What Percentage Of Moles Are Usually Cancerous
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Changing mole: It can be hard to tell sometimes but for the lay person, any mole that is changing color, character, bleeds, gets darker, gets irregular or has symptoms, should be examined by a physician knowlegeable about such lesions. A dermatologist is a specialist in this area. If you are even in doubt, get it checked out. Google warning signs of skin cancers. ...Read more
Remember your abcd's when thinking of melanoma. Look for moles with
boarders that are irregular
color differences within the same mole
diameter greater than 6mm
also any new mole or old that starts to itch, bleed or ulcerate should be of concern. Another rule is the ugly duckling rule. Which refers to a mole that looks distantly different from the others on your body. ...Read more
Depends on the mole: While moles are generally benign, or non-cancerous, there are some that can contain cancer. One class of mole, called congenital giant nevus, is very large and dark and can become a melanoma. Typical moles are very unlikely to be cancerous, but any concerning lesion should be evaluated by a physician. ...Read more
Are all moles that change cancerous? I've always had a lot of moles and I'm almost 35... some have changed. None are painful.
I have 4 moles with 2 or 3 shades of brown are they more likely to be atypical moles because there are 4 rather than cancerous?
It depends on size: Moles which are >4-5 mm in size (bigger than pencil eraser) are often considered abnormal or Atypical. If there is mixture of colors instead of one uniform color, then the moles become suspect for Melanoma. You should show these to your doctor who may consider doing a biopsy if there is suspicion of melanoma. The main warning sign of melanoma to watch for is a changing mole (in color or size) ...Read more
Cancer: It needs to be biopsied or completely removed by a physician. It then needs to be checked under the microscope by a pathologist to determine the type of cancer and how deep it invades the skin and underlying tissues. Some skin cancers, especially melanoma, have the ability to spread to distant parts of the body. You need more information from the doctors involved with this case. ...Read more

Spreads: The rule for all tumors is that if you leave them alone they will grow on you. Melanoma or a malignant mole can rapidly spread to lymph nodes and then disseminate to every known organ in the body. It can produce satellites adjacent to the primary, ulcerate and bleed. In rare instances spontaneous regression is seen probably because of shedding of tumor protein into the skin inducing immunity. ...Read more
Biopsy: Most doctors can tell a non-cancerous mole from one that might be cancerous. You could look up pictures on the web if you don't want to see your doctor. But if you are really worried show him/her next chance you get. Moles which are rough, increasing in size, or bleed or have areas of different color are suspicious. Smooth round flat stable ones are not very suspicious. ...Read more

It can be either: A changing mole raises suspicion that it could be melanoma, yet not all moles which are removed under such a suspicion turn out to be melanoma. The typical yield of melanoma in such biopsies is 1 in 5 turns out to be melanoma. So if a mole grows, you should show it to your doctor or seek opinion from a dermatologist. They may chose to biopsy it there and then or observe closely for some more time. ...Read more

If it was a cancer, it may reappear in the same spot or in th nearby areas like skin or lymph nodes draining the skin of this area.
Good luc. ...Read more
