Sarcoma (connective/ soft tissue: bone, muscle, fat)

Melanoma (pigment cells) 

Brain tumors (glioma) 

burden of cancer in CH (number)

Men and Woman (prevalence)

1. Prostate, Lung, Colorectal

2. Breast, Colorectal, Lung 

Burden WW (new and deaths) 

 

18.1 mio new cases

9.6 mio cancer deaths 

 

Caner dangerous 

local effects

 

local damage to tissue

obsturction (GIT, blood vessel)

bleeding pressure and mass effects 

Cancer dangrous

systemic (6)

Bllod clots

infection

cachexia (weight lose, weakness and fatigues = wasting syndrome) 

metastasis

iatrogenic (complications of treatment and diagnosis) 

metastasis 

what is this_ 

along_

casuses problems at metastasis site: _ (4)

spread of cancer to other body parts

along lymphatic cessels or blood stream 

bone, liver, lung, brain 

Cancer RF (a lot) 

age, amoking, alcohol, obesity, diet, PA, carcinogenic substances, radiation, sunlight, infectious agents, immunosuppresion, genetics 

RF Cancer-causing substances

2x

Examples (2.)

 

environmental or occupational

ex: toxins, coal smoke, asbestos, benzol, wood dust 

RF radiation and sunlight

radiation (occupational, other RF) 

Sunlight 

radiology and radiation workers, medical examinations, flight traffic, radon gas, normal background radiation 

Sunlight: UV light 

Hepatitis B/C leads to

HIV leads to 

Transplant patients leads to (4)

HIV: AIDS associated cancers

Transplant: skin, lung, liver, kidney cancer

Genetics RF of cancer

familial and hereditary cancers 

EX (3) 

 

born with vertain changes or mutations in genes

higher probability of developing cancer

5-10% cancer 

Ex: BRCA1/2: breast & ovarian cancer/ APC gene: colorectal cancer/ TP53: breast cancer, sarcoma, brain tumors, leukemia

how can cancer be prevented (6)

healthy lifestyle (safe sex), exposure prtection adn reduction, vaccination, treatment of infectious diseases, screening, prophylactic surgery (AJ) 

when should we screen (5)

condition of PH relevance

treatable

better prognosis with eraly treatment

good test avialable

low impact, simple, time-efficient, ressource-efficient, whtical 

Screening
