The study of the biology of cancer and the development of strategies for its prevention and treatment.
Cell signaling: Cell signaling refers to the process of communication between cells. Understanding the various signaling pathways involved in cancer development is crucial in cancer biology.
Genetics: Genetics refers to the study of genes and DNA. Cancer is often caused by genetic mutations, and studying genetics helps in understanding the genetic basis of cancer development.
Epigenetics: Epigenetics refers to changes in gene expression without affecting the underlying DNA sequence. It plays a major role in cancer development as many cancer cells have altered epigenetic regulations.
Cell cycle and apoptosis: The cell cycle is a series of events that cells go through to divide and grow. Apoptosis is the natural process of programmed cell death. Understanding the complex mechanisms that regulate these processes is essential in cancer biology.
Oncogenes and tumor suppressor genes: Oncogenes are genes that promote cell growth and division, while tumor suppressor genes are genes that inhibit cell growth and division. Mutations in these genes are often found in cancer cells.
DNA damage and repair: DNA damage occurs frequently in cells due to various internal and external factors. Understanding the mechanisms that repair DNA damage is crucial in cancer biology as cancer cells often have defective DNA repair mechanisms.
Angiogenesis: Angiogenesis refers to the process of new blood vessel formation. It plays a crucial role in tumor growth as tumors need a blood supply to grow beyond a certain size.
Metastasis: Metastasis is the process by which cancer cells spread from the original site to other parts of the body. It is a complex process that involves various signaling pathways and mechanisms.
Immunology and cancer: The immune system plays a crucial role in detecting and eliminating cancer cells. Understanding the complex interaction between cancer cells and the immune system is essential in developing effective cancer therapies.
Cancer stem cells: Cancer stem cells are a small population of cells within a tumor that have stem cell-like properties. They are thought to be responsible for tumor initiation, growth, and resistance to therapy.
Drug discovery and development: Developing effective cancer therapies is a major challenge in cancer biology. Understanding the mechanisms of drug action and resistance, as well as the process of drug development, is crucial in developing new cancer therapies.
Clinical trials: Clinical trials are essential in evaluating the safety and efficacy of new cancer therapies. Understanding the design, conduct, and analysis of clinical trials is necessary in cancer biology.
Ethics and cancer research: Cancer research involves human subjects, and ethical considerations are crucial in conducting research involving human subjects. Understanding the ethical principles and guidelines in cancer research is essential for cancer biology researchers.
Public health and cancer: Cancer is a major public health concern, and understanding the epidemiology, prevention, and early detection of cancer is crucial in addressing this global health challenge.
Carcinomas: These are cancers that develop from epithelial cells, which are found in tissues that line the surfaces of organs and various other structures throughout the body.
Sarcomas: These are cancers that arise from connective tissues such as bone, cartilage, fat, and muscle.
Lymphomas: These are cancers developed in the lymphatic system, which is responsible for fighting infections and regulating fluids in the body.
Leukemias: These are cancers of the blood-forming tissues that impact blood and bone marrow.
Melanomas: These are cancers that develop in pigment-containing cells known as melanocytes, typically found in the skin.
Neuroblastomas: These cancers start from immature nerve cells found in various parts of the body, especially in infants and young children.
Gliomas: These are the most common type of primary brain tumor, arising from the glial cells that support neurons.
Hepatocellular carcinomas: These are cancers that develop from the liver cells, and they are known to be associated with viral hepatitis B and C infections.
Breast cancer: This is one of the most common types of cancer that develops in the breast tissue.
Prostate cancer: This is the most common cancer among men, and it develops from the prostate gland.
