Is the mole raised or flat? (Raised is not usually cancer.) Regarding your bones, are you getting a calcium supplement every day? If you are not, getting enough, your bones can actually ache. Regarding your mom's cervical cancer, did she get it from having hpv? (If you get the hpv vaccine, you will not get it hpv, and besides, there is nothing genetic about getting cervical cancer from an acquired virus.) Look up each cancer you're worried about, and get some facts. It helps A LOT.
Rather than ring up the doc and say "Hey, man, test me for everything, I'm sure I'm seriously ill with cancer" ask instead to go in soon for a general check-up. Your family can't say much about that, you should have one every year or two. (If you have to, tell your mother that your periods are acting funny. That should do it.) Then kick everyone out and tell the doctor that you are very anxious about particularly breast, cervical and skin cancer because various members of the family have had these. The doctor will ask you for the closeness of the relationship (my doc yawned when I told him my aunt had had breast cancer after menopause, for example, but if it had been my mother and before menopause, he would have sat up and taken notes). Anyway, the wording of it as you feeling anxious over these things is true -- you certainly don't know you have cancer, but you obviously feel anxious after watching a loved one suffer, and maybe the doctor will have some wise words about the chances and the odds, and also a plan for how often to get checked, that will help you feel a bit more in control. Please remember that no cancer just appears one day and the next day you are very sick or die. You can get your skin or your cervix checked yearly, for example, as a standard practice.
Take care, it does sound more like anxiety than illness, but there is no reason not to go get a checkup and open the topic of anxiety. Lots of people come to see the doc because they're worried they will get a disease they have seen others in the family have to cope with. It will help to talk it over.
Which is the intensity of the pain? It is worse at night? Has been spreading red,white or blue pigmentation to surrounding of the mole?
Well you probably just think you are having these pains and such but better safe than sorry.It's also very good that you are taking precautions at such an early stage.Just try and explain to your parents.Sit them down and talk to them.Tell them what you're feeling.Let me know what happens ok.
