5. Cancer Symptoms and Side Effects

• Cachexia: Severe weight loss and muscle wasting associated with advanced cancer.
• Paraneoplastic Syndromes: Symptoms caused by substances produced by the tumor, not the tumor’s physical presence.
• Neutropenia: A low level of neutrophils, increasing infection risk, often caused by chemotherapy.
• Alopecia: Hair loss, a common side effect of chemotherapy.

6. Monitoring and Prognosis

• Recurrence: Return of cancer after treatment and a period of remission.
• Remission: Reduction or disappearance of signs of cancer; can be partial or complete.
• Survival Rate: Percentage of people who survive a certain type of cancer for a specified period.
• Progression-Free Survival (PFS): Time during and after treatment in which the disease does not worsen.

Molecular and Genetic Terms

• Oncogene: A gene that has the potential to cause cancer when mutated or overexpressed.
• Tumor Suppressor Gene: A gene that prevents uncontrolled cell growth; mutations inactivate its function (e.g., TP53).
• Biomarker: A measurable substance in the body indicating the presence or behavior of cancer (e.g., PSA for prostate cancer).
• Driver Mutations: Genetic changes that contribute directly to cancer progression.

+ Treatment Modalities

• Chemotherapy: Use of drugs to destroy cancer cells or slow their growth.
• Radiation Therapy: Use of high-energy radiation to kill or damage cancer cells.
• Immunotherapy: Boosting the immune system to recognize and destroy cancer cells.
• Targeted Therapy: Drugs that target specific molecules involved in cancer growth.
• Surgery: Physical removal of the tumor and sometimes surrounding tissues.
• Hormone Therapy: Blocking hormones that fuel certain cancers (e.g., breast or prostate cancer).

+ Diagnosis and Staging

• Biopsy: Removal of a sample of tissue for microscopic examination to diagnose cancer.
• Imaging Studies: Techniques like CT, MRI, PET scans, and X-rays used to visualize tumors.
• TNM Staging: A system to describe cancer stages:
• T (Tumor): Size and extent of the primary tumor.
• N (Node): Spread to nearby lymph nodes.
• M (Metastasis): Spread to distant organs.
• Grade: A measure of how much cancer cells differ from normal cells, indicating aggressiveness.

In oncology, precise terminology is essential for understanding, diagnosing, and treating cancer. Below is an overview of common terms and concepts used in the field:

+ General Cancer Terms

• Oncology: The branch of medicine dealing with the prevention, diagnosis, and treatment of cancer.
• Tumor (Neoplasm): An abnormal growth of cells that can be benign (non-cancerous) or malignant (cancerous).
• Carcinoma: A cancer that begins in the epithelial cells lining the skin or internal organs.
• Sarcoma: Cancer originating in bone, cartilage, fat, muscle, or connective tissue.
• Lymphoma: Cancer of the lymphatic system.
• Leukemia: Cancer of the blood-forming tissues, like the bone marrow.
• Metastasis: Spread of cancer cells from the primary tumor to other parts of the body.
