Chance mom might have cancer?

See just 1 or 2 symptoms are not enough to diagnosis or can detect any thing about disease , How many moles she has ? , How old is she ? Is her periods stoped that means is she under menupause period ?Do u have any genetic history of having anytype of cancer? Does she has any kind of other health problems? Does she takes any kind of drugs or do smoking ? because all these thing may help to find the cause of cancer , particular cancer .Do not worry , just wait and watch and if u find anything abnormal that is enlargement in size of mole , any redness arround the mole , any discharge and pain in moles than u must go to doctor , other wise if u do not find any change in them for long time than its nothing . Okay . All the best .

Parts of moles do not fall off without injury and neither do cancerous ones.

The only way to find is to see a dermatologist

yes, quite common, but i get skin checks every year
