Cancer Flashcards
types of cancer
carcinoma
sarcoma
leukaemia
lymphoma
central nervous system cancer
carcinoma
in skin or tissue lining internal organs
sarcoma
in bone, fat, muscle or connective tissue
leukaemia
in blood cell producing tissue
lymphoma
arise from immune system
central nervous system cancer
in brain or spinal chord
neoplasm
abnormal growth of tissue which is either benign or malignant
tumour is
a mass of tissue formed by the abnormal proliferation of cells
benign
can’t spread but can exert pressure on organs
mallignant
can invade surrounding tissue and may metastisise
how does cancer metastasis
cancerous cells divide uncontrollably leading to crowding and dysfunction or normal cells leading to organ destruction
cancer cells break off from primary tumour and enter circulatory systems and establish second tumour
risk factors of cancer
genetic
diet/ tobacco/ alcohol
diabetes and obesity
exsposure to chemicals
clinical symptoms of cancer
night sweats or fever
more tired
unexplained bleeding or bruises
unexpected pain or ache
unexplained weight loss
unusual lump or swelling
new mole
croaky voice
mouth or tongue ulcer
coughing up blood
problems peeing
blood in urine or faeces
what is cancer
caused by mutation to DNA in cells
RESULTS IN erros in normal cell growth- errors in regulation and differentiation
cancer cells
grow in absense of signalling tellimg them to grow
ignore signalls o tell them to stop dividing or growing
invade nearby areas to spread
tell blood vessels to grow towards these cells
hide in immune system
multiple changes in the cells
cancer pain
pressure, obstruction, stretching, tissue damage or inflammation
clinical manifestation Cachexia
wasting
anorexia
early satierty
weight loss
marker weakness
taste alternation
altered metablosim
anaemia in cancer
chronic bleeding
malnutrition
medical therapies
paraenroplastic syndrome in cancer
release of hormones by cancer cells
cause haematological complcations
prostate cancer
abnormal cells in prostate growth in the cells that line the prostate
risk factors of prostate cancer
genetics
genes
age
breast cancer
abnormal cells lining breast lobes
risk factors of cancer
family history/ genetic inherited// medical history- reproductive history/ dense breast
limited exercises
tobaco
alcohol
overweight
clinical maifestation of breast cancer
depends where tumour is to how big and how quick it grows
new lump
breast screening
