Research is still being conducted as to what causes moles. There is still a lot of debate concerning the genetic link between family members and this condition and just how strong that link is. It has been noted, however, that the link does indeed exist but there are still a range of unanswered questions when it comes to this topic.
As far back as one hundred years ago, doctors have been documenting their thoughts on the link between genetics and moles. A few began to document cases where both a parent and child suffered from the same sickness and they thought this might be related to the fact that both of them had moles. In this day and age we might be able to guess at Melanoma being the illness and with our advances in the medical field we can also tell that this might have been linked to the moles on their bodies.
Usually when a mother or father has a certain kind of skin that easily develops moles, some or all of their children will have the same problem. This might be linked to the type of skin they have.
Over time this link has become difficult to deny and the case has been strengthened by the fact that scientists are now aware of what is called an Atypical Mole Syndrome which is passed on from family member to family member. This syndrome is basically a genetic predisposition to developing atypical moles on the body. Moles that develop normally may present themselves as typical moles and they usually are not a problem but this is not always the case. If the moles begin to change shape or color they might begin to form into atypical ones which need to be closely monitored
A higher risk of developing Melanoma, which is a form of cancer, is also passed down from family members and this develops in or around the mole itself. This is why such caution needs to be taken when a mole appears to be unusual as it may be a sign of this illness. If family members can be made aware that they are at risk they might be persuaded to take extra precautions such as protecting themselves from the sun or checking their bodies for any changes that may have occurred in or around their moles.
If your family has very fair skin then the chances of you having the same complexion is fairly good. Usually, family members tend to share traits such as this and this includes other features such as fair hair and light eyes. Moles tend to develop more prominently in people with fair skin, especially if they spend a lot of time in the sun.
This link may be more difficult to pinpoint as it is not directly related to the development of the moles itself, it is merely linked to the type of skin that might be more predisposed to moles. This type of skin needs extra protection from the sun but if the necessary precautions are taken then the moles might not present as often as they would usually do.
