Moles and Skin Cancer

Moles and Skin Cancer

There are several types of skin cancer that involve the growth of new moles or changes in moles, so moles and skin cancer are actually linked together. Skin cancer is one of the most common of all forms of cancers that humans can develop, and more than a million people are diagnosed with certain types of skin cancers every year. What cancer involves is a transformation by normal cells where they multiply and grow beyond their normal controls, forming a mass known as a tumor which is most commonly known as a lesion when it relates to skin cancer tumors.

The relationship between moles and skin cancer most commonly exists in bodies that have malignant melanoma, which is an extremely invasive and aggressive form of cancer. Malignant tumors are tumors that invade and encroach upon neighboring tissues as they grow uncontrollably throughout the body. The process that cancer takes when invading the body is known as metastasis. Benign cancers do not metastasize, but malignant cancers tend to grow uncontrollably, slowly taking over the entire body to cause long term harm.

Malignant melanoma is an extremely aggressive form of cancer that spreads from one part of the body to another. If not treated early and aggressively, cancers like this can be extremely fatal. Some cancers start as precancerous lesions, while others form in new moles or already existing moles in the body. These are most commonly changes in the skin that do not begin as cancer, but rather become cancer over time. For example, nevus is a word for mole, and dysplastic nevi are moles that are abnormal. These abnormal moles can develop into melanoma over time if not treated early.

Moles or nevi are simply growths that exist on the skin, and they are actually rather common. Very few moles actually ever develop into cancer, but that does not mean that they will be normal moles forever. The average person has between ten and forty moles all over their body, and while some moles are flat, others are raised. Some moles may begin flat but may become raised over time. Moles that are round or oval and smooth, but that eventually change in color, shape, size or orientation should be checked out. While many moles are completely benign in nature, moles and skin cancer are still related and it is important to monitor the moles on your body to make sure that none of them are changing over time.

Dysplastic nevi, which are moles that are abnormal in nature, are not naturally cancerous by any means. However, there is still an ever present chance that these abnormal moles can turn into cancer in time. People who have dysplastic nevi often have a large number of them, and people who have many of these abnormal moles are more likely to develop melanomas. Melanomas can be developed in already existing moles, or in an area of normal skin that will develop into an abnormal mole. For this reason, it is important to understand the correlation between moles and skin cancer, because if you have a lot of moles, especially dysplastic nevi, there is a chance that skin cancer will eventually develop.
