Answer
Cancer Detection and Treatment
1. Diagnosis of Cancer
Cancers of internal organs can be detected using advanced imaging techniques:
- Computed Tomography (CT): Combines X-rays and computer technology to create detailed cross-sectional images of the body.
- Magnetic Resonance Imaging (MRI): Uses strong magnetic fields and radio waves to produce detailed images of internal organs and tissues.
2. Chemotherapy
Chemotherapeutic drugs are used to kill or inhibit the growth of cancerous cells. These drugs are especially effective against rapidly dividing cells, making them a key component in cancer treatment.
3. Immunotherapy
Patients are often given substances known as biological response modifiers, which enhance the body’s immune system. One such substance is α-interferon, a protein that activates the immune system to recognize and destroy tumor cells.
4. Leukemia
Leukemia is a type of cancer that affects the blood and bone marrow. It is characterized by a significant increase in the number of abnormal white blood cells.
This comprehensive approach—combining early detection, chemotherapy, and immunotherapy—helps improve cancer treatment outcomes.
