancer-linked viruses (e.g., HPV) reduce risk.
• Prevention strategies target modifiable risk factors.

Cancer Progression

• Cancer progression involves steps from initial genetic damage to clinically detectable tumors.
• Malignant tumors invade surrounding tissues and spread (bloodstream/lymphatics).
• Cancer progression rates and patterns vary between types.
• Progression involves genetic mutations, tumor microenvironment, and the patient's immune system.
