Description

Psychology, Oncology, the branch of medicine provided to the study and treatment of cancer, plays an essential role in addressing the human significant health challenges. Cancer, characterized by the uncontrolled growth and spread of abnormal cells, has a major impact on individuals, families and societies worldwide. Cancer develops from genetic mutations and changes in cellular behavior that affect normal cell growth and division. These mutations can be caused by various factors, including environmental exposures, lifestyle choices, infections and hereditary predisposition. The field of oncology aims to understand these mechanisms to develop effective techniques for prevention and treatment.

Types of cancer

Cancers are categorized based on their origin and cell type. The major types include.

Carcinomas: Originating in epithelial cells, these are the most common cancers, including breast, lung, colon and prostate cancers.

Sarcomas: Developing of connecting tissues such as muscular tissue, bone and osteoarthritis.

Leukemias: Affects the blood and bone marrow, causing abnormal white blood cell production.

Lymphomas: Originating in the lymphatic system.

Brain and spinal cord tumors: Tumors of the central nervous system include gliomas and meningiomas.

Each cancer type has unique characteristics that influence its progression and treatment.

Prevention and risk reduction

Preventive oncology focuses on minimizing cancer risk through lifestyle modifications, early detection and public health initiatives. Significant preventive methods include: Smoking is a leading cause of lung and other cancers. Public health causes and cessation programs significantly reduce risk. A balanced diet rich in fruits, vegetables and whole grains, combined with regular physical activity, reduces the risk of various cancers. Vaccines including the Human Papillomavirus vaccine (HPV) and hepatitis B vaccine prevent cancers associated with viral infections. Early detection through mammograms and colonoscopies enables immediate intervention and improves outcomes.

Diagnosis and staging

Accurate diagnosis is essential for effective treatment planning. Diagnostic technologies such as X-rays, Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans provide detailed images of malignancies. Tissue samples are analyzed to confirm cancer type and grade. Identifies genetic mutations and biomarkers that guide targeted therapies. Cancer staging determines the extent of disease spread, categorized from Stage 0 (localized) to Stage IV (metastatic). Staging guides treatment decisions and prognosis.

Treatment modalities

Oncology treatments aim to prevent cancer, prevent recurrence or manage symptoms. Common modalities include: Surgical oncology involves removing tumors and surrounding tissue. Advances in minimally invasive techniques and robotic surgery have improved precision and recovery times. Radiation therapy employs high-energy beams to eliminate cancer cells. Techniques including Intensity-Modulated Radiation Therapy (IMRT) and stereotactic radiosurgery enhance targeting while sparing healthy tissue.

Chemotherapy employs drugs to remove immediately developing tumor cells. Although effective, it frequently causes side effects due to its impact on normal cells. Targeted drugs inhibit specific molecules involved in cancer growth. Examples include tyrosine kinase inhibitors and monoclonal antibodies, which provide precision with fewer side effects. Immunotherapy helps the body's immune system to identify and cure malignancies. Checkpoint inhibitors, Chimeric Antigen Receptor (CAR) T-cell therapy and cancer vaccines represent significant breakthroughs. Used for hormone-sensitive cancers such as breast and prostate cancer, this therapy blocks hormone production or action to slow tumor growth. For advanced cancers, palliative oncology focuses on symptom management and improving quality of life. It addresses pain, fatigue, emotional distress and other challenges.

Role of multidisciplinary teams

Oncology care requires collaboration among various specialists, including.

Medical oncologists: Manage all systemic therapies, including chemotherapy and targeted treatments.

Radiation oncologists: Design and deliver radiation therapy plans.

Surgical oncologists: Perform tumor resections and related procedures.

Pathologists: Provide essential diagnostic information through tissue analysis.

Radiologists: Interpret imaging studies for diagnosis and treatment planning.

Nurses and allied health professionals: Deliver supportive care, education and rehabilitation.
