Study Notes
Oncology
- The science of the study of neoplasms is called oncology.
Neoplasms
- An abnormal new growth that is causeless, aimless, and without limitations is called a neoplasm.
- A malignant neoplasm is also known as cancer.
Types of Cancer
- The increased incidence of stomach cancer in Japan is associated with diet.
- The increased incidence of lung cancer in Egypt is linked to bilharziasis.
Tissue Classification
- Connective tissue is not classified under epithelial tissue.
Benign and Malignant Neoplasms
- The main difference between benign and malignant neoplasms is that malignant neoplasms can invade and metastasize to other parts of the body.
- Malignant tumors can metastasize through the lymphatic system, bloodstream, or directly infiltrate surrounding tissues.
Cancer Classification
- Grading is a method of cancer classification that evaluates the degree of abnormality of cancer cells.
- The main purpose of grading is to provide information about the prognosis and treatment of the cancer.
Microscopic Criteria
- Microscopic criteria that indicate malignancy include anaplasia, loss of differentiation, and presence of abnormal mitotic figures.
- Anaplasia refers to the loss of normal cellular differentiation and function.
Complications
- A possible complication of benign tumors is compression of surrounding tissues.
- The main cause of death in cancer is metastasis to vital organs.
Metastasis
- Lymphatic spread refers to the spread of cancer cells through the lymphatic system.
Viral Associations
- Hepatitis B virus is linked to hepatocellular carcinoma.
Age and Cancer
- Cancer is more common in older adults, with the incidence increasing with age.
