Should I Be Worried About a New Mole?
Moles may seem like nothing more than an annoying blemish. However, they should receive particular attention due to their ability to become cancerous. Fortunately, knowing the signs to watch for can ensure early detection and a better prognosis.
Dr. Trevan Fischer, a certified complex general surgical oncologist, treats a variety of skin and other types of cancers using the most up-to-date innovative techniques at his private practice in Santa Monica, California.
In addition, he stays abreast of the latest discoveries and care recommendations as a clinical trial researcher at the Saint John's Cancer Institute.
Moles
Moles are created from clusters of pigment-forming cells and typically appear as small, dark brown spots. Most occur during early childhood and through the teen years, with adults often ending up with anywhere from 10 to 40.
Typically, moles last about 50 years and can change over time, including becoming lighter in color, raised, and having hairs develop on them.
Most are harmless. However, if a new mole develops or an existing mole changes, it is important to get it checked out.
Melanoma
Melanoma accounts for only about 1% of all skin cancers. However, it causes the most skin cancer-related deaths due to its aggressive nature. It can grow quickly and invade any organ. The good news is that melanoma has a cure rate of 99% when caught in the early stages.
Signs to watch out for
Red flags to watch for include new moles and changes to existing moles.
New moles
Though less common, a new mole can develop in adulthood. Causes could include exposure to ultraviolet radiation from the sun or tanning beds, fair skin, genetics, and having a weakened immune system. The mole could be benign or cancerous.
Changes to moles
Changes to existing moles can also signal a problem. The memory device "ABCDE" can help remind people what to look out for.
- A is for asymmetry. This is when one half of the mole is different from the other.
- B stands for border. If the edges are not smooth, it could indicate a problem.
- C equals color. A mole with uneven or different colors, such as black, brown, gray, red, or white, should be examined.
- D is for diameter. If the mole is larger than about 6 millimeters or the size of a pencil eraser, get it checked out.
- E means evolving. New or changing moles could signal an issue.
Catching skin cancer, and especially melanoma, early can allow for less invasive treatment and a better prognosis.
If you have noticed a new mole or seen changes in an existing one, Dr. Fischer can diagnose and, if necessary, treat it. Click to book an appointment or call the office today at 310-807-2688.
