yes and no
u kno tat of ppl tat turn up to medical practitioners for examination after they felt a lump.. tat only 20% are a tumour but half of them are cancers.. its the technique.. its hard to get right and educate a person tat there isnt a general case .. but with any lumps u shoud get it checked.. and if the cancer can be felt its quiet big already
it why u need a mammogram if ure a woman over 50.
science is awesome in med if u enjoy it.. cos they kno tat u did it.. so they usualli dun assess it very well.. and its contextual and continuous..
we do very lil maths.. till later and it is all stats.. im not sure but wats it like in chiro?
