Study Notes

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.
