- most important feature of benign tumours
- remains localized
- inflammation
- The nonspecific immune response that occurs in reaction to any type of bodily injury
- benign tumours relationship to surrounding tissue
- applies pressure, compresses
- chronic inflammation is characterized by
- macrophages, lymphocytes and proliferation of connective tissue fibroblasts
- accommodation of cancers to a group relating to the spinal cord and nervous system
- neuroectoderm
- histology
- The study of tissues and cells under a microscope.
- chronic inflammation
- a persistent inflammation that can lead tissue change, longer duration where more tissue is destroyed, little change in symptoms
- malignant tumours rate of growth
- rapidly
- accommodation of cancers to a group relating to the embryonic tissue
- mesenchymal
- accommodation of cancers to a group relating to the blood formation
- haemopoietic and lymphoid cells
- palliative care
- any form of medical care that concentrates on reducing the severity of the symptoms oppose to trying to cure the disease
- accommodation of cancers to a group relating to the skin
- epithelia
- signs of chronic inflammation
- tissue destruction, scar tissue, loss of function, swelling, pain
- proliferation
- Rapid reproduction, multiplication or growth in numbers and of tissue production
- tumour
- An abnormal mass of tissue that results when cells divide more than they should or do not die when they should
- most important feature of malignant tumours
- cells transfer and infiltrate via lymphatics and blood vessels, spreading everywhere
- benign tumours rate of growth
- slowly
- malignant relationship to surrounding tissue
- invades and destroys it
- two main groups of tumours
- benign and malignant
- symptoms of acute inflammation
- fever, chills, fatigue, headaches, loss of appetite, muscle stiffness
- signs of acute inflammation( and reasons)
- redness+heat(increased blood flow), pain(local irritation and pressure on nerves), swelling(edema), loss of function(nutrient deficiency)
- symptoms of chronic inflammation
- lack of sleep, low adrenal functions. change of cells, damage and death to cells.
- boundaries of malignant tumours
- irregular, ill-defined and non-encapsulated
- acute inflammation
- a short and sudden response that is normally visual and is associated with neutrophils
