It’s Only a Mole, Right?

May is Skin Cancer Awareness Month

Many women cherish a facial beauty mole. The American Academy of Dermatology recommends annual full-body exam­ina­tions for new moles or unexplained blemishes. A dermatologist or family member may examine you. With a mirror, you can also do it yourself. What types of moles (nevi) warrant further investigation by a medical dermatology professional?

Moles and skin cancer

Moles in themselves are not harmful. Most are congenital. Acquired moles (or common moles) can appear on your skin after you’re born. New moles may appear during hormone level changes or pregnancy.

If moles grow, change color, or become irregular, they might be precancerous. Hence, new moles are something you should bring to the attention of your doctor and keep under observation. Measure the diameter and take pictures while logging changes over time.

Skin Cancer Stages

Five Roman numerals (0 through IV) divide melanoma is divided into stages. Up to four letters (A through D), indicate a higher risk within each stage. Progres­sion is slow and it appears innocuous at first. During stage 0 (in situ), a small spot within the epidermis that resembles a mole may be all you see. Within stage I (localized tumor), the tumor grows deeper through the epidermis. At stage II (localized tumor), the cancer breaches the dermis with a visible ulceration.

As is the case with all cancers, early evaluation has better outcomes. But many people either do not notice new moles or minimize the seriousness. During stage III (regional spread), the cancer infiltrates to the lymph nodes. In stage IV (metastasis), it spreads to other organs.

More than 60% of all stage IV melanoma patients will develop brain metastases at some point. People may think of skin cancer as a disease that causes a nasty scar. Without intervention, you can die of skin cancer.

  • Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin.
  • Different types of cancer start in the skin.
  • Skin color and sunlight exposure can increase the risk of basal cell carcinoma and squamous cell carcinoma of the skin.
  • Basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis often appear as a change in the skin.
  • Tests or procedures can examine the skin to diagnose basal cell carcinoma and squamous cell carcinoma.

More. Beneath The Surface

Since skin cancer begins on the surface, it should be easier to detect and treat than visceral cancers. Often people conceal skin cancers with makeup, scarves, or clothing, as they do with minor skin eruptions. They bring it to the attention of physicians when it is deep and malignant.

Skin Cancer Stages

If you have access to tele­medicine or a medical email portal, upload good-quality digital photos for evalua­tion. Depending on the stage, you may receive a referral to either a dermatology or oncology professional.
