"A neoplasm is a type of abnormal and excessive growth of tissue."
Explains the process of abnormal growth and differentiation, leading to the formation of tumors. Covers the different types of tumors, their characteristics, and the factors that influence their growth and spread.
Cell proliferation: The process of cell division and replication that leads to neoplastic growth.
Tumor classification: The categorization of tumors based on their histological and morphological characteristics.
Tumor grading: The evaluation of tumors based on the degree of differentiation and the level of abnormality of the cells in the tumor.
Oncogenes and tumor suppressor genes: The molecular basis of neoplastic growth and how mutations in genes can lead to the formation of tumors.
Molecular markers of neoplasia: The identification of specific molecules that are expressed differently in neoplastic cells than in normal cells, and how these markers can be used to diagnose and treat neoplasms.
Carcinogenesis: The process of tumor formation, including the initiation, promotion, and progression of neoplastic growth.
Diagnosis of neoplasia: How to detect the presence of neoplasms using various diagnostic modalities, including imaging, biopsy, and laboratory tests.
Staging of neoplasia: The evaluation of the extent of neoplastic growth and metastasis to determine appropriate treatment options.
Treatment of neoplasia: The different treatment options available for neoplasms, including surgery, chemotherapy, radiation therapy, and immunotherapy.
Prognosis: The prediction of the likely outcome of neoplastic growth based on various factors, including tumor type and stage, age, and overall health status.
Carcinoma: These are cancerous tumors that form from epithelial cells, which are located in the lining of various organs throughout the body. They are the most common type of cancer, accounting for over 80% of all cases.
Sarcoma: Sarcomas are tumors that develop in the body's connective tissues, such as bones, cartilage, and muscles. They are less common than carcinomas and are generally more difficult to treat.
Lymphoma: Lymphomas are cancers that originate in the lymphatic system, which is responsible for maintaining the body's immune system. They can affect the lymph nodes, spleen, and other organs.
Leukemia: Leukemia is a type of cancer that affects the blood and bone marrow. It arises from abnormal white blood cells that overproduce and accumulate in various parts of the body.
Melanoma: Melanoma is a type of skin cancer that develops from melanocytes, which are the cells responsible for producing skin pigmentation. It is one of the more aggressive and deadly types of cancer.
Neuroblastoma: Neuroblastomas are rare tumors that typically develop in young children. They arise from the nerve tissue that forms the sympathetic nervous system, which controls the body's fight-or-flight response.
Glioma: Gliomas are tumors that form in the brain, spinal cord, and other parts of the central nervous system. They are often difficult to treat and can vary in severity depending on their location.
Hepatocellular carcinoma: Hepatocellular carcinoma is a type of liver cancer that typically affects individuals with chronic liver disease. It arises from the liver cells (hepatocytes) themselves and is often associated with risk factors such as viral hepatitis, obesity, and alcohol consumption.
"The process that occurs to form or produce a neoplasm is called neoplasia."
"The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue."
"Yes, the neoplasm persists in growing abnormally, even if the original trigger is removed."
"When a neoplasm forms a mass, it may be called a tumor or tumour."
"The ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior."
"Malignant neoplasms, which are cancers, are the focus of oncology."
"Prior to the abnormal growth of tissue, cells often undergo an abnormal pattern of growth, such as metaplasia or dysplasia."
"No, metaplasia or dysplasia does not always progress to neoplasia and can occur in other conditions as well."
"The word neoplasm is from Ancient Greek νέος- neo 'new' and πλάσμα plasma 'formation, creation'."
"The Greek term 'neo' in neoplasm means 'new'."
"The Greek term 'plasma' in neoplasm means 'formation, creation'."
