Re: Covered in suspicious moles?
If it's any consolation to you, melanoma is a particular aggressive and fairly quick growing cancer. So, if the mole you are speaking of were cancerous has been there for 5 years and hasn't changed, chances are it probably isn't cancerous. However, having it checked out is a very good idea. Barring that, keeping an eye on it yourself would be a given.
I'm so sorry to hear that the idea of getting to a dermatologist is cost prohibitive. That seems all to familiar for so many people. Perhaps once you are on your own, your financial situation might change?
As far as mole mapping, this isn't always something dermatologists will do for every patient. Mole mapping - at least clinically - can be very expensive and is usually done when there is a need. i.e. a person has already has an instance of melanoma. However, this doesn't mean you can't do an amatuer mole mapping. You will need to have a friend or family member help you, but it might be beneficial in the long run. All you will need is a digital camera with a good resolution, a steady hand, and objects to assist with determining size. Take the largest moles, or those that are most concerning to you, and make certain you have the best light possible. Try to get the best measurement - either will millimeters or small objects, such as paper clips or coins - and set them near the mole. Take as close a picture as possible, in as clear a focus as possible. Save these pictures, with the date taken. This would be a "baseline." Make certain you clearly identify where the moles are located on your body. You can leave it as a baseline, or take more pictures a year later, 5 years, 10 years, whatever. Or, if you think something has changed. Make certain, when re-taking the pictures, you use the exact same measuring device to get as accurate a measurment as possible.
Depending on how many moles you are concerned about, this can take quite a bit of time. However, it can give you some peace of mind, and, in the case a mole should change, you can actually show a doctor in what way a mole might have change and over what period of time.
